Just want to point out that having a cheaper living situation doesn’t preclude homeownership later—it makes it more feasible.

I’ve lived in SF (communally) for about 10 years now. The first 5 years I lived here help me build up my savings, and then a housemate, my wife, and I bought a building in the city that now houses 8 adults. I definitely could not have afforded this paying for a one bedroom in the city, and living with roommates meant I had lots of time to find people who would be willing to go in on a house with me!

But even if this weren’t the case, over 5 years we probably saved ~200k in rent. Putting that into the stock market would typically yield much better returns than owning a home (which is typically a wash after mortgage interest is factored in).
