Brick and morter are construction materials that breathe. By paintint them, you essentially seal them. This will cause them to crack and degrade. Geesh, I would wonder a little why you would buy a brick home, then paint it. Assuming it was a good deal, like Henry said, it will definitely affect resale. And your good deal got worst. FWIW, 6 years ago when my wife and I were home shopping, we saw a nice 40 year old home whose brick was painted white. Nice neighborhood, good school district, and all that. But they painted the brick. We were looking for a good deal like everyone but not one I couldn't change.
Anyway, 'nough said. My best to ya and hope this helps.
