# Real estate and Org table formulas

This will be a 20 minute presentation on how I use org mode tables (specifically formulas) on how I can quickly see if a deal is feasible or not.
Topics will include:
- Creating Table Formulas
- Special Buffer Editing Formulas
- Formatting output
- Special Debugging just for formulas
- Creating Custom Formulas
- Automatically re-calculating rows/table
- Finally Putting it all together to tell at a glance if a property is ideal or not
Essentially bits and pieces from this section of the manual:

## Questions and answers
- Q: Pretty neat\-- Can you say how this is better than maintaining a
gui spreadsheet?
- A: As all things in life, this is preference. org tables are
text only and for me this is easier than learning yet another
tool (google spreadsheets/MS excel/etc) but totally up to you
:) Also, you can write your formulas in Elisp instead of
whatever crippled language you have to use in other
spreadsheets.+2 (move the logic to lisp to other package and
decouple/reuse it other documents, test it, etc.); Moving around
cols + rows - is also way faster than what one can do in GUI
spreadsheet apps
- Q: Is there a way to share the constants between the tables?
- A: You can create a constants for the entire buffer, or save
them as variables :)
- Q: Can you please provide the link to the org file?
- A: Currently the file is not hosted anywhere. I can put it in a
github repo in a bit :)
- Q:Is there a way to link to a cell in another row in the same table?
or other tables?
- A:I think i remember reading that it is possible to do the first
part of your question. I don\'t think you can do the 2nd part
about linking cells from other tables. I\'d recommend double
checking w/ the org docs since I can be misremembering things :)
- Update: Looks like it is possible -\>
