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.

There is a book in the library called "Low (and no) Money Down" that discusses the various methods of financing purchases.

No other methods of payment accepted, written into the lease.

Are you looking to continue doing the BRRR method or branching out? 

Have you looked into the Turn Key Method?

Quote from @Stuart Udis: ....But I set the goal of acquiring 50 doors in the next 3 years using the BRRRR method and will then be financially free...isn't that a scalable business :)We see the above type comments from not so experienced investors or business owners all the time being posted on BP.  

Seeing a lot of borrowers have success across the country, especially with the BRRRR method and the AirbnBRRRR methods! 

I've been around the block and worked for the money I have so by nature I'm methodical.

Any recommendation for the first steps I should take if I want to purchase my first rental property using the BRRRR method (or flipping).

If you haven't connected with local people in your market there are several methods here.
