Cold calling is only one marketing method.  

But hey its money whether its a living is another matter For the future I am switching to the buy it off the market and put it on the MLS with a realtor method.

I would consider doing vanilla long-term rentals, but I think I want to do the BRRRR method, as scaling will be a challenge for me without it, I feel.

Hey Chad, there are different methods of appraisal.

You listed two but in broader terms financing (assumable, owner financed, sub to, fha, new 95% OO LTV that in most ways is superior to FHA, dscr, F/f conventional, NACA, VA, etc), value adds (development including ADU, upzoning, traditional rehab, sophisticated value adds that leverage localized rules, coop/tic, etc),  property types (residential, commercial residential, land, storage, MHP, industrial, office, camping, hotel/motel, etc), passive/active investment methods (GP, LP, REIT, nnn, self managed, pm, flipping, mineral right, lumber rights, etc), residential rent models (LTR, STR, MTR, rent by room, student housing, arbitrage, etc).  

Hello Jack, in Texas I find a lot of investors using the Subject 2 method, especially with FHA properties where they are at or under water on their mortgage, but most of the mortgage rates are under 4%.

To make the most of this opportunity, I'd love to hear advice on promising emerging cities to focus on, the advantages and disadvantages of each, and alternative financing methods beyond traditional mortgages

The seminal book on the strategy, 30-Day Stay, published here on BiggerPockets and written by MTR pioneering investors Sarah Weaver and Zeona McIntyre, has helped popularize the method.
