I have bought a couple of units and now working on my own development.

They are billed as "a scientific approach to single-family rentals" and use "institutional grade property management," which usually means they are a tech company in real estate and likely either don't have the existing property management relationships in each area or you chose an area where they don't have enough units through Roofstock for the PM they chose to care.

Regulation will say you have to be registered and pay hotel occupancy taxes, but your unit may not qualify for registration. 

You've earned $132,000 more by splitting your money and leveraging it.Since I've been searching for more deals I have seen one or two that might actually cash flow decently but most seem to be at break even assuming normal expenses, vacancies, etc.I'm just learning my comfort levels with leveraging and trying to take advice from others about managing multiple low cash flow properties vs. one higher value one. 

Given how the housing authority does their rent price determination on individual units, and government ran programs are never beacons of efficient processes, it can go either way.Note, the examples I speak of only relate to C-Class and below areas.

@Christopher Mooney - I house-hack a 2 Unit Building in Bayridge Brooklyn which is a 45 minute subway ride to Manhattan Wall Street Financial District (a 7 mile drive).

Adding small units in small unit counts is expensive development.  

For example for a few holes in the walls they have someone paint an entire unit and take their spread.

I think behind tenant screenings and leases there is a quality of a landlord that's also as a person that is the respect for a good person and the intelligence of making fair affairs.For me for ten years in the past I had a house of 650sqft (two rooms and cozy kitchen) where I always have been giving away one of the room for others who were asking for help for themselves and I didn't had any earnings for me by that, and that has been during for many and many years, meanwhile I was surely needing more space for me, for my business in a studio and for my own personal life I eventually could have been having.Nonetheless this, on last years I had no more an house and I needed a room for rent, but even before any screening the landlords were being unrespectful and very unreasonably severe to me, they often had making me lose so much time by no taking or going away to the point I had no other choices in the end, and they set me in the wrong places for me, dangerous ones, too small, too big and very expensive, unhealthy ones or not providing anything at all when it was obvious they needed to.To me this kind of behaviour is very wrong, mostly because usually they are the same people who pretend respects and acts as they are very careful and attentive to housing situations in general, but with me, they have been lying above anything and just disrespected the person at a human level. 

Both units are approximately 400 sqft, "yurt-style" cabins with large decks.
