I am especially interested in learning to master the BRRRR method, but also ready and willing to use traditional methods to build my portfolio.

@Zach Chandler if you are going the self-manage route, which I highly recommend because it’s simple, as @Gerald Pitts mentions, use the Short Term Shop’s ‘Enemy Method’.

By keeping borrowers informed at every stage, this method helps avoid misconceptions.  

Just keep in mind this is a typically one and done type of financing as it requires owner occupancy.Neighborhood quality is crucial and cannot be overstated.

This took away the LL capability to not renew lease or, my preferred method, provide large rent increase above market to get rid of less than ideal tenants.  

We manage a lot of properties in C class areas, there is money to be made, but you need a quality asset,  a great screening system, and you need to be able to realistically quantify the risk. 

As to your points about other methods such as 'investing in a private syndication' or the like imagine this; you can invest say 500K cash and make a 500K return over 5 years that you now owe say 200K in taxes on leaving you with 300K profit - *or* you could invest 500K from your ROTH IRA or SOLO, make a 500K return and owe NO taxes and net 500K profit - a 66% better return.

If you contact zillow through a bunch of ways (they also have social media outlets where you can comment, and that's what we did, in addition to all the other methods of contacting them) my understanding is they eventually do get back to you and are reasonable in resolving matters. 

There's also a very underappreciated fund that will be a distant 4th but likely the best of quality.

We prefer to handle this because tenants often don’t find high-quality replacements on their own.In our market, we usually need a 30-60 day notice prior to move-out to fill the unit.
