I don’t know of any free websites where you can track mortgage amounts, but if there was one it would show that the owners had refinanced in 2006, with the original balances adding up to $343,000.
Their payments are probably around $2,000 per month, and taxes are low, only $580 per year.
They were trying to sell earlier this year, but gave up in April. Final list (wish) price was $360,000.
