@Kyle Scofield :: my A-1 they-have-a-mortgage strategy is installment land contract.  

If you owned the land, you could use that, otherwise its cash.  

If you overpay your cashflow will be in jeopardy and you will not be able to refi to pull out moneyAlways buy on actual numbersYou learned more on one deal than most investors learn in 5 yearsYou will land a deal soonStay motivated and on the lookoutGino

@Chase London  I have funded a bunch of this stuff in Chicago land.. nice brick buildings that can be bought for 10 to 30k  the issue is they take 60 to 100k to totally redo.

Instead of rentals you have land.

With that said, I keep separate bank accounts (all my properties are in separate land trust ownership's so different names for each) and am able to transfer back and forth electronically (which is also go for record keeping).

I think a lot of it is they're not building any more oceanfront land.

If you live in an area where the land commands a premium this may be an option, but as @Jack Johnson said how long will it take for you to sell those lots? 

All title companies are regulated by ALTA, American Land Title Association.

Perhaps you can get the land, and move one or more MH's that are in better condition to it.
