@Vic Iyer It is pretty common in the hot markets around the country for bread and butter lists to get over-used. Absentee Owners might be getting offers every week.
@Dean Iodice - You do need to find Off-Market Leads. Mailing is a good way to do this - both in FL and Memphis.
@Autumn Alexander, When doing a direct mail campaign, consider your audience carefully. There are many levels of motivation - you want to find some that work for your area.
You can work with a list broker to get some suggestions. It shouldn't cost extra money and it's much easier than going online to figure out what you want.
Some might be Seniors with Long-time Ownership and Homeowners with Low Financial Stability Scores. Both have homes that probably are behind in updates and repairs so they won't be expecting top dollar for the house.
Always be sure that whatever list you get that it has been run through the National Change of Address (NCOA). You don't want to waste your postage dollars mailing to old addresses.
