However if I do a BRRRR I can achieve infinite return by extracting all of my investment.

You can sell your note (aka future cashflow) at a discount or whatever you can negotiate on the open market but that about your only remaining option for extracting cash out of your note.

You see Rina, Rolfe spent three days painting a picture of:1 - The perfect business (high gross margins, high barriers to future competition (quasi local monopolies), increasing demand).2 - Claimed that this perfect business counterintuitively sells for a big discount to its true value - and painted a plausible dual reason for it:a - the stigma premium - mobile homes are yucky and embarassing, therefore demand for them is lower than would be expectedb - the current set of owners of this asset class (mom and pop) are so stupid and lazy that they have priced the rents of the asset class lower than they should be compared to apartments.3 - He then masterfully executed the classic sales technique of creating a sense of urgency - saying that the current fragmentation and irrational discount-to-value of this asset class (mobile home parks) will soon expire because "mom and pop" are dying off, and will be selling out to professional investors with huge pools of capital.4 - He claimed that when this de-fragmentation occurs (the next 10 years) the discount-to-value will disappear and that the real value of the rents of mobile homes will finally be extracted through inevitable professional management.Item number 4, Rolfe must know, makes any experienced investor salivate - it's like cat nip.

I know paying cash upfront allows you to extract that cash on the refi but has anyone done a FinanceRehabRentRefinanceRepeat???

Is it hard to extract value from owning a street?

You seem like a nickel and dimer who is trying to extract every last penny from the deal.

It's a bit of a game - find the cards that offer the most value for your situation, extract all you can from them, and be prepared to dump them for a better offer if one comes along.

@Dave Foster thanks for the reply, my goal is to delever my current portfolio, by extracting equity from my current house at a given interest rate to arbitrage business interest rate will not serve that purpose though it would help with overall cash-flow midly. 

It more than pays for $250k each costs....so this investor extracts his original $250k, able to "repeat" and buy four more in the next year....and could actually have $50k extra profit in his pocket.
