My day job is a scientist, so I just applied the same concepts.

As a real estate investor, you should generally purchase properties under an LLC to protect your personal assets from liability related to the investment, while buying in your name may seem simpler and potentially cheaper (in the savings on interest) but exposes your personal wealth to financial and legal risks.

As a general rule, the lower the down payment, a person invest on the buy then the easier it is for them to walk away from the property, especially if it will not show up negatively on their credit.A person would definitely have to tweak his program/teaching for their local setting. as others have said this is not a new concept. however, he did seem to package what he’s doing in his location in a way that I think can be understood.

I am near Pittsburgh and am interested in this concept.

The concepts of wealthy and poor are personal decisions.

Anyone who mass teaches a concept and gives you the impression that it is acceptable everywhere, is "blowing smoke" to collect membership fees.

@Yakir Aloni the entire concept of the BRRRR Method is so that you don't have a downpayment.  

The market is still affordable enough to find properties in the $120K–180K range that hit the 1% rule and cash flow from day one, plus it’s very landlord-friendly, making property management a lot simpler, even for out-of-state investors.

Sometimes I think of the differences between Microsoft Word (which has EVERYTHING but you might not use it all) and Google Docs (simpler, has the basics, but not all the extra stuff).

Get it rent-ready, since tenants rarely notice the small flaws that owners do.Because you qualify for a VA loan, moving into a simpler home while keeping your first property as a rental could give you both income and a fresh start.In the end, it comes down to your priorities.
