I'm very much in the learning stages but have decent financial modeling skills and a MBA which should help me get started.

I just look at every area I go to and evaluate if it works in my model.

I applaud your business model and it's success, keep doing what you do.

Turnkey is really a model that plays well where cash on cash return is good.

We bought for $1,000, out $8,000 into it and that year and model sells for $19,000.  

My main concern about this business model (even though I have a few!)

I'm a hands-on blue collar type landlord thinking about changing my business model to scale up my number of rentals.

One of the examples i modeled out was a 200K @ 1,600 / month in rent.100% financed (50K HELOC + 150K Mortgage @ 4%) my mortgage payments are 1,040.1,600/month in rent gives me net cash flow of 550.

And growth will start to come back into the new construction model again so that the housing model itself returns to normal.Once that occurs, I think comps will start to move up some too and most areas will see their typical appreciation model come back into play.

I like the concept, seems like it can be a very lucrative business model if done correctly.
