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. 

Section 8 folks have negative stereotypes but nobody is trashing a nice place with a nice landlord to risk potentially losing their voucher and having to deal with a Slum Lord.

That's where the housing authority directs Section 8 voucher holders to look.

Being the nice guy I am, I moved her and her daughter into a vacant unit I had while I had her unit repaired.The inspector for the agency she dealt with gave us until the end of the month to repair the unit and get it reinspected, then turned around and offered the tenant a new voucher for a new apartment across town and refused to sign off on my place, thus causing the tenant to break the lease.

big problem with section 8 here is that you really don't know exactly what their voucher is until you get your HAP contract back.

(I have no experience renting to section 8)...so my question is, if i have already stated a rental amount, can i change it when i decide to rent to someone with a section 8 voucher?
