Apartment Taking Down My Rent Signs

[Chris G.]

There's an apartment complex where all the units are individually owned however there's a company that owns and manages around 70% of the units as well as work on the property. I manage around 5 units split between 2 buildings. We've been having confusion as the listings online get mixed up with their listings so prospects see their listings first. However the units they rent are around 10% higher rent price then the ones we rent even though the insides are the similar. They have rental signs put around the property advertising so I made some rental signs advertising my units as well however the management company takes mine down. I even spoke to them and they said it's fine I put them up but I guess they don't like competition since my signs show we have cheaper prices. Is there anything anyone should suggest it really just gets annoying since they'll have 30 signs around the property and I put 1 up and it gets taken down and not returned. Makes me want to start taking theirs.
