Its our practice to provide an interested party with the financial information needed to analyze a property.  

I've also contacted investors in my area and offered them half of all my deals for 6 months if they can help walk me through the process of getting all the documentation in order and in a way that it protects all parties involved and no one seems to knows that. 

The actual video has all the stuff you said ( sqft, beds, bath etc.. ) and we send that as a follow up to the interested parties as well as posting it once it goes live on the MLS.

Maybe 7% with a 3 year balloon would work for all parties?

I use this method for most of my acquisitions.My own cash, line of credit, private party and temporary financing make the acquisition.  

Long leases are traps for both parties. 

Interested parties simply contacted our realtor (he had applications at the open house) with all of the required documentation (paystubs, application, application fee).

Independent third party assessment will be considered an important part of the enhanced prudential standards.

After that you can do seller financing, private party loans, portfolio loans, commercial financing.  

To you this could mean that while most areas have very low dollar margins leaving little room for a third party, in NYC margins are much higher in dollar terms so if you can find a way to work with someone they may have money to pay you out.
