The most commonly listed minimum is 5.5sqft.6 - Heating and Cooling element.

The only real offer I got through FF was for $1700 a month, and I'd rather leave it empty than take that and pay for the heating bills and the extra wear and tear of long term renters.

Newer appliances, free nice laundry, 2nd floor, yard space, storage, clean bathroom, included heat, installed window A/C.Appraisal suggested the unit was worth 2,300 a month, which I felt was a bit high, so I listed it for $2,150 with no move in fee and a 2k deposit.

Prior to losing the home in foreclosure the previous owner had retaliated against the lender by cutting out most of the exposed electrical wiring and removing the heat and air units from the property. 

In the summer while the other half of the country is dealing with sweltering heat, i'm still hanging at the beach.

Air conditioned air leaking to crawlspace making crawlspace heat or cold depending on season causing more power bill to tenants.

Does it have material defects such as a roof, foundation, heating system issue etc?

And now pipes froze cause no heat, and now it's $14k more to fix pipes, I gotta walk away" and "seller" says "like hell you will, you destroyed my property, you messed up my credit, now I'm getting foreclosure warnings from bank, YOU CHEATED ME". 

None of the leases matched, the properties look like hey never got repaired , no heat , pipes frozen , 2,5ft sewer in the basement. 1/2 in gap between front door and door jam.

I actually had to make calls to fix the heat and broken doors and connected with the tenants 1 on 1.
