I was in your situation, but closer to FIRE, 2 years ish. I didn't want a mortgage in retirement. We found the perfect retirement property on which to build and I didn't want to liquidate other investments and incur capital gains so...
I figured out at what rent level I could actually save money when considering property taxes, HOA's, etc and we set out to find a rental under that amount. It wasn't that hard and we put our house on the market. It sold right away.
So we are in the process of finalizing our construction plans. The house equity is sitting in a prime money market account ready to pay for the new house and we have little worries right now, because we're renting.
Some may think we're nuts for moving twice, but it was a great economic decision and we don't mind having less stress in our lives right now.
