I've been looking around. A really nice sales agent at a co-op mobile home park explained it to me. For the most part banks will not lend you money to you to buy into the co-op. It costs about $28K a share plus the cost of a home. An older home from the 70s can go for as low as $30K. You own a share not the land. You still have an HOA, but even the rates here were great, I think they were only $160 a month. The problem is if something happens to your home you own like it burns to the ground you still own a share and have to keep paying the HOA. To get a new home, they only allow never ones with rules about an elevated enclosed porch, car port, etc that would make it very expensive to put a newer home in. The benefit is that it better than lot rent which is throwing your money away. In this area it's at least $700 so in 4 years you would pay more than the $30K and own nothing, but your costs increase every year. There is a smaller one in that area where you do own the land, but it's not like regular land where you can build a home, you can only place mobile homes there, and you still have to follow HOA rules, but they don't have a pool or amenities so the HOA fees are about $60 a month. Worst is lot rent, Co-ops are a cheaper alternative to live there, owning the land will increase your chance of selling and your buyer getting a loan.
