I have not been able to find any in person networking events in my area doing a basic internet search.

Renegotiating some utility contracts (garbage and removing some on site office paid internet/phone bills) 5.

With a 4-unit building, that’s a very high customer concentration.

A pool, a small gym, parking, internet.

On the internet?

You want to focus on markets that work with your plan and also where you have a personal connection with someone, even if you build that on the internet.

I suggest having smart TVs and let them log into their own accounts, preferably with a guest mode so they auto-log out after a certain number of days.For catering to families, I would concentrate on providing amenities like puzzles and games. 

First house in 2021 - no internet to search at that time, remember going to realtor offices and seeing magazines and talking on phone with them about properties available and driving by them as there was no google street view.

*That said* - I agree with @John Underwood as you should be concentrating on saving and owning investments, not attempting to create a middleman job.
