What other methods should I use to acquire another property?

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.

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

An LLC is potentially one minor factor that might contribute to the evidence that you are running your rental activity as a trade or business, but it's definitely not required that you have an LLC to qualify.

In place of a flat fee I can see the transition being something based on referral (did my buyer agent get me a trades person, lender, home inspector, etc.
