What other methods should I use to acquire another property? 

I started by building a 12-door portfolio using the BRRRR method and self-managing initially.

I have used this method in the past and 90% of time has worked, perhaps I was just lucky, I'm not an attorney but based my thoughts on common sense and what I have read. 

BRRRR method is also a great way to go - good luck!  

I think this is the method I would like to go as it fits in line with what I envisioned. 

Used houses in the area sell anywhere from $75-125 a square foot.These are long term rentals that I do not plan to sell.I am reading the Rental Property Investing book and implementing the method that focuses on cash flow and that strategy states you need to have $300 cash flow per month, per property.

Well, not long ago somebody made a post about BRRR not being a good method at this point. 

Brandon Turner outlined this method in one of the older podcasts and there are previous posts in the forums.  

Under this method each investor has ownership and voting rights.

It should only take a few months using that method...
