So that in mind, the "secret sauce" on how to get discounting from builders is doing it in a Win-Win manner. 

You may pay a bit more and make a little less, but playing the long term game is key in real estate.The types of structures could be lump sum (one price) or cost plus (meaning you pay the cost of material and labor plus a flat fee—more of an open-book model).I see some investors who want to pay for ALL the materials, which is excellent for the investor (more control of finishes & cost) and general contractor (if they are getting paid well).  

You raise a good question, and probably an excellent one for a CPA.  

Even if you go to small claims court and win, sadly you are unlikely to see any of the money.

Read the lease , if thats what it says and you and your daughter signed it , then they can take you to court and will probably win 

There're many excellent tax accountants (aka tax advisors, tax strategists, tax specialists and so on) who do not have a CPA license.

Seems like a win/win/win.

Thank you for helping to foster an excellent investing forum environment!

You MIGHT have a chance of winning in court.
