BTW - AirBNB is a platform where you list your Short Term Rental.

that is more a RV park. the MBH parks down here. we typically own the land, lot, and trailers. there is a reason but long story short, if i just own the lot and they dont pay the fee. i do not have the biggest teeth to push the need for my money. but if i own it all, my experience says it is a better path

Congratulations on your impressive success since 2021—that's quite an achievement to have closed over 100 transactions in such a short time.

.- If you're going after a seller finance deal I think once you understand what it will take to get to a finished state its simply a matter of aligning your needs as far as short term cashflow with the current rents/situation, with the net number the seller needs after the refinance.  

What I'm wondering is: is there a way to get the cash invested into this rehab back out of the property in a relatively short timeline, as if it were a BRRRR?

Start by leveraging what you already have—consider tapping into equity through a HELOC, house hacking again with an FHA loan, or increasing cash flow by converting a unit to a short-term rental.

In short, having all the conversations and commitments in strategy, setting up LLC and all the fun docs of who's doing what, and I'd suggest even getting initial funding into account for at least EM. 

Short term it is difficult to make the numbers work, the cost of new construction and the time it takes to zone-plan-build are usually the main reasons why private investors stay clear.

I know many successful people in this business - some have invested $$ in their education, and some have not.While it is a very short list in my opinion, there are a few good "gurus" out there who teach because they enjoy it firstly; getting paid is secondary to them.

Limited labor and resources : Unlike the catastrophic fires in Lahaina Hawaii there are significant resources in Los Angeles to contribute to recover, but quality contractors, tradesman, plumbers, electricians and laborers have long been in short supply.
