My mother started doing this, but she pays around 7-8K a year in property taxes. However the interest rate is higher (4-5%)
(she is definitely a low income senior). I don't think she should do it, or if she does, for a very limited time (1, 2 years) just to sell the house. She doesn't listen to any of my financial advice. She also has a heloc she is using as an atm as well.
