Attached is a link and I really appreciate any input.Thanks so much!

Just a stray thought.When it is attached to a new foundation it is real property again.Two useless thoughts in one day.

@Molly Morlino if you built a permanently attached building to someone else's land then technically they own that property. 

I've attached a pic with some details on the HomeStyle loan.

So their attachment to the property is clearly very strong.

You should be able to find a simple interest calculators online that will show you the result of doing it this way.Not all lenders provide this; some attach a checking account and you would then manually/electronically transfer your income into the HELOC and the monthly expenses out of the HELOC into the checking account in order to pay expenses (this is referred to as a 'sweep account' to use their banking terms).

A community pool area will be attached..... 

Please see attached Flip Calculator infor.
