I'm struggling a little bit on deciding the best agreement to make sure I can get some cash flow, payback the HELOC, and not drive the new mortgage up too much with the Refi out of the HELOC.

Review their management agreement.

Our loan minimum is $75,000 and we go up to $10 million.

On the initial agreement, it clearly stated that the buyer was going to be using financing and listed the terms of their financing

Very simple as Chris notes its just an up front agreement..

We need a buyer's representation agreement signed before we can show. 

We have a PMA, but it doesn't  seem to address these things in a way that is specific enough to where they're violating the agreement. 

Total rent s/b minimum $2,250 but with housing vouches, $2,550

Zoning Ordinance ExceptionsSome properties in the target zone don’t meet the minimum lot area or width size requirements under the zoning ordinance, yet houses exist on smaller-sized neighbor lots.How could these properties get approval for development?

This raises a question because we had a lease agreement on file showing a rental amount of $2,000 per month."
