Quote from @Aja Sellers: Quote from @Cole Bossert: Don’t settle for an unresponsive PM—especially if you’re remote.

Customer service is unresponsive.  

A slow or unresponsive manager can create unnecessary stress and delays, especially during tenant or maintenance issues.

I am not saying every sales agent is influsnced by this, the best ones understand the importance of brokerage relationships and will not want to hurt their reputation within the community by having  word spread that they are being unresponsive and then the MLS shows the dual agent settlement but there are instances when this happens. 

They have been completely unresponsive, and as a result, we’ve had three vacant units for several months (though I’m unsure of the exact timeline, as I handle the finances and have been kept in the dark).

Once my oldest daughter got there, she found her sister unresponsive and called 911.

If they continue being unresponsive, terminate the contract.🔄 Secure Important Documents – Get copies of all lease agreements, tenant contacts, maintenance records, and security deposit details before cutting ties.🔍 Find a New Property Manager – Look for a local firm with good reviews and ask about how they handle city compliance issues.

Yeah I was planing on visiting myself, and yes one of the complaints I hear many people make is about their unresponsiveness, I've been looking for alternatives as well like you have but ultimately when it comes to quicker steel modular builds it seems they are reigning in that department locally.

Unresponsive customer service leads to not reaching out to Obie again in the future for other rental acquisitions.
