Also, I think in Washington it's illegal to manage a property for money unless it's for a related party.

If Bernie or any of those idiots pull it off, then T minus 3 years we will be will be very deep into a depression  (it will be like a Jimmy Carter economy on steroids) then that $250,000 cash (if you can keep the "labor" parties hands off it) could set you for life

You could also leverage the potential health risks associated with a dirty unit, vermin, fire hazards, etc, etc.Having said that I'm sorry to see your property being run down like this, I hope you find a solution that works for both parties.

If so, was it provided by a third party.

The property management company was the party that arranged for certain repairs to be completed per the VA appraisal.

Maybe from a builders association or rental association, or just individual landlords as interested parties joining together as a formal cooperative to manage their properties, provide shared resources, screen tenants and mitigate issues among other things?

For starters it's illegal in almost all 50 states to manage property 3rd party without being licensed.

For example, if you can define the data points that you want to capture (location, age, property type, etc.) and ask BP members to share that then you could aggregate it and create value by offering the aggregate data, via a subscription to other interested parties.
