After all this is the age of the unverified info share. 

We have a potential tenant (mother and middle school aged son) who has submitted an application, their finances check out and are willing to pay full price for rent.

I have spoken to an insurance agent in the area who stated the biggest factor is the age of the property, which in my case, is pretty old.I appreciate the input from everyone! 

I think I read The Richest Man in Babylon at that age.

I purchased a house with 8 acres attached about a year and a half ago at the age of 23.

The line of credit shows up on your credit score resulting in a lower credit utilization rate and increasing the average age of accounts, which are contributors to the FICO score.

A worry going forward is that as the house ages, repair costs will go up, and it does not cash flow nearly well enough to outsource all repairs from out of state.

Condition and age of property--Don't want a high maintenance property with a bunch of CapEx around the corner.Marketability--Will it be a desirable rental for quality tenants?

Sounds like you are living in a condo that is really old in age or was poorly and incorrectly renovated.It's common in older buildings to have thin sheet rock and also the insulation used in the walls had a lower value back then.Over time the insulation breaks down.If you can hear each other between the walls it is definitely not a person issue it is a building issue.Good luck on getting them to redo the walls and insulate to fix the problem.Your best bet is to move to a newer facility with proper sound deadening.If you moved to a town house on the end unit then you would only share one common wall.In an apartment you can have people below you,above you,beside you, and with poor sound control can be a nightmare for a tenant.No legal advice.
