Biggest issue I have had with the hollow 6-panel (cardboard) doors is humidity.

LOL  so we move  to places that are more affordable you think anyone want to live in Texas with that heat and humidity after living in San Deigo heck no but they go there because 350 to 500k buys you a super duper home.. and over a million basically a mansion.However those who own 750k homes that rent them for 3k that's not the best use of those assets either right ?

Justifying it with never having to worry about any future issues the smaller unit not being able to keep up with Virginia heat and humidity & the lesser R value of a mobile home vs. a traditional home.

The weather is gorgeous Oct to May... the July/Aug/Sept is a HOT and more recently HUMID **** show, but most people stay in doors.

It was always damp and humid, and even though the house was over 100 years old, I didn't think the constant dampness was good for the timbers of the house.It was an interesting property, the owner had moved there when she was 12 with her parents and was still living there under a life estate and was 98 years old when we bought the place. 

I say that because added humidity without proper venting can cause mold.High electric bill wouldn’t be my concern, but overloading circuits would be. 

Verify concrete dryness in accordance with ASTM F 1869 “Standard Test Method for Measuring Moisture Vapor Emission Rate of Concrete Subfloor Using Anhydrous Calcium Chloride” (moisture vapor transmission should not exceed three pounds per 1,000 square feet in a 24 hour period), F 2170 “Standard Test Method for Determining Relative Humidity in Concrete using in situ Probes” (relative humidity should not exceed 80%), or D 4263 “Standard Test Method for Indicating Moisture in Concrete by the Plastic Sheet Method” (no moisture present).

I suppose ocean is more expensive + high humidity.

The leak worsened, and in combination with the heat and humidity, the mold literally overtook his entire apartment unit.

In Indy we have tornados, freezing weather, high humidity, and flood zones that may cause challenges if you don't understand them from the onset.
