We are on well and septic and know a lot about those factors, but having never developed a large tract of land before, I still have lots of questions about improving the land, adding roads, partnering with builders, and the big issue; bankrolling this thing.

If you want a 400 space park on the FL coast, you'll need to have broker/seller connections, a proven track record, and a bank role/investors. 

And I don't have a high bank roll, or access to a breadth of private lenders (my track record isn't there yet).  

Acquired flips during down turn economy, did most work myself on days off, built a bank roll then started holding acquisitions.

Seller gets more money, you get a lower rate, and if you bank roll he income from the property pay it off early to save more.

If you know what your bank roll is up front, you can work to work backwards and find your deal. 

Looking to keep working & use that income to build up a bank roll for multiple properties.  

Looking at your question, and your possible bank roll, I think you're likely to end up doing a mix of both, don't you?

If you want to invest you will need, earnest money, down payment money, home inspection money, fix up money, closing cost money, 1st years insurances and taxes money, operating reserves money (as specified by your lender and your own personal analysis).If you have the dough, there's plenty of go, but without it--you have nothing to invest.Will your 60k (60G's in old time movie talk) be enough to bankroll this investment, or will you need to add to that?

Not because I am in the market yet (I'm still learning the basic principals of this business, putting together a bank roll and a team, etc.), but because I've never done it before.
