What characteristics are you looking for?

Plenty of investors are using direct mail to find properties that fit your criteria by contacting owners who share characteristics of owners who are likely to be ready to sell.Absentee Homeowners with High Equity are the tried and true target as many people tire of the responsibility of owning property that they don't live in.Seniors with 15+ year ownership is  another good one.

Pictures always help, as do animals.
