Leverage will be based on whether the land is entitled and borrower track record but 50-60% is the norm, not 80%.

I would like to purchase a structured course and have narrowed down my options to Seth William's REtipster masterclass, Joe McCall's simple land flips course, and Jack Bosch's Land Profit Generator.

If you own the business and the land, I would keep them together.

From my research you cannot sell the mobile home without it being paid off since the land is financed with the home.

I am looking to buy a lots / land in O' Fallon , Missouri .

If you think land flipping is for you, there are plenty of decent paid options out there. 

I never choose anything based on price.

Been listed for 5 months for sale, but it's is a land lease now with 29 years left.

The price paid is well below what we should have paid based on number of lots/homes/ that can be built.

However, since I am hoping to sell the land first.
