Adding whole building wifi for smart devices?

[Mike A.]

I recently took over a small building in a A area, very Ritzy in Stamford, and I am in the process of a small experiment. It's only four units, so it's a controlled test to see if smart devices can raise the rent and save me money at the same time. I am installing:

(4) Nest Hello Doorbells

(4) Nest Protect Smoke alarms

(4) Nest Thermostats E's

(4) Nest × Yale Locks

I will set them myself, as I've been using them in my home w/o issues for over 2 years. I will setup separate accounts for each apt. and when they are rented out, they will be given a login for the Nest account and I will also charge a $25.00 per month, per unit smart home support fee. That includes support and any additional help they need to manage the smart apt. However, I need to figure out how to get wifi for the entire building. It's only four floors, so it shouldn't be too hard, I am just not sure how to do it. Would I just call the cable company to install the Internet?

Open to ideas.

I can tell you, the Nest Thermostats in my home save me about 150 - 200 bucks a month then my previous programmable thermostats. I would think this would be a big selling point for the tenants as well as the alert features they'd have all setup when they move in. With the smart support fee, I'd be able to recoup my costs in less than a year and then it pays for itself. In addition, our utility gives a rebate for the thermostats as well.
