Does having 2 full R.V hookups on property increase the Value of the place.?

You need to check the zoning - it may be illegal to use these hookups. The mobile home may also be illegal. It could be grandfathered meaning it was there before the law changed so it can stay until the property is sold. Your deal of the century could be the biggest mistake in your life if you do not have everything in black and white ( written). You may not even be allowed to live in the house, but the town will allow you to pay the taxes on it!
