And work on paying your first house off early. The rest comes and can go. Stable home attenuated the unpredictable ups and downs.
What if you have a mortgage with 2.5% interest? Even if I had enough liquid assets to pay it off, I wouldn’t with the current market.
Well that would depend on your interest rate, presumably. Especially since interest is tax deductible in some places.
If you _do_ break up, this also makes it harder for one person to keep the house, which might be bad if there's kids in a local school, etc. If you have 100k in equity it's easier to buy out your ex than if you have 1 million in equity.
