A lot of the MHP on the west coast would be what we call institutional grade investments.

If you know the game and are scaling up, I would go straight to a 4/5 bedroom. 2 and especially 3 bedroom homes are the doldrums in most markets.

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. 

Anything that is almost guaranteed to be used daily in your rentals (i.e. couches, bed, chairs), I'd try to invest in as much quality as you can for those specific items.Some store sites will let you filter for "contract grade" or "commercial grade" items - these are the sorts of furnishing that get put into higher-use commercial applications such as hotel lobbies, apartment building amenity spaces, 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 new here, just researching detroit, looking for a neighborhood grade map, and I just so happen to come across this thread, and your comment solidifed the reason why I want to be a part of this community and in particular, helping the single Mommys out there that will cherish the opportunity thru section-8. 

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

I'm looking to develop contractor garages, but ideally those would be slab on grade, so I couldn't do that everywhere without a lot of site costs.I'm new to this space, and looking to also get an idea of developing over fill and what that process looks like.

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).
