But in the end well worth the challenges that you may face. I

I believe the biggest issue many landlords currently face is the over supply of new housing that was rushed to the market due to a number of factors including the changing  tax abatement legislation and favorable financing terms that were available when these properties were first purchased.

The problem most people face is they are not willing to sacrifice their privacy to get ahead quicker. 

Since you're tying yourself at the hip to this person, connecting face to face is a big help.

Preferably, a window envelope where enough of the envelope face is window allowing the EDDM indicia to be visible.- or -consult a local bulk-mailer and ask if they have a suggestion.

Every time I fall on my face I am 5’9†closer to my goal.

Also what unexpected issues did you face? I

Today our portfolio is more rentals than land contracts, but we still handle and sell on land contracts when the conditions are right for the seller.As someone who has serviced, managed, and owned homes on land contracts I can tell you the biggest risk you face is foreclosure and damage. 

@Scott AnthonyThe issue that you are going to face is that you are in a hot market and asking the seller to agree to jump through many hoops for you.

But looking the deal that seems to be slapping you in the face, I have to re-comment on what seems to be some blindness due to greed.
