I use Donny Thompson of ERA Real Solutions Realty in Columbus. 

They put up one of these devices in a tree near the fence line and problem mostly solved.

If not, you can move to the alternative solutions.

Don't forget to consider API integrations, as many vendors offer solutions that can help streamline your operations.

I have suggested twice that if this tenant is so unhappy with my style of management that perhaps moving out would be the best solution only to be told that I’ll have long since sold the building before they leave.

A monkey with a job and some money in the bank can fall out of a tree one day and decide to be in RE and write a check.

Focusing on the vacancy and if 0% is true or not is just missing the forest for the trees.

Can anyone recommend a good property management software solution that tracks seller financed loans (i.e. properties that we have sold with seller financing), along with tracking the rentals?

While these fees are higher than purchasing another rental property, it's a tradeoff to investing in a passive real estate investment and not having to put more money into capital calls if there were big ticket items needing repairs in a rental.Conner JacksonTangible Wealth Solutions
