A debt service loan is popular for that step.

The ways around that are to build a business around supporting their voucher and inspection program and spending no small amount of effort ensuring they are smoothly servicing your rentals. 

In a situation where you were doing an arbitrage (renting it from the owner, then yourself re-renting it to someone else) your costs to renovate/fix it up while you're using it would be able to be capitalized and depreciated by you once your rental was in service (available for rent to others). 

Yes, my banks require a 1.2 DSCR debt service coverage ratio, meaning they want to see rent 20% higher than the mortgage payment.

Amazing that this is the only business in America where you are providing a service for free at the moment.

There may be requirements to cover the trash service depending on the town.My first commercial loan was 30% down, 20 year term (adjusting after the first 5 years). 

I suspect they add this service to the tax bill but not positive on that. 

But around here some of the screening services that claim to do background checks do a lousy job of it.

It turned out that Lee Arnold is an ordained minister, so on Sunday morning of the 3-day seminar in Austin, he held a church service and preached a very convincing sermon.

All your properties may be perfect but if you are transparent about why something is not in service, it makes sense, and they agree it works just fine for long-term rentals.
