Depending on how much you are looking to get for this name. If that would be me, I'd renew.
I had a recent case when someone offered me SpainTravel.org (I run a travel agency in Spain, so I got this through agency mail). The offer was around $1200, but I refused. But for like $300 I would buy it to redirect to my site.
HoustonProperties is a larger name (industry is more ''money'', heavier packed clients), and I would price it somewhere high $$$. I think you'll have a good chance with it. IMO.
