Also, air conditioning removes moisture/humidity from the interior airspace, and nearly every home in the Carolinas runs AC during the warm months.Crawlspaces tend to be where the majority of problems occur.

I have a rental with ceiling fans in every room, I am afraid if they start making noise, or don't produce enough air for tenants liking I will get complaints and they will ask me to replace them. 

I then added central air.

Does this approach go by some sort of moniker or buzzword that I can "google/tube" to learn further?

Even if you purchase with a single family home, it’s a start.I’m active duty Air Force with four properties.

It has been about 2 weeks of having it listed on furnished finders, air bnb, booking.com, facebook marketplace, and the MLS. 

I’m active duty Air Force and used my VA loan a few times.You can also check out NACA.com.

In some places you can't put bedroom door locks on unless you are a boarding house, although I am not sure if any one checks that.Another thought is if you don't have central air there some boarding houses that have a monthly air conditioning charge if you put a window unit in. 

And of course another personal Bias is I don't recommend anyone putting training on a CC unless your just looking to get air miles and you pay your cards in full every month..

So my question is if i let the home air out well is it safe?
