Google Search Realtors near Magnolia, Delaware. Click on any of the hundred that show up and contact them. Be careful on shortsale homes, they come with an added fee "Third party fees". I was trying to submit a bid on a home in Smyrna, DE and they wanted 3% Third Party Fees. Foreclosures do not have those kinds of fees associated with them.
