The Brock Hills homes are beautiful. Yes, they do have foundation problems. Not all, but most. You can easily see them in the sidewalks leading to the houses, garages, patios, and other areas. The issue is not the foundations per se; it is the hillside itself.
Rumors abound, don't they? So far, the homes are still standing and the rumors have not come to pass. Anytime you purchase a hillside property, you want to see if there is any current information with regard to hillside stability. There will always be rumors!
Please make sure you get your information from a LOCAL realtor. The homeowners association has no information to give you in this. They are there to collect the $$ for commen area maintenance. Good luck, and if you decide to purchase a Ventura property, please call me - a VENTURA realtor!
