Given the state of the economy, it's natural for people to have a negative outlook on the real estate market. Many experts do believe that we haven't seen the end of the downturn yet, but if you're in a position to sell your property, I certainly hope this agent explained the benefits you will reap on the "buy" side when you purchase.
Right now, supply outweighs demand and with so many jobs being eliminated, downsized and lost on a daily basis, it's easy to see the glass as half empty. That being said, it's important to see the market for what it is; to understand it in your area and to accept what the market says your home is currently valued at.
Every market in the Cleveland metro area is different and in your area, if houses are selling and if you're willing to sell your home in the price range that is comparable to recent sales of homes similar to your own, then by all means sell! You will find yourself in a position to possibly purchase more home at a very reasonable price when you buy. I see this as a positive thing!
At some point, the market will start to creep back up. No one knows for sure when that will happen, but when you buy and the market levels off, you may just find yourself pleasantly surprised to see the value of your new home is worth more than you had anticipated.
On another note, if that's the one thing you remember most about the agent you interviewed; perhaps you should consider hiring another agent. I'm thinking they didn't make a positive impression on you, which may be reflected in your home selling experience.
