I'm not an attorney but, my suggestion is to have both parties write out what their roles, responsibilities & expectations.

I'm late to the party but just curious if you guys have overcome this.

Since you appear to live in Brooklyn I assume you will rely on a 3rd party property manager.

I do hope a MTR 3rd party data company comes along.

Best part is, my money continues to grow even while I have a loan out due to something called a non-direct recognition loan.

Please don't make this about party politics because then nothing will get done. 

I just sold a spec, I built a house for my self last year and finished a spec this year, I bough the lots at tax sale, and I was the GC, HVAC, Tile, Flooring, Cabinet, Painter, and Misc. guy, made a nice profit, but the crappy part is taxes, its like a flip, short term gains. good luck!

Everything needs to be reasonable and payment/cost needs to be similar to what you would see in an arms-length transaction with an unrelated party. 

Basically, like a 3rd party to hold the funds. ( You can not mix your personal funds with your retirement funds.) 

If they want to put limits on future contacts that is different than passing a law that changes a contract between 2 consenting, competent parties that was legal when entered into.When rent control is first passed and applied to existing leases, the government is changing the contract.
