But it's a 3/2 and I think I could rent it for $1000-1200, has a lot of NEW things already in it (AC/heating, kitchen cabinets, appliances, flooring) but bedrooms need to be finished remodeling. 

Summer months are always popular for both locals and again those from the south looking to escape the summer heat.  

As for heat loss along the way why does it matter?

Here is what we have found and I will probably catch some heat for some of the things I have to say, because it does not sound "investor-friendly".

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. 

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.

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

Also to reduce sun from heating buildings and for shade.  

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