This would likely be a bad investment in your position. 

May your bookings be as plentiful as you wish, your guests be low-maintenance, thoughtful, and honest, and your positive reviews numerous.

Depending on the size of your PM company they may or may not have an internal maintenance position to handle these.

If there were a tech solution that solved the security problem or a human solution (licensees whose sole job was to open doors), that would be a positive, time-saving innovation.Again, for the many'th time, your referencing EXISTING things/business's as-if your planning to "invent" what already exists....... https://showami.com/ 

Plus, you do also put yourself in a position that makes you more liable for a lawsuit if you self manage.  

But an equity position is not recommended unless they own the dirt or bring some other kind of value. 

Any insight, positive or negative, would be immensely helpful.

Seems pretty positive.

Rise up the ranks to a c suite position.
