There is more housing programs than can count. 

You mentioned that you're not interested in grants or fundraising, I'm curious what type of operating budget and actual program you have in mind.

The property either has to go through the tax sale process, receivership, or some other program (donation, etc.) to have the liens abated. 

Santarelli,Does your company have any multi-family dwellings available for this program you offer, or is it all SFR?

I'm piloting a new construction program that's building a generational style home 6 bedroom 4 bathroom, 2500 sq ft house in a class B/C area.

They are MUCH more responsive and even managed to recuperate most of the owed rent via landlord/tenant assistance programs.

Before using such a program get your own estimates.   

These borrowers are typically out of the market for extended periods of time, have limited contacts in the debt world, lack understanding of how different loan programs work, and are susceptible to working with the one bank / credit union loan officer that they know through their family, friends, church group, college, etc.

And the best part is they help you through the entire process of learning how to run the program with many tips for hosting an STR.

I went to someone who was considered a reputable broker and he said he had a great new program.
