All the variables are generally the same as with the 10-unit that you just closed, same age building, same quality build, similar square footage per unit, obviously same localities.

What other methods of contact do you use besides "cold calling" to buyers and Landlords?

Which brings me to my ultimate point.The BRRRR method is dependent on many factors, but the single most important factor is the rent you can achieve.

I'm most concerned about tenant quality...I don't want to be concerned about crime, evictions, rent delinquency, etc..

If I'm understanding this method correctly you basically have to keep investing otherwise you're going to be stuck with a loan at 75% of the house for 30 years?

If I understand the Refinance piece of the BRRRR Method correctly...

The quality of a rental isn't 100% tied up in this one metric.

Most of the work have to come in the forefront, of course you have to have quality leads and that means you have to be really good in pre screening them, these have to be Hot, or warm, not likely cold, but cold you can follow up on and then once they are warm, pass them on. 

I have been trying to discover a meaningful method to read the areas social structure, economics, etc. 

Can the BRRRR method be applied to small businesses?
