They could have issues with your property IE a tree root is making their sprinkler system leak etc.

This prevents sophisticated professional tenants from filing an appeal to buy another free month.

There are obvious signs of deterioration that are preventable.

I hope that you have changed the locks and secured your property to prevent anyone else with a key to return.

That WILL prevent you from refinancing unless that property is worth way more than you owe.

The roots are already lifting up the pavement and causing potential hazard, it is just a matter of time until it finds it way to the sewer line.

I am willing to pay the extra to have the pluming main line scoped looking for tree roots ect.  

A 2 fam with permit almost always have to be owner occupied which prevents you from buying it and renting both apartments. 

This will prevent this situation from happening 100% of the time.

Chris, Thank you for your quick response, I was looking to do a different strategy besides mass mailing, and I can see how preventing a foreclosure from happening, that would be a direct lender collaboration that I would have to work on indeed.
