That's a huge bonus right there. 

Mold is an added bonus for not having ventilation.And, an attic fan won't be enough...you'll need vents to allow the hot air to vacate. 

I'm hoping to receive a bonus for work within the next year and that will pay off whatever bad debt I have remaining.

Sure, these laws aren't perfect, but if you have reasonable rental criteria and screen properly, those laws will protect YOU as the landlord, and as a bonus, they make the screening process so much simpler.

Bonus if I can combine it with one of the grant programs provided by Baltimore City.

Any rental that is rented will be a bonus. 

Should I not need it all of it for taxes due to writing off expenses, then I consider what is left to be a bonus after filing taxes.

We never hired a management company, as it was not cost effective with rent we have been charging and it is only one house.Another question: If I do wait til Fall 2019 to sell, should I rip the carpet (up the stairs, living room hallways, bonus and bedrooms—2600sf house) and leave floors bare, (it’s light colored, horrible carpet) to allow buyers to add their own?

If not I really love the idea of creating huge wealth by transforming a whole area.

They're offering huge mileage bonuses.
