Hey Domenick! My wife and I did a really fun BRRRRRRRR here in Albuquerque. It may not be the typical style of BRRR but it falls into the category. I think.
So, the story goes like this... We bought it as a SFH, knowing the zoning allowed for additional units. We had a wild idea and built an additional unit from the ground up. Now, we did also remodel the main house as part of it so it falls into the "rehab" part of the BRRR, but I realize thats not really the way its done. We subsequently refinanced the property and have since rented them on AirBnB and VRBO. So maybe we should call mine a BRRAirBnB? :) Ha Ha Ha
The biggest difficulty we had was that though the property had been re-zoned, the neighbors in Nob Hill hate change. HATE. Very slow downward decline, they can handle. That's change they can deal with. Quick, upward, investment and development? HATE. I'm not bitter, I am not bitter. I'm really not bitter. Ha Ha Ha!
I used the Waterstone Mortgage - Chris Russo for my refinance and they brokered a great deal.
The actual rehab part of the main house was the typical cosmetics. Paint, flooring, kitchen, bathroom.
Would love to help answer any other questions you have! Let know!
