Property Manager Not raising rents as requested

[Scott Houin]

About 6 months ago I reached out to my property manager in writing and ask them to raise rents on all my properties by $25. I reminded them to do this about a month before each lease renewed. When I got my lease renewals I was told by the PM rates were not raised due to market conditions. Three out of four of my tenants renewed there leases and I was never notified that they weren't going to renew if we raised rents. I feel they didn't attempt to raise rents and just simply asked them to renew. I also have done a market analysis on the rents in the area via MLS, craigs list and zillow and found that the rents we requested were well within the market.

Should i fire this management team and find a new one?
