K.P.
Considering what college tuition will cost in the next 10-15 years, I would strongly suggest that you stay put! I know that you would like to move into a nicer house b/c you can now afford to, but having a nice cushy retirement fund (when you can travel the world without worrying) would be far more enticing to me than an upgraded kitchen!
Just as a reference, my parents considered this about 20 years ago and ended up staying in their 1950's ranch with an addition b/c they wanted to pay for our colleges in cash and pay off their home. They are so glad that they did. They don't live in a wonderful neighborhood, but it's a safe neighborhood that is convenient to the beach and our former schools. My father made enough money that they could have moved at any time, but...
- House is paid for
- They out-right own three rental properties
- Cars paid for in cash
- Boat paid for in cash
- Three undergrads paid for and three grad programs paid for
- 2 weddings paid for in cash
- Travel whenever, wherever w/o worry
- Solid investments
- Remodeled kitchen and bath
- Landscaped backyard w/ pool
- At nearly 60, my dad works b/c he loves his job, not because he "has to"
... all because they lived BELOW their means and stayed in their "little house" in their "good, but not great" neighborhood. Think long-term here. There will come a time when you would rather be off visiting your grandchildren than working to pay off a mortgage on a house that's empty!
