While this isn't a help to you now, it may be to others reading, don't be a nice guy in the manner that you are/were a nice guy. 

I've noticed on two occassions when then downstairs tenant has an issue with me, there is dog feces waiting for me when I step out of my vehicle.I placed a letter on the door stating to pick up the dog shi* in a timely manner please.She places a letter on my door showing a 150$ bill for a snow plowing and said you are welcome to reimburse me or take this off my rent..I'm not sure the rules for Akron, OH but I read for Ohio that the tenant is responsible for snow plow. 

I have always made the needed repairs to my properties in a timely manner, and my tenants have always paid on time or have let me know if they were not able to pay and when they plan on paying rent. 

Look for mortgage rates to rise this year as the Federal Reserve has begun the process of normalizing their policies in response to sustained inflation reads - including withdrawing support for mortgage backed securities.

I just suspect that you were taken advantage of in this... the sellers/flippers were your agents also, and did not act in a fudiciary manner on your behalf. 

I'd like to use the basement as additional bedrooms and could still add the bathroom since there is existing plumbing already, but the expense of egress windows and getting someone to do it in a timely manner is damn near impossible.

I understand this question probably has a million different answers but trying to figure out if anyone has done this before in this manner and what would be fair or not fair.

I think it's creativity, innovation, sustainability

But is this something that I should have written out in a professional manner in order to present it.

However, there are markets whose demand is being driven up beyond sustainable levels.
