Many banks will also allow you to sell to a third party and waive the prepayment penalty.

Because proceedings become unmasked at the 60-day mark, parties are encouraged to settle or complete trial within that period.

If you are hiring a 3rd party management company to run it (which i recommend in case you want this to become your business - so you can scale) then work with them to create the pro-forma.  

Is there a resident portal or third party site for online payments or maintenance requests?

If so, how do you make it beneficial for both parties?

A JV is basically a partnership and no securities license is needed if only between 2 parties.

The financing agreement is a contract with a third party.

I could definitely see how it could be a tight rope to walk though, especially if either party (seller/buyer) has conducted multiple transactions with the agency before.

I know the construction side in and out, but the raising money part I am at infancy stage.  

All money should go through escrow - even deposits if they are not being held by a licensed broker that represents one of the parties to the transaction.
