Here's the thing. Having a good marriage/relationship provides many benefits other than a dollar amount. And generally, two people moving forward in the same direction, can make more progress due to splitting expenses, than 2 people solo. Also, having social connection with family and friends, has in a slew of studies been positively correlated with better health, living longer, feeling purpose, etc. It is HEALTH PROTECTIVE. So having a wife say she wants to live with you without a roommate stuck in the middle is a GOOD thing. It means she values your relationship. Wanting a place that she can have people over is a GOOD thing, as it is good to forge those kind of connections/social network, as well as not place all the social burden on each other. It doesn't have to look like a magazine spread (though I wouldn't be surprised if she went through a phase of this before she realizes this. Don't worry, it won't kill you) it doesn't have to be formal, but when you get that reciprocity going, not only is it a lot of fun, it can SAVE YOU MONEY. Yes, because you are not cooking every night, there are some nights other people are cooking. You are buying beverages in bulk, and enjoying them with friends, versus buying a single $6 beer at a bar. And maybe you even meet some friends who make their own beer, or kombucha, or like making bread.
And I'm serious that prices will keep getting higher so honestly, work with your wife on what you budget is to get a house, and go for it.
Trust me, i'm older than you. But if you don't believe me, maybe you and slow traveler with a roommate thrown in can all live in a rv and get to FI at a 90% savings rate, because yanno numbers don't lie.
