Congratulations to you!
We paid our house off a few years ago. It feels good to have the mortgage be a thing of the past. We had always contributed to 401k and Rothschild, but now we save and invest so much more.
Our total costs for the taxes, insurance, and utilities is about $450 a month, and we could pay that with a part time job if we lost our current jobs as government contractors. And considering what went on in DC last week, that is not outside the realm of possibility.
