Need experienced opinion on my business card please

[Sean Gallagher]

Front side simple to the point, name of business, my name, and contact info with a nice graphic/background. Back I want to use for detail. I have

Prosperous Properties, LLC specializes in buying & selling real estate. We close fast and work hard to make sure both parties are satisfied at the end of a deal.

Is that usable? Is it too much? I figured a simple business message would be adequate here. I guess I could list buy & sell but that seems too plain. Do you suggest I have one card that shows I buy real estate and then another that shows I sell real estate. For instance a card I would give to a home owner who is looking to sell and then a separate card I would give to a rehabber working on a home showing that I sell property. I think what I have works for both and would be ok. Thanks for all opinions and suggestions.
