If there are unpaid taxes, kindly push the taxing authorities to follow their tax sale guidelines so YOU can get it back on the tax rolls....and you want them to keep you informed of the progress.#5. 

I have a Chattanooga Housing Authority letter confirming the current rental rate as of Oct 2020.

(Cue the microphone drop sound)"Not necessarily, the housing authorities have a budget also and just not a limitless pot of money. 

The agent was your representative, you authorized the contractor, he gave you his opinion and you accepted it.

Most residents are on section 8.As a neighborhood landlord, I feel the neighborhood has formed an antagonism against me (mainly because landlords may be viewed as “authority” figures or gatekeepers, so to speak).

I am screening tenants and two previous landlords have asked that I send them a landlord authorization form or a rental reference authorization form.

Even in city of Boston there's Metro Housing, Boston Housing Authority, etc. 

If your parents or any other friends/family have great credit scores with long history ask if they can add you as an authorized user to their credit card(s) which will help give you a boost, but otherwise work on getting your own credit card and consistently using it in small amounts and immediately paying it off.Also work on saving as much money as possible so you have reserves and money towards a down payment as soon as you're ready to make a move.  

Some neighbor must have seen this spectacle every evening and contacted the authorities. 

Not sure what city you are in but just google Housing Authority and your city name to get to their website.
