Assuming they're not condos, each land parcel is a fee simple "home site" parcel, therefore the developer still owns 54 properties, which is the majority, and voting rights.

In a simple statement, there is no reason a Lease Option Contract would disqualify you from a future mortgage, if you can afford the future mortgage.To some degree, it sounds like both are wrong.  

They shouldn't charge that much, as it's relatively simple to do. 

The only sale of the house is when the new LLC owner executes the agreed purchase agreement.Joe VilleneuveREcapSystemA2REIC It must be "State specific"...In Florida, you can double close with a simple disclosure form.

I would think it could be as simple as knocking on the door offering $500 for them to move , to saying I now own the property and you will need to vacate to filing an unlawful detainer action against occupant and have sheriff evict.

I'm with @Ali Boone, keep it as simple as possible.  

Simple

I'd stick with that $50k-$75k post war built simple ranch home that can be a first time home buyer home in the future if you ever want to sell.
