[[!template text="Not very creative, but it is what it is." start="00:00:07.640" video="mainVideo-realestate" id="subtitle"]]
[[!template text="Now I just want to say that everything I talk about here" start="00:00:09.880" video="mainVideo-realestate" id="subtitle"]]
[[!template text="is in the Org Mode in the Emacs manual." start="00:00:13.052" video="mainVideo-realestate" id="subtitle"]]
[[!template text="I posted a link to the web version," start="00:00:15.903" video="mainVideo-realestate" id="subtitle"]]
[[!template text="but it should be inside of Emacs as well." start="00:00:17.910" video="mainVideo-realestate" id="subtitle"]]
[[!template new="1" text="Now before I start, I want to showcase the end goal." start="00:00:20.480" video="mainVideo-realestate" id="subtitle"]]
[[!template text="That way you know if you guys want to" start="00:00:25.097" video="mainVideo-realestate" id="subtitle"]]
[[!template text="actually see the talk or not." start="00:00:26.807" video="mainVideo-realestate" id="subtitle"]]
[[!template text="So I always think that's pretty cool to see" start="00:00:28.740" video="mainVideo-realestate" id="subtitle"]]
[[!template text="what you're actually going to build" start="00:00:30.492" video="mainVideo-realestate" id="subtitle"]]
[[!template text="before you start building it." start="00:00:31.518" video="mainVideo-realestate" id="subtitle"]]
[[!template text="Alright. So let me start off with the goal," start="00:00:32.680" video="mainVideo-realestate" id="subtitle"]]
[[!template text="the end goal. Here we have a simple table formula" start="00:00:34.286" video="mainVideo-realestate" id="subtitle"]]
[[!template text="and we have some constants, some values inside the list--" start="00:00:38.763" video="mainVideo-realestate" id="subtitle"]]
[[!template text="inside the table, I'm sorry," start="00:00:42.614" video="mainVideo-realestate" id="subtitle"]]
[[!template text="and some other stuff that we will get to," start="00:00:44.640" video="mainVideo-realestate" id="subtitle"]]
[[!template text="but for now... I don't want to spoil too much." start="00:00:47.673" video="mainVideo-realestate" id="subtitle"]]
[[!template text="I just want to give you a demo" start="00:00:49.280" video="mainVideo-realestate" id="subtitle"]]
[[!template text="of how it actually works." start="00:00:50.328" video="mainVideo-realestate" id="subtitle"]]
[[!template new="1" text="We have a few values. Let me first go over the constants." start="00:00:51.800" video="mainVideo-realestate" id="subtitle"]]
[[!template text="We have PMI, which stands for" start="00:00:56.095" video="mainVideo-realestate" id="subtitle"]]
[[!template text="private mortgage insurance," start="00:00:57.582" video="mainVideo-realestate" id="subtitle"]]
[[!template text="so it's insurance that you'll have to pay" start="00:00:57.591" video="mainVideo-realestate" id="subtitle"]]
[[!template text="depending on how much money you put into the deal." start="00:01:00.537" video="mainVideo-realestate" id="subtitle"]]
[[!template text="The property tax, which is self-explanatory," start="00:01:03.640" video="mainVideo-realestate" id="subtitle"]]
[[!template text="the tax that you owe for owning the property," start="00:01:06.068" video="mainVideo-realestate" id="subtitle"]]
[[!template text="and then home insurance," start="00:01:09.317" video="mainVideo-realestate" id="subtitle"]]
[[!template text="and the interest rate at the loan that you get." start="00:01:11.107" video="mainVideo-realestate" id="subtitle"]]
[[!template text="So, here we have a few columns." start="00:01:13.440" video="mainVideo-realestate" id="subtitle"]]
[[!template text="The first one is called House," start="00:01:15.667" video="mainVideo-realestate" id="subtitle"]]
[[!template text="which I usually just put a description of the house" start="00:01:17.412" video="mainVideo-realestate" id="subtitle"]]
[[!template text="with the link of the posting," start="00:01:20.624" video="mainVideo-realestate" id="subtitle"]]
[[!template text="the price of the house," start="00:01:21.127" video="mainVideo-realestate" id="subtitle"]]
[[!template text="the percentage down payment (this I play around with" start="00:01:22.494" video="mainVideo-realestate" id="subtitle"]]
[[!template text="to see how much the deal will be structured)," start="00:01:26.190" video="mainVideo-realestate" id="subtitle"]]
