I understand that BRRRR would provide more cash flow, but from what I've read this method also requires more time and investment.

I am in Huntsville, voted #1 place to live by several publications such as Kiplinger's and USA Today.

You need to set a deadline for them to correct the issue, then follow up with an inspection or other method to confirm compliance.

If LL uses accrual method, they can book revenue without receiving.  

Strategies like house hacking, the BRRRR method, and long-term rentals have worked well for me.

Sorry for the questions just curious about your method since it seems different than most.  

Given your situation, one strategy that could work really well for you is the BRRRR method (Buy, Rehab, Rent, Refinance, Repeat). 

There is literally TRILLIONS in votes on this, because that's what it is the people are doing with there buy/sell $, there voting for who, what, how they want the service. 0-guess work needed, we have all the data and facts at hand. 

I wish there were a down-vote button for this idea.

that was not a method that Armando taught in the seminars I attended these were strickly how to find BRRR props and rehab them and then resell or refi and keep.. the Markets we worked were Vegas and Orlando and Frankly those investors who actually bought property doubled their money or more with the deals i funded for them and they bought on their own it was 2011 to 2013 which as we know was a prime buying time and had to hand it to Armando he picked two of the best Markets..
