I like the concept of a Real Estate Line of Credit but I found with FAO commercial that what's on the surface doesn't translate.

Hotter than the surface of the sun in the summer.Insulation is one of the least expensive ways to help this situation out - you can even rent a cellulose blower at Lowe's or Home Depot for free if you buy 20 bats of insulation. 

On the surface it looks like little risk, but doing it the wrong way can have pretty severe consequences and come at times you least need those consequences.  

@David Clay yeah it is pretty irritating.

On the opposite side of the lot, I would do surface parking spaces. 

@Clay Manship I'm especially interested in how you overcame the first hurdles of using this strategy in your area!

Meet with investors and make a list of where they are buying (usually the same areas will continuously surface) and also make connections (find YOUR buyers there!!)

Once I discovered from a friendly corner conversation that the neighborhood was built during the post-WWII metal shortage and all the sewer pipes were made from clay.

I haven't used it in a rental, but one floor I really like is the floating stuff from Fusion. 2/3 of my basement has their 12x24 "slate" tiles - they look nice, and whatever that surface is made out of is diamond hard.