[[!template text="the down payment (which is calculated from" start="00:01:27.474" video="mainVideo-realestate" id="subtitle"]]
[[!template text="the previous two columns)," start="00:01:30.529" video="mainVideo-realestate" id="subtitle"]]
[[!template text="the monthly mortgage (which is calculated as well)," start="00:01:31.755" video="mainVideo-realestate" id="subtitle"]]
[[!template text="and then the tenant income (which is what I suppose" start="00:01:34.145" video="mainVideo-realestate" id="subtitle"]]
[[!template text="would be an example of the tenant income" start="00:01:37.996" video="mainVideo-realestate" id="subtitle"]]
[[!template text="that I can potentially make off the property," start="00:01:41.006" video="mainVideo-realestate" id="subtitle"]]
[[!template text="the 1% rule and the ROI." start="00:01:42.753" video="mainVideo-realestate" id="subtitle"]]
[[!template text="I'll quickly go over the last two columns." start="00:01:45.540" video="mainVideo-realestate" id="subtitle"]]
[[!template text="So first is the 1% rule." start="00:01:47.708" video="mainVideo-realestate" id="subtitle"]]
[[!template text="The 1% rule is essentially" start="00:01:49.300" video="mainVideo-realestate" id="subtitle"]]
[[!template text="a "rule," in quotes, that says that" start="00:01:50.880" video="mainVideo-realestate" id="subtitle"]]
[[!template text="if a property matches this specific formula," start="00:01:53.589" video="mainVideo-realestate" id="subtitle"]]
[[!template text="it is a good deal to look into." start="00:01:56.278" video="mainVideo-realestate" id="subtitle"]]
[[!template text="So for example, the first two pass," start="00:01:58.320" video="mainVideo-realestate" id="subtitle"]]
[[!template text="and the last one does not pass." start="00:02:00.890" video="mainVideo-realestate" id="subtitle"]]
[[!template text="The last one, at a quick glance," start="00:02:02.677" video="mainVideo-realestate" id="subtitle"]]
[[!template text="we can just ignore it and say," start="00:02:04.105" video="mainVideo-realestate" id="subtitle"]]
[[!template text=""hey, that's not going to fly,"" start="00:02:05.472" video="mainVideo-realestate" id="subtitle"]]
[[!template text="we'll just ignore it." start="00:02:06.477" video="mainVideo-realestate" id="subtitle"]]
[[!template text="I won't go too much into details." start="00:02:08.000" video="mainVideo-realestate" id="subtitle"]]
[[!template text="That's just a brief summary." start="00:02:09.891" video="mainVideo-realestate" id="subtitle"]]
[[!template new="1" text="So now the ROI is the return on investment." start="00:02:11.520" video="mainVideo-realestate" id="subtitle"]]
[[!template text="So it says "how much of a return am I getting" start="00:02:14.149" video="mainVideo-realestate" id="subtitle"]]
[[!template text="on the amount that I invested?"" start="00:02:17.600" video="mainVideo-realestate" id="subtitle"]]
[[!template text="So let's say you put in $12,000," start="00:02:18.960" video="mainVideo-realestate" id="subtitle"]]
[[!template text="and at the end of the year, you cashflow $6,000." start="00:02:21.168" video="mainVideo-realestate" id="subtitle"]]
[[!template text="So if you calculate the ROI off of that," start="00:02:23.456" video="mainVideo-realestate" id="subtitle"]]
[[!template text="you get a 50% return on investment." start="00:02:26.127" video="mainVideo-realestate" id="subtitle"]]
[[!template text="In two years, you'll make your money back," start="00:02:28.477" video="mainVideo-realestate" id="subtitle"]]
[[!template text="which is pretty good." start="00:02:30.086" video="mainVideo-realestate" id="subtitle"]]
[[!template text="Then all the rest of the years," start="00:02:31.734" video="mainVideo-realestate" id="subtitle"]]
[[!template text="you'll just slowly be reaping in all that," start="00:02:32.719" video="mainVideo-realestate" id="subtitle"]]
[[!template text="all the excess cash flow." start="00:02:34.348" video="mainVideo-realestate" id="subtitle"]]
[[!template text="But yeah, that's it in a nutshell." start="00:02:36.640" video="mainVideo-realestate" id="subtitle"]]
[[!template new="1" text="So let me demo it real quick." start="00:02:40.040" video="mainVideo-realestate" id="subtitle"]]
[[!template text="So for example, I'm going to change the down payment," start="00:02:42.270" video="mainVideo-realestate" id="subtitle"]]
[[!template text="but I want you to pay attention" start="00:02:44.259" video="mainVideo-realestate" id="subtitle"]]
