Using an agent to find a tenant in an adult community vs advertising online?

[Gil Lieblich]

I purchased a couple of units for what i consider a good price in an adult community in boca raton florida. I live in NJ so i was shocked to find out how much the agent wants to handle finding tenants for my units. My issue is apparently tenants use agencies to locate rentals for them so basically i have to pay a commission to my agent and the agent who brings in the tenant. I attempte dto list initially on craigslist but got no responses. Is it the older poeple feel more comfortable with an agent? are there other resources to post thatt would attract the right tenant?
I think my agent screwed me as we priced the rental to high (right on the numbers she said we could get when i bought the place) now she claims that no one gets those prices... basically keeps blowing smoke up my you know what.... but they are the main agency that handles the development so i feel stuck with them... After lots of negotiating i got them 'down' to 13% commission.
