Deed restrictions and mobile home parks

[Marilyn A.]

I wanted to ask if there is any way to have a deed restriction changed? I'm guessing that there isn't.
The reason I'm asking is that I would like to own an RV park or possibly a mobile home park. My sister and her husband have wanted to own an RV park for several years, too.
Today my siser & I went to look at a MH park for sale. It's 10 spaces on one acre for $85,000 (just reduced for $99,000). To me that sounded like too many spaces for one acre.
When we got there we were stunned to see the condition of the place. There were 8 burned down MHs there (the agent had told me they would be). The agent said the owner was in the process of hauling them off. But still, the sight was horrendous.
The spaces were crammed in there very tightly. I guess that's why they all burned down.
The good thing about the place was that it has the water and sewer already with individual meters.
So I was thinking, I live on a 3 1/3 acre piece of land (in a mobile), but we don't even use at least 2 of our acres. We could set up 10 spaces for a lot less than 85,000, I'm pretty sure. We would rather do RV spaces than M/H spaces.
We've thought of this before, but the land we live on is restricted to single family use. I'm not sure why or where deed restrictions come from because we're not in the city limits or in a subdivision.
The land was originally part of A 10 acre piece. We have 2 neighbors that bought part of the piece in the front by the road. But we're very secluded and we have an 800 feet driveway you have to go down to get to our place, so it's tempting to do it anyway. Next door is a rodeo. But could we be sued for that?
Thanks for any help.
