So yes, agents buy leads from all over the place, but I am guessing you might be hard pressed to find an agent willing to pay large fees per lead as it could have permanent negative repercussions on their license.

I'm also considering making one of the units my permanent residence, which would lower the interest rate by default.

I would recommend to pursue eviction as it will go tenants permanent record, so in most cases they leave as soon as they get served by the sheriff because they realize that the landlord is not playing around.

Otherwise, it will be a continual thorn in the side every year, and it has the potential to damage landlord credibility.In your conversation with the landlord, emphasize that it is in both parties' best interest to diagnose and permanently fix this situation.

or is this a property that can be permanently split and rented out as a true duplex? 

The monthly rent on that house is only a few hundred bucks more than the mortgage payment (as you would expect with a no money down loan), but I try to take a longer more permanent view of my investments.

My advice is this...never let a temporary change a permanent. 

For other types of foreclosure prevention alternatives, a lender must record a rescission of a notice of default or cancel a pending trustee's sale if a borrower executes a permanent foreclosure prevention alternative.

That means they have permanent foundations according to FHA.

I recently spoke to my lender about permanent financing on a 440 SF home.
