Do yourself a favor and don't look for the easy way to find out the value for your most valuable asset. Spend the time and money to do it right. I'm sure you should have no problem finding a realtor in Corpus that can give you several appraiser referrals. If your simply curious about the value, ask your realtor. If you don't have one, get one. I assume you have a doctor and a dentist....you should have a realtor.
