Get a new property manager?

[Beverly Gutman]

Hi all! I have a 3 family with tenants in place that my property manager (officially) sent 90 day notices to. (Recently purchased, tenants paying far below market and property very in need of repair) Now, more than 30 days after the notices were mailed I find out the tenants say haven't received them and they weren't sent as certified mail/ legal notice, which basically makes us start 90 days all over again! This is so frustrating, especially since I was told it would be done by a lawyer the first time around! Would you change property manager over such negligence?
