BRRRR is an amazing strategy to quickly scale and to recycle your capital quickly - it's how I personally got started investing here in Columbus Ohio and quickly grew to over a 7 figure portfolio.

If all you’re concerned about it growth, DSCR loans would help you scale your portfolio without a DTI constraint (let me know if you want more info there).

I can tell you institutional level capital or at least 95% of it wouldn't touch that kind of deal due to economies of scale, risk, population, no access to utilities, etc. urban centers is where we focus. large metro, etc. 

Generally, more units will give better economy of scale.

I am a USMC veteran so I have some flexibility with finance options and I am looking to utilize all resources I can to build and scale my portfolio.

I'm interested in purchasing raw land (or close to raw) to scale up as cash flow permits.

As your business grows, HubSpot scales with you with paid plans offering more advanced features.

But no one that stupid is going to ever get to the point where they are entertaining a 100-unit, so there's no point in trying to market to that person, they don't really exist at that scale (and, to they extent that they do, they aren't falling for real estate scams, they are falling for crypto/nft/blockchain/ai [+ next years buzzword, whatever that is] type scams). 

A 4-unit property is a great way to start and scale fast. 

I agree I can make more per unit with SFR but scaling is tough.
