I would agree that there is the benefit of scalability and the price/rent ratios are definitely more preferable for Multis, especially in the Springs. 

Even though I've been able able to scale at a good pace and cash flow strongly, I think that I could have had much larger gains and more scalability with his method.

A system should be easy to understand and scalable.

We're looking for some small multifamily in the Abilene area now to be a bit more scalable.

Although scalability is a problem.I have a few questions about the process though.I hear nothing but good things about Memphis Invest so I would probably go with them first.This is probably a dumb question but I want to be sure, if I get approved for a mortgage for a property offered by a turnkey company such as Memphis Invest, the monthly mortgage is included in the pre-ROI analysis right?

There's the 1-in-a-____ chance you'll find it but it's not an easy, scalable model for someone seeking to skew passive on the investor spectrum.  

(cold calling is scalable but deal with the upset people is a headache, way worse than the upset people that get post cards)As @Jay Hinrichs mentioned people hate it even more than getting a postcard. 

Then my model is scalable.

After making my first buy and hold purchase and having all that capital tied up in the down payment I have turned to BRRRR to move to a more scalable process. 

I also want at least two years of living expenses in savings accounts insured by the FDIC or NCUA.I have $2,500 a month of living expenses (frugal lifestyle), but the formula is scalable to whatever lifestyle you want to engineer for yourself.Some derive their investment income from index funds, others use income property, and others mix and match their investment income from a variety of sources.
