I think that may have been one of the things we were thinking at the time. Honestly, my recollection of the first half to two-thirds of last year is mostly a haze of stress and numbers, so conversations are long gone.
We're thinking about building an addition now instead of selling and moving. Probably have to knock out the back deck to do it, though. It's a ways off, though, and a lot can change in a few years.
I predict at least 10 years in the place, so that's my ideal payoff window. I'm angling for a net-zero house, which I'm willing to bet could fetch a substantially higher price in the market. But I'd also like to reap that benefit while I'm there.
The geothermal thing is a really neat technology, and if I were more handy with things like wiring 30 amp circuits and HVAC, I'd consider getting the stuff and installing it myself. That'd cut the price in half. But that's a big step, and I don't want to fuck it up.
We'll see what the ASHP can bring to the table.
