@Brianna Salas One of the big rules in direct mail is that you DON'T indicate that you have any personal knowledge of the person based on the list you are mailing to.
A good way to get someone defensive is to let them know that you are contacting them because they are in distress.
Instead list some of the challenges of ownership - why they might want to get out (unexpected expenses, taxes, maintenance) and how you can help (quick, cash, as-is, don't have to fix up to have strangers walk through your home)
You should consider working with a list broker to find some off-market seller leads. Seniors with Long-Term Ownership and Low Financial Stability Scores is a good one. You will be reaching people before the bankruptcy cogs start grinding.
I have a blog that talks about the type of message that you might want to send.
