Probate records (Death records) are a valuable source of motivated seller leads for you.
When someone dies, often if they own their house they will leave it to a loved one.
The person who inherits the property may be more interested in cash rather than an old house, especially if the house is out of state and when they find out there are a hold load of taxes and fees involved with inheriting their parents' house.
Most times these houses will have 100% equity/ no mortgage to pay off!