[[!template text="to this column [down payment]" start="00:02:45.745" video="mainVideo-realestate" id="subtitle"]]
[[!template text="and the monthly mortgage column." start="00:02:48.214" video="mainVideo-realestate" id="subtitle"]]
[[!template text="So right here [down payment] is $25,000," start="00:02:49.840" video="mainVideo-realestate" id="subtitle"]]
[[!template text="and here [monthly mortgage] is around $1,200," start="00:02:51.727" video="mainVideo-realestate" id="subtitle"]]
[[!template text="a little under $1,300." start="00:02:53.473" video="mainVideo-realestate" id="subtitle"]]
[[!template text="So what happens if I say, you know," start="00:02:55.180" video="mainVideo-realestate" id="subtitle"]]
[[!template text="what I'm going to change the down payment" start="00:02:57.350" video="mainVideo-realestate" id="subtitle"]]
[[!template text="to 5% instead, because I just" start="00:02:58.796" video="mainVideo-realestate" id="subtitle"]]
[[!template text="don't want to put 10." start="00:03:00.949" video="mainVideo-realestate" id="subtitle"]]
[[!template text="So let's just put say 5." start="00:03:02.560" video="mainVideo-realestate" id="subtitle"]]
[[!template text="Then I tab out of here, and voila -" start="00:03:04.126" video="mainVideo-realestate" id="subtitle"]]
[[!template text="you see it updated to half of $25,000." start="00:03:06.275" video="mainVideo-realestate" id="subtitle"]]
[[!template text="So now it's $12,000," start="00:03:08.523" video="mainVideo-realestate" id="subtitle"]]
[[!template text="and this [monthly mortgage] went up" start="00:03:09.947" video="mainVideo-realestate" id="subtitle"]]
[[!template text="over actually $1,300," start="00:03:10.690" video="mainVideo-realestate" id="subtitle"]]
[[!template text="and then this [1% rule] hasn't changed at all" start="00:03:12.234" video="mainVideo-realestate" id="subtitle"]]
[[!template text="and the ROI is there." start="00:03:14.784" video="mainVideo-realestate" id="subtitle"]]
[[!template text="So one thing that I should mention is" start="00:03:17.680" video="mainVideo-realestate" id="subtitle"]]
[[!template text="everything that I'm putting here" start="00:03:19.148" video="mainVideo-realestate" id="subtitle"]]
[[!template text="is just example numbers," start="00:03:20.194" video="mainVideo-realestate" id="subtitle"]]
[[!template text="should not be taken into literal real estate advice." start="00:03:21.280" video="mainVideo-realestate" id="subtitle"]]
[[!template text="I just want to put that out there." start="00:03:25.635" video="mainVideo-realestate" id="subtitle"]]
[[!template text="These are just examples to show you" start="00:03:26.860" video="mainVideo-realestate" id="subtitle"]]
[[!template text="how you can potentially make it on your own," start="00:03:28.368" video="mainVideo-realestate" id="subtitle"]]
[[!template text="do the formulas on your own." start="00:03:30.520" video="mainVideo-realestate" id="subtitle"]]
[[!template new="1" text="Alright, so another cool thing that I did was" start="00:03:32.240" video="mainVideo-realestate" id="subtitle"]]
[[!template text="if there is no tenant income and I tab," start="00:03:35.651" video="mainVideo-realestate" id="subtitle"]]
[[!template text="it says "Enter Tenant Income"." start="00:03:37.738" video="mainVideo-realestate" id="subtitle"]]
[[!template text="So if I don't put anything," start="00:03:40.049" video="mainVideo-realestate" id="subtitle"]]
[[!template text="it will automatically tell me, hey," start="00:03:41.033" video="mainVideo-realestate" id="subtitle"]]
[[!template text="I can't calculate without the tenant income." start="00:03:42.400" video="mainVideo-realestate" id="subtitle"]]
[[!template text="I can also do this right here [ROI field]," start="00:03:44.920" video="mainVideo-realestate" id="subtitle"]]
[[!template text="say the same thing, Enter Tenant Income," start="00:03:46.608" video="mainVideo-realestate" id="subtitle"]]
[[!template text="but I just didn't put it for whatever reason, but" start="00:03:48.476" video="mainVideo-realestate" id="subtitle"]]
[[!template text="after this video, you should be easily able to" start="00:03:50.564" video="mainVideo-realestate" id="subtitle"]]
[[!template text="put it without much struggle." start="00:03:53.813" video="mainVideo-realestate" id="subtitle"]]
