Might be an unpoplar opinion based on my own conservative approach to personal debt, but I would advise pay cash or defer until you can, unless this is a short term bridge to a near certain liquidity event. You're locking in a big monthly payment and betting the downs of the ups and downs of financial life wont hit at exactly the wrong time.
You're "right", of course, from an economic and fiscal perspective, BUT...
There is something I like to think of as the
theory of reasonableness. Given your current finances, your future prospects, and a bit of a safety net, how do you want to live? Living in a cardboard box and feeding your children out of dumpsters would clearly help your budget and build more wealth, but at some point, you have to live your life. Be reasonable, spend money where you spend the most time, and don't stretch too far. That's about as good as most people can hope for.
In this situation (which I have also found myself in, although it's been a while), the alternative might be to go buy a bigger house with more amenities, and "waste" more money on transaction fees and upgrades. Refreshing your existing home might be a more economical outcome, even if a modest amount of additional temporary debt is taken on to get it.
Just a counterpoint to your well-reasoned and disciplined approach.
