You sign an agreement with them (workout agreement, loan modification, forbearance agreement) that spells out the details.

@Mike Hartzog  if you contact Mike and go to his website I am sure he spells it out chapter and verse.also @Dave Van Horn  probably has this info written out as well. 

My keyword alerts include Capital Hill, Capitol Hill (Spell it both correctly and incorrectly), Silver Spring, Rockville, Arlington, Montgomery County, Prince George's County, PG County, Arlington, Alexandria, Trinidad, Dupont, Logan, Columbia Heights, Gaithersburg, Fairfax and so on and so on.

If not, there are probably other options spelled out in there.

I would also spell out the remaining lease term and that you expect the monthly lease payment of X dollars on the due date of every month.

Bill spelled it out pretty well, $2000 parking fines and the haters only need to get 3 complaints to stick in 2 years and you can never vacation rent that property again.

Make sure all of your supporting analysis on the cashflow of the properties is spelled out clearly for a lender. 

So it's just spelling out what the co-op commission is so we're all in the open and the seller understands that I am compensating the other agent fairly and not harming their chances at a solid offer by going cheap on the co-op fee. 

Awesome information, really appreciate you taking the time to spell this out for me!

if your a beginner highly unlikely your going to get Zero money down deals.. there will be some closing cost some cost involved.. you should work on some kish up front then go shopping.. nothing spells failure quicker than under funded.
