Building small units in small counts is expensive development.  

And they execute their investment strategy/model (develop, resell, hold, etc.) effectively to generate a return and/or equity and make a living.

If you decide to go the multifamily route, Real Estate lab .com is a multifamily software for deal analysis plus they have many other useful features. 

If I have to manage the property by myself, I am curious which property management software (Hostaway, Guesty, Lodgify, PriceLabs, Hospitable) is better for sending check-in, checkout messages, and other automated messages.

I am also a project manager and a architectural designer for a real estate developer in NYC. 

Thanks as always.RL Local PM here, we develop and have a wide portfolio, happy to model a cashflow analysis and if possible, find ways to increase your properties income.

I have experience in single family fix and flip, 1-4 family rentals, small apartments (10-30 unit), 100+ unit apartments, development, commercial retail, industrial and office.

We have no interest in contact data gathering, as that space has been well developed. 

@Rosmery ThenMy partner and I are in the same situation, just he has 20 years of construction and development experience.

In our student houses we use a programmable thermostat, but our building monitoring system has its own sensors and can override the wall thermostat and will not allow the temperature to get below 10C (50F) ... we are presently testing a new software load that will also prevent them from cooling the house too far in the summer.
