Cold calling is only one marketing 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.

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.

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).  

The forum you posted in is about the BRRRR method. 

Are there any practical methods for implementing usage-based billing without submetering?

Hey Chad, there are different methods of appraisal.

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%.

You mentioned $25,000, but you’ll need to spread that over multiple years unless you're using other strategies.Five-Year Rule: The converted amount will need to stay in the Roth for five years before you can withdraw it without penalty.

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.
