Hi Nathan, thanks for revisiting, I missed this interesting post the first time through.
I look for a minimum of $100 estimated cash flow using relatively conservative numbers. Actual cash flow has turned out to be higher. I'm investing in B, B- suburbs of Kansas City, in 2019 they are 100-120k properties. They were all done with BRRR, so they have $0-10k of my money still in them except the last two which are held free and clear. 100% of the money I receive from my property manager goes into an account which is used for repairs and further acquisitions. The reserves are in place when needed whether they were considered cash flow or ear marked for maintenance in my original calculations . I got lucky with my timing, entering the market in 2013. Although the mid West is considered a no/low appreciation area I have done very well between the instant equity and actual appreciation.
Estimated cash flow formula: Rent -10% vacancy, -10% maintenance, -10% property management, -principal/interest,-property tax, -insurance.
