It all comes down to area and ROI as to if it makes sense or not but logistically it's a great idea.

I've been mulling over something and wanted to get your take on it.

How much are you qualified to borrow and what will your monthly costs be for mortgage, insurance, taxes???

Constructing new homes and selling them is extremely difficult and challenging.

The LLC will have to sell and buy as much real estate as it sold. 

In my experience, 80-90 percent know nothing and have nothing to say.

you need to talk to your bank and lender about a lot split.

If you think you have average intelligence and a general hard working person, for non luxury STRs (competing with 3 star or below hotels in the area for average people who simply need a bed and a kitchen) I would use 60% occupancy rate to start in the beginning and then 80% after stabilization.

It all depends on the scope of work and your available time to put towards organizing and finding the right contractors. 

Just use the built in tools and go from there.
