I know this is old, but weren't you still getting the guaranteed rent from the Sec 8 voucher.

Another niche that flies under the radar is housing voucher (formerly section 8) There is a negative stigma attached to it, but the returns can be pretty good as well.

What I did was confirmed that the tenant had a current voucher (without a current voucher, forget about going any further in my opinion).  

One side benefit is come tax time the title company dispersing the construction funds via a voucher system sends out 1099s to all the contractors for me.

Was the rents below market for the voucher??

Eventually, it all works out because his wife decides not to press charges and they go to marriage counseling and they are doing much better now.Several months have passed now and his voucher request for a 2 bedroom has just been approved and so he gives notice to me and his final day was yesterday.

Section 8 (housing choice voucher) is merely a voucher from a local housing authority that helps fill the gap for a low income tenant to be able to afford market rates.

If you have tenants that have 100% vouchers, it is likely that this pandemic had had no effect on your cash flow as this money comes direct from the government.However, I can attest that the communication difficulties that you are having with HACC are not uncommon right now.

One of the units is a Section 8 voucher apartment, but the rent is $675 vs the FMR rate for the area of over $1k.Are there any reasons that I wouldn't be able to raise the rent to at least near the FMR rate next time the lease renews?

So there are plenty of tenants with vouchers ready to rent, but just need a property that is approved for the section 8 housing program.
