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. 

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

I am concentrated in the land development sector and multifamily.

But after an exchange - sign the purchase documents with one pen and pick up another pen to sign the refi docs :)Another strategy you could consider is reinvesting into multiple properties, where you purchase the first property cash (ensures some security and concentrates the equity) and the second property with a mortgage.

@Randall King If you find the property isn't performing well, a 1031 exchange would defer the tax and concentrate that equity into something that has a greater cash flow potential, like what @Corby Goade said.

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

We have concentrated our portfolio even more into a 20 minute radius.

Concentrate on increasing your earnings rather than on not paying off your debts.

This could allow you to concentrate your equity in one purchase by doing it in cash.

I read Brian Burke’s book and concluded I wanted to go with a syndicator who was vertically integrated in all phases and also geographically concentrated such that they were experts in one  location.
