Here’s the thing- if you hold off on what seems like a very important long term family project, it could get stalled for other matters, as well. Someone could get hit by a bus or idk, weather events, anything really. Look at your smaller world rather than the bigger world right now. This seems like an outstanding project. Look at the pluses and minuses for the whole project(s.) Is this going to be really beneficial in the long run? I don’t think housing is ever going to be cheap. Wouldn’t it be nice to have that security of having a family homestead you control for the most part? Don’t let the world stand in your way. Lumber is down, plumbing parts are cheap, so is electrical for the most part. You run into a lot of money with tile, countertops, roofing materials, some flooring but the biggest costs come from hiring contractors. If this is diy, you’ve got this! It’s really necessary to hire qualified pros for big electrical and plumbing projects but so many demos and renos can be done (with some online tutorials) yourself.

You have to go with your gut as well as what is best for all of you. Pray on it if you do that. You’re experiencing a stressful time so put it on hold a little while but I would not scrap it. I’ve done a ton of work on my own to my 45 year old house, even lately with prices being higher. They don’t seem unreasonably high compared to food and gas though. Idk where you live but I think it’s a fantastic idea. Hang in there.