[[!template text="Alright, so if that's something you're interested in," start="00:03:57.400" video="mainVideo-realestate" id="subtitle"]]
[[!template text="then keep watching." start="00:04:00.131" video="mainVideo-realestate" id="subtitle"]]
[[!template new="1" text="So let's go over the basics first." start="00:04:02.240" video="mainVideo-realestate" id="subtitle"]]
[[!template text="So, how do we create a table?" start="00:04:05.240" video="mainVideo-realestate" id="subtitle"]]
[[!template text="Well, we can do M-x org-table-create." start="00:04:07.400" video="mainVideo-realestate" id="subtitle"]]
[[!template text="If we run that it, will prompt us in a minibuffer." start="00:04:10.369" video="mainVideo-realestate" id="subtitle"]]
[[!template text="It says table size, columns times row." start="00:04:14.302" video="mainVideo-realestate" id="subtitle"]]
[[!template text="Usually it's rows times columns," start="00:04:16.893" video="mainVideo-realestate" id="subtitle"]]
[[!template text="but it is what it is." start="00:04:18.178" video="mainVideo-realestate" id="subtitle"]]
[[!template text="So let's just leave" start="00:04:19.602" video="mainVideo-realestate" id="subtitle"]]
[[!template text="the default of 5 times 2, and voila, we get this." start="00:04:20.466" video="mainVideo-realestate" id="subtitle"]]
[[!template text="Beautiful. Awesome." start="00:04:24.960" video="mainVideo-realestate" id="subtitle"]]
[[!template new="1" text="So the other way is using the magical C-c C-c" start="00:04:26.400" video="mainVideo-realestate" id="subtitle"]]
[[!template text="in Org Mode, which basically is context-aware" start="00:04:29.511" video="mainVideo-realestate" id="subtitle"]]
[[!template text="and does anything, does the right thing like," start="00:04:32.402" video="mainVideo-realestate" id="subtitle"]]
[[!template text="almost 100% of the time, which is pretty amazing." start="00:04:36.054" video="mainVideo-realestate" id="subtitle"]]
[[!template text="Alright, let's just say I write a pipe, some words," start="00:04:38.600" video="mainVideo-realestate" id="subtitle"]]
[[!template text="and then another pipe, Gopar, and then" start="00:04:42.432" video="mainVideo-realestate" id="subtitle"]]
[[!template text="another pipe. Let's just say we're trying to" start="00:04:44.680" video="mainVideo-realestate" id="subtitle"]]
[[!template text="write it out via text, because in Org mode" start="00:04:47.269" video="mainVideo-realestate" id="subtitle"]]
[[!template text="everything has text." start="00:04:50.600" video="mainVideo-realestate" id="subtitle"]]
[[!template text="There's nothing fancy about it." start="00:04:51.547" video="mainVideo-realestate" id="subtitle"]]
[[!template text="If I do C-c C-c, Org mode should automatically be" start="00:04:53.380" video="mainVideo-realestate" id="subtitle"]]
[[!template text="context-aware that this area is a table." start="00:04:57.673" video="mainVideo-realestate" id="subtitle"]]
[[!template text="So, C-c C-c, boom. So if I press enter, another column." start="00:04:59.840" video="mainVideo-realestate" id="subtitle"]]
[[!template text="If I press tab, it should automatically move me." start="00:05:04.295" video="mainVideo-realestate" id="subtitle"]]
[[!template text="So yeah, so that's pretty much it." start="00:05:06.964" video="mainVideo-realestate" id="subtitle"]]
[[!template text="That's how you get started into the column." start="00:05:09.392" video="mainVideo-realestate" id="subtitle"]]
[[!template text="So, I'm assuming most of the people here already know that." start="00:05:11.920" video="mainVideo-realestate" id="subtitle"]]
[[!template text="This is just the primary basic review." start="00:05:15.592" video="mainVideo-realestate" id="subtitle"]]
[[!template new="1" text="So, let's first go..." start="00:05:17.960" video="mainVideo-realestate" id="subtitle"]]
[[!template text="Let's go dive right into our first formula." start="00:05:19.808" video="mainVideo-realestate" id="subtitle"]]
[[!template text="So I copied some values over here," start="00:05:22.820" video="mainVideo-realestate" id="subtitle"]]
[[!template text="just to save time, and the columns." start="00:05:24.767" video="mainVideo-realestate" id="subtitle"]]
[[!template text="So, let's go ahead and say that" start="00:05:27.697" video="mainVideo-realestate" id="subtitle"]]
[[!template text="we have single family house," start="00:05:29.164" video="mainVideo-realestate" id="subtitle"]]
