The “air noise” like talking and TV is bearable but the “impact noise” from the floor above seems quite loud.

@Kenny D.We own multiple 3-family properties in the northeast and have changed boilers and hot air furnaces many of times (just did one last week).

No central air?

I’m an active duty military officer (Air Force) currently based in Washington State.

Formulate a plan --> rentals, Air BnB, flips, etc. 

Brand new open air malls still have a chance for great success.

the 8k I would assume is late fees etc, try cash for keys, he give cash(check) day tenant out, if eviction process could delay sale and lower sales price, I would not buy owner occupant with tenant in, or eviction pending,public record, would sell as if foreclosure, and if wants to rent out would make property have bad record, you dont care if they rent new or move in with family but must be out with walk thru, move in next day, yes self for couple days on air mattress, change locks, he can say has been rerented, do landlords truely do their own taxes or use online sites or have good accountants for write offs and costs?

The upstairs would be more of a loft style, with kitchenette connected to a good sized bed/living space by open air space with bath. 

The toilets, ovens, fridges, water heaters, faucets, and air conditioners that I've used to fix up my houses are all made in factories in the U.S.A. by workers that often are renters. 

You can then grab the over the air HDTV signals and there is no cost for local channels.I tried the HDTV antenna at our Idaho house, but we are a long way from any antennas on the lake.
