Great that you're thinking ahead for your parents! 100k hmmm in Tracy that would not surprise me to be a low price that is meant to drive visitors to see the "under valued" home and bid the price up...a common practice today. I am not versed in Tracy real estate, and don't think that that is a realistic selling price but rather a low asking price. Look around. Stockton and Manteca would offer better values and not far from Tracy. Manteca would be closer and probably better, neighborhood to neighborhood.
Fixers are difficult as "As is" sales require work to be completed prior to purchase and that can be a deal breaker. If I can be of assistance give me a call. Check out our website!
