@Michael WagnerAlso, have you ever thought about motor home parks?

The one other thing we do is we replace all hinges with invisible hinges; You can buy "non-morticed" invisibile hinges and add blocking to mount on the older style face frame cabinets we often find used.

Then focus on Charleston, Mount Pleasant, Sullivan's Island or Isle of Palms.Check the local STR laws.

Should I hire a professional TV mount installer and send them a quote?

The little motors on the windows give out quickly and so they won't work. 

Tenants are going to get satellite, because they must have their 120 channels and dish is cheaper than cable.You know they are going to do it, so provide a location for the dish and show it to the tenant and make them sign something that says the satellite dish will be mounted only on the pole that you have provided for it.

The minute your contractor falls behind and realizes his losses will mount by the day, he’ll walk.

I had a scary situation happen to me once right along these lines… (And I have a fair mount of experience).

He did a very high end flip including a swimming pool complete with fiberoptic lighting, Brazilian hardwood floors, Carrerra marble kitchen counters, above mount bathroom sinks, top of the line appliances, flat panel wall mounted TVs.

A motor spins the base which turns the cable.There are smaller, hand or drill powered versions.If all the drains in the house are slow, you'll need to find the main cleanout or cleanouts.
