I am going through this with a current property that the PM failed to communicate had issues.

While I am about to provide a 3 day notice to a tenant that I communicate with regularly and whom I've worked with for 2 years, is there anything I can or should do to fix this now or does it not matter?

Consistency in guest communication, being out of state and unable to be hands on, nuances that come up that you were completely unaware of and you don't have strong boots on the ground - all good reason to be passive in this business.

I've searched the forums here and also looked a bit through Google searches and haven't seen a lot of people post about call centers or VAs that they trust to handle this task.I've looked into Call Porter, Patlive, Map Communications and several others.

Maybe they communicate differently but have good intentions.

I do self managing, but I’m doing 6 units and I’m doing them locally, so it made sense for me to learn the business and try to be as efficient and profitable as possible.

Offer to also be an advocate for both parties to assure the landlords, (if that is possible, I don't know, not really my space) that they will be able to have open communication with potential tenant.

I would check to see if they left without communicating.

Landlords that don't understand how to clearly communicate and document things can create a lot of problems.

That means you may be showing the property, helping with application screening, collecting rent, inspections, maintenance coordination, lease signing/renewals, owner communication, etc.