[[!template text="and the price is a hundred thousand." start="00:05:30.750" video="mainVideo-realestate" id="subtitle"]]
[[!template text="And, Let's say that I want the price," start="00:05:33.019" video="mainVideo-realestate" id="subtitle"]]
[[!template text="the down payment that I want to put is 10%." start="00:05:34.164" video="mainVideo-realestate" id="subtitle"]]
[[!template text="Right. Alright. 10%. Now if I tab" start="00:05:36.432" video="mainVideo-realestate" id="subtitle"]]
[[!template text="or go to the next column, nothing happens." start="00:05:40.528" video="mainVideo-realestate" id="subtitle"]]
[[!template text="Why is that? Well, it's because" start="00:05:42.394" video="mainVideo-realestate" id="subtitle"]]
[[!template text="(you probably guessed it)" start="00:05:43.880" video="mainVideo-realestate" id="subtitle"]]
[[!template text="we haven't written or tied any table formulas." start="00:05:44.985" video="mainVideo-realestate" id="subtitle"]]
[[!template text="So we're saying, alright, enough talk." start="00:05:47.756" video="mainVideo-realestate" id="subtitle"]]
[[!template text="How do we do that?" start="00:05:49.564" video="mainVideo-realestate" id="subtitle"]]
[[!template text="Well, the answer is very simple." start="00:05:50.540" video="mainVideo-realestate" id="subtitle"]]
[[!template text="We do a pound sign (#), if I can find it." start="00:05:52.094" video="mainVideo-realestate" id="subtitle"]]
[[!template text="#+ and then we do TBL for table" start="00:05:54.984" video="mainVideo-realestate" id="subtitle"]]
[[!template text="and then FM for formula." start="00:05:58.713" video="mainVideo-realestate" id="subtitle"]]
[[!template text="So, table formula, and the column." start="00:06:01.120" video="mainVideo-realestate" id="subtitle"]]
[[!template text="So this, you're already halfway" start="00:06:03.429" video="mainVideo-realestate" id="subtitle"]]
[[!template text="to writing your first table formula." start="00:06:04.935" video="mainVideo-realestate" id="subtitle"]]
[[!template text="So let's say we want to automatically," start="00:06:07.064" video="mainVideo-realestate" id="subtitle"]]
[[!template text="Let's just, for exercise," start="00:06:09.172" video="mainVideo-realestate" id="subtitle"]]
[[!template text="we want to put the down payment," start="00:06:10.979" video="mainVideo-realestate" id="subtitle"]]
[[!template text="just put some type of value in there," start="00:06:13.190" video="mainVideo-realestate" id="subtitle"]]
[[!template text="just to make sure that it's working." start="00:06:14.616" video="mainVideo-realestate" id="subtitle"]]
[[!template text="So the way Org Mode refers to columns is," start="00:06:16.383" video="mainVideo-realestate" id="subtitle"]]
[[!template text="we start with the dollar sign ($) and then" start="00:06:20.993" video="mainVideo-realestate" id="subtitle"]]
[[!template text="we put the number that the column is." start="00:06:24.141" video="mainVideo-realestate" id="subtitle"]]
[[!template text="Indexes start with one, not a zero." start="00:06:26.869" video="mainVideo-realestate" id="subtitle"]]
[[!template text="As most of us watching are programmers," start="00:06:29.114" video="mainVideo-realestate" id="subtitle"]]
[[!template text="we're probably used to starting with zero," start="00:06:31.624" video="mainVideo-realestate" id="subtitle"]]
[[!template text="but it starts with one." start="00:06:33.793" video="mainVideo-realestate" id="subtitle"]]
[[!template text="So one, two, three, four, five." start="00:06:34.960" video="mainVideo-realestate" id="subtitle"]]
[[!template text="So down payment is the fifth column," start="00:06:38.331" video="mainVideo-realestate" id="subtitle"]]
[[!template text="we say five, and then we say equal to," start="00:06:39.655" video="mainVideo-realestate" id="subtitle"]]
[[!template text="let's say Gopar." start="00:06:42.304" video="mainVideo-realestate" id="subtitle"]]
[[!template text="Then we do C-c C-c to evaluate it," start="00:06:44.289" video="mainVideo-realestate" id="subtitle"]]
[[!template text="and the table is automatically updated." start="00:06:47.938" video="mainVideo-realestate" id="subtitle"]]
[[!template text="Look at that." start="00:06:50.546" video="mainVideo-realestate" id="subtitle"]]
[[!template text="So when you do just this, dollar sign ($) 5," start="00:06:50.957" video="mainVideo-realestate" id="subtitle"]]
