So many comments here glazing over an obvious factor.
You were always going to need somewhere to live, so whatever net worth you have that's locked inside your house is almost theoretical. Even if house prices crash a huge amount, they'll probably come back at some point, unless we're heading for an era of Japan-style stagnation.
It's not ideal, but as someone in a similar boat to you (price agreed mid 2021), I'm probably going to end up technically underwater at some point despite dropping a large deposit. Only thing to do is to bear down and at least be happy that you have a house.
Decreasing home value only matters if you need to sell. If you plan to live in your home for a long time, the changes in the dollar value of the house in the meantime aren't as big of a deal. However, spring was clearly the peak of this market, and it's hard to know how long it will be until a house reaches the same dollar value. It depends a lot on how long interest rates stay high.
I think buying around April is not the worst possible situation. You at least got the good rates, even if you got peak pricing. I've been grinding on sellers so hard that we either backed out or lost our deals. I'm flush with cash so other than not having a home, happy I'm still in the market as I expect sellers to get the message on the state of the market by January. 2023 is the year for anyone that has cash and has been waiting.
My deal won't be perfect either. It may require years of waiting to hit the bottom of the market. I am expecting 2019 pricing soon in my market in 2023, which is all that I'm aiming for.
