I do think a multifamily property with an FHA loan would be better because you could even live in one unit and rent the others out (long-term or short-term depending on local laws), and it is generally more scalable. 

I am also considering the possibility of just using the heloc against my primary as another down payment on a house hack, however at some point I would like more scalability which is why HM intrigues me.

Here our “do things that don’t scale” approach (i.e. our fastidiousness in project planning and execution) did predictably result in outcomes that aren’t scalable due to the pace of renovation.The solution was part of the problem in this case.

They tend to appreciate more; they tend to transact easier (buy and sell), and they have better long-term cash flow per door.That said, the downside to single family is its scalability.

I am not sure if this method is scalable if you are doing this in large numbers but if you are spotting properties while driving around, it is definitely feasible. 

It was a solid deal, but I had a hard time envisioning how it would be scalable. 

Its scalable, versus buying a $400,000 home or $600,000 duplex if your starting out.2. 

Hello all,As we close on our 1st investment property here in Northwest Florida, we are moving our focus to multi family and apartment investments.As much as we'd love to compete in the short-term rental market, we see a big need for local, long-term rentals for the folks living and working here.We wouldn't turn down more opportunities for SFH investments in the area, but we are looking for scalability, and increased cash-flow.Although we might not be ready to invest in the immediate future, we certainly need to lay the groundwork now for building a pipeline and analyzing deals.Open to opportunities for rehab, and development.

Scalability is the name of the game in building substantial, sustainable cash flow over time.
