They are full size and yet still run off 120v and just need a water source and drain. 

When January comes, you will have two disadvantages:- you will have missed on the end-of-year planning opportunities- some of the most highly sought after professionals will be full and not taking clients anymoreAnd the longer you wait, the fewer choices you will have.

WE did this for go zone tax bene's  which worked well in those years.but the issue comes that keeping nice bigger new homes in great shape just cost more than little rental dingers.. and in fact as i sold them off I had to do 10 to 20k of cap ex on each one to get full market price.. 

If the numbers don't work with it then don't force it and don't rush it.Always ask for full or partial owner financing the answer will sometimes surprise you.We just bought a property with 5k down and owner financing the rest at zero percent.

There is nothing about how long you need to occupy the property for.So unless our lender puts a demand on us I see no problems legally in occupying each property for any amount of time to fulfill the requirement, then rinse and repeating this process up to our full entitlements, so long as the lender is willing to keep giving us loans.
