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

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?

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

Pete Beach and Treasure Island heating up, it might be worth tapping into that dormant potential.

She will never be happy with the heat, she can barely afford the place, and she's regularly late with rent.

Stay away from electric heating - this is a tip for all investing to be honest. 6.

Given this is where my major operating expenses fell (beyond taxes and insurance), keeping this cost lower, by average, helps my cash flow.I invest in older neighborhoods, so the 2-4 unit properties, typically have single water meter, maybe single electric, and many have radiator heat with a single boiler.  

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.

Only tankless water heaters, extra insulation, heating/cooling, etc....
