To be efficiently with my limited funds I have to brrrr so I can scale and use all the cash flow and attack one property at a time.

I'm not like most people on BP in that I think that the REI market is pretty darn efficient. 

If I do find someone who is reliable and worked efficiently in my first deal, I'll make sure to relay them to you!

I would like for a contractor to just build a shell, maybe out of cinder block if that’s the cheapest but efficient method.

I had a few small properties with repair issues, and one year I was down there every other week spending half days patching holes in the walls after plumbing repairs because it was not cost efficient to hire someone to patch small holes. 

They spend on fluff that has no bearing on rental rates or spend extra on efficiency upgrades when utilities are in tenants name.

The heating system is not sized big enough and the unit is not efficient.

With this in mind, it's been my experience that passive direct mail to a purchased leads list is the most cost effective, time-efficient way to find and nail down these deals.Just try to find deals like this on FCI exchange.

The units are only about 80% efficient at most but they work without electric power which is nice.
