There are two real estate companies in the area that I would suggest that you call and let them tell you what has sold in that area in the past year to see exactly what the market trends look like. One is Coldwell Banker United Realtors in Angleton Office at (800) 355-9455 and Will Clark Real Estate at (979) 849-1101. These are two very reputable offices in the area. ONE OTHER THING to be sure and ask each of these or anyone else you might decide to check with is "DOES THIS AREA FLOOD?" Watch out of that in most areas around Rosharon.
Good luck and God Bless.
