I have heard that a good rule of thumb for a quick land sales flip is to price it for sale at half the rate of comparable land, while making double your money.So, with that being said, I would research demand and land prices for comps on a popular land website like landwatch.com. 

@Tom Gimer  just like buying with Auction . com once you have an accepted offer you CANNOT change vestings even though I have bought ( well lets say a bunch of them off of this site) I have to follow the rules and I don't like it because I like to change entities occasionally as funds clear up in one LLC... 

The other restriction is that you cannot have another 203B/K (only one at a time).So, you should be able to do a 203B, as long as you owner occupy the 4 unit.Good LuckJim

Does anyone know if Banks & Mortgage companies have stricter rules now a-days regarding lending out equity loans and HELOCS.

Michael, it depends upon a lot of factors.For people involved with REI, it depends upon what you want to do with the business as there are different tax rules based on type of entity.For holding rentals, I generally recommend an LLC if you are setting up an entity at all.For flipping and development, I generally recommend an S corp.For wholesaling, my recommendation would depend more upon your specific business.

how come nobody explains the breakdown of the actual 70% rule??

So basically there first rule is that you can't have a property under contract and use there funding. 

I understand if you want to sell your restaurant and want to exchange for an apartment etc there will be some restriction.

Perhaps region specific "de facto" rule !!!

This is NOT a hard and fast rule but the odds are in your favor there.The winterizing crews they use don't bother to check the system BEFORE they winterize.
