The typical income from a free and clear rental would probably be $800-1500/month - and on a financed rental probably $300/month on a good day in today’s market.  

Keep an eye out for stuff like that.If none of that works, you’re probably in it for the long haul until they leave on their own.

Alternatively, I feel that a property manager could probably rent the property out and cash flow even after they take their cut, but I am worried about the screening process and potential tenants destroying my new home.

if it were me, I would probably take the drywall down from one side, make sure there is good insulation installed properly with no air gaps, install the quietcrete and see how it is. then if still bad, roll on some green glue and another thin sheet of drywall.

Heck, I was nervous on one of my most recent purchases because it was my biggest ever - and I've done over 100 transactions.Your current house is probable a Class A property - which is the easiest to manage. 

It probably will with good management in place.

I’m open to flipping, renting, or exploring other strategies.My mantra is to test new things “fast and cheap,” so I’ll probably begin investing locally in CT before considering otehr markets across the US. 

2: bigger picture, I could probably find 100 doors like this in this same market. 

They won't be able to fix that problem as there is probably a small leak in a pipe or a crack in the foundation or a bit of water coming in from somewhere or moisture building up in the home.I also agree with Nathan about taking the first contractor to small claims court.
