It depends on if there has been a lot of distressed sales in your neighborhood. If this is the only one, and all of the other recent sales are in the $350-370k range, then your value should hold up. If there aren't many sales, or have been quite a few distressed sales, might bring your value down to the $260-280k range. Do you still keep in touch with your real estate agent? If so ask them to email you all of the sales in your neighborhood over the past 6 months plus the current listings, so you can get a feel of what your home's value likely is.
