@Rhea Jackson  I currently live in Sumner county, which also has good schools, a hair below Williamson county in rankings.  

I actually rent some commercial space downtown Ashland, the hair salon next to Nicks Pizza.

You might have to find a small type catch all brokerage that dabbles in residential and small time commercial.These types of firms do residential and a few land sales and occasionally a small gas station or inherited type small building commercial.For the experts that only do one asset class the small deals like this do not make sense as they typically have a lot of (hair) on the deal meaning many issues to work through.

In addition to damage to floors, grass, woodwork and walls, we've learned that dog hair can cause problems for hvac units and bath tub drains.

You won't find a commercial lender at 85% with this hair on the deal. 

I was able to fill each space with photographers, hair salon, insurance agent, recording studio, background check company, cpa, medical massage and a 3000 sq ft floor to a non-profit dance studio.I often bring the group together for happy hours on my dime, networking meetings etc.  

For the tankless system that I would need (I want an outdoor unit in order to re-claim as much closet space as possible inside) I have received 4 bids ranging from just a hair over 2k all the way to 3.5k.  

If the breaker has been replaced and the area around the main panel doesn't reek of burning plastic (electrical components melting  smell about as distinctive as burning hair) there is no safety issue. 

The business is a hair salon it has three seats and one is for rent.

OK, if 240 is just a hair under market value, I'm confused as to how this is a great investment, unless you are expecting some crazy appreciation or can rent it out for some obscene number.
