I hate to waste people's money if the first person in line checks out and rents the place (causing issue for other families paying the $55 per adult and waiting to find out if they are selected then discovering they are not getting the place).I don't know if I'm asking that question correctly but I hope you catch my drift.Thank you!

A place for an elderly parent or young adult child?

Many times there are 2 (or more adults) so each would be paying that fee.

I’m not a novice at starting and owning businesses, as I’ve been self-employed most of my adult life.

Facilitate conversation and get people to talk like adults.3.

The other secret is to treat them like adults not kids.

From what I’m reading that sounds like no more than 3 unrelated adults?

Put all the adults on the lease so that they're all responsible for the rent being paid. 

The remaining 3 units are occupied by the owners, the owners adult child reserves another unit and the 3rd is basically storage.I'm thinking long game here, but how/where do you start the approach?
