I am VERY impressed with all those that have their mortgages paid off!!!
We've lived in the same house for ~14 years now - when we bought it (at 24 & 25 yo), we had two mortgages on it (I think one was the PMI mortgage) because we didn't have the 20% down payment. They were a 30 year mortgage. We paid extra on the mortgages (mostly on the PMI one), but not nearly as much as we should have been - DH had a 6 figure salary, and we COULD have saved so much more...
Seven years later, we had a financial setback, and decided to refinance to combine the mortgages, get money out to pay a large expense, and refi to a 20 year mortgage, which we continued to pay a little bit extra on, until DH ended up on LTD and I got laid off. (We still paid, just nothing extra.) That continued for a few years, until we both got back on our feet financially.
More recently, we contested our property taxes, and got it lowered a great deal, but kept paying the same amount (our mortgage payment includes money to go into escrow for taxes), so we're paying down a great bit more.
We're also looking into refinancing again, to take advantage of the lower rates, and we're contesting the property taxes again (some folks around here do it every year!). As it stands, I think we have another 12 years on our mortgage, which would put us at 51 & 52, but we're trying to follow the DR plan, and pay off our mortgage earlier than that.
P.S. Did anyone notice that this thread actually started in 2010?
