Don't know any realtors in Odessa or Midland. All the Aggies I know are bankers, Petroleum Engineers or own oil companies.
You prefer Odessa over Midland? If you wanted to move to Midland I could help you out with some good realtors.
Personally, I wouldn't buy right now unless I was selling a property to buy another. Real estate prices are way too high. If not selling, I would wait it out, prices will go down when new construction catches up to population growth or drilling activity slows down and people start moving out.
People buying right now are going to lose a ton of their home value when one or both of these things happen. Just my 2 cents.
Good luck.
