Many people like to move up in scale to paid marketing.

Is there any flaw in this strategy (other than speed of scale?) 

@Omar Abdelbadie In my experience, the investors I work with that have automated or unattended stores have more than one location, seems to be an economies of scale type thing.If you do go with fully self-serve you'll need to invest into security and put time into teaching the attendants.

Its also not sustainable if you want to scale and want to become an investorWhen picking contractors dont always pick the cheapest guy and pay attention to everything.

Think it will take some time to achieve the critical mass needed to scale.

Some projects scale pretty well if your family is looking to pitch in. 

As I immersed myself in the single-family space I quickly realized that I was unable to scale to the degree that I would like.

I sold off my condos because my multifamily investments have a better run and more scale. 

IF both of these go to closing (and there is still a whole bunch of DD to be done and financing to be finalized), that would put me at 49 "units", and get leave me 1 unit shy of my goal.Both deals have some shaky areas that will need to be explored heavily during DD; I'll post with updates.So, on a scale of 1-10, I would give myself about a 6 or so with respect to my commitment to doggedly pursuing my multi-family goal, but I'm hoping when I update this post in a month or so, I can say it's more like a 7 or 8 :)

I'd invest it into 4-5 airbnb properties using the Airbnb Arbitrage model with other people's properties and then scale from the cashflow going forward.
