In any case, this often provides me with a free "out" card even when I waived everything else. 

@Brent Kiger I've been using rentigo for a while now and am really happy - @Cornelius Dudley is right - the tenants pay a service fee for using credit card or ACH and I'm assuming that's where they make their money from. 

Have you heard of drop cards?

Card?

I have no debt (car paid off, no credit card debt, no student loan debt) and pay no mortgage on my current home, so the $3k is unburdened cash. 

Start by getting a credit card and pay it off every month only buy a tank a gas or so so you don't run the bill up.

If you have a business card you could give it to them or put a letter in the mail to the heir. 

And if you play your cards right, your rental could possibly pay both mortgages!..

Just got a new batch the other day from them.I also don't like the yellow letters/post cards either, but it does work.

Always be the winner, and bring your contractor before make an offer on the property, or have an hourly agreement for labor and hand them your credit card for materials.Best,
