No, that’s not how I read OP’s question. I read it as OP asking whether they should have delayed their own move because their child would
miss having her childhood home. I don’t think they were necessarily expecting the daughter to embrace the new home in Richmond, but I also don’t think they were expecting such an emotional response.
OP—You and your husband made the move that was best for you. Your daughter will be fine. I would not have stayed in DC just so my kid could come home several weeks a year and maybe in the summer. That doesn’t make sense.
OP here. Yes that's certainly one thing going through our minds right now. Would it have been better to wait a year or two. For us the driving factor was the knowledge that we couldn't afford to retire in Washington, nor did we want especially want to. Since at some point we had to leave, we thought we might as well do it sooner rather than later.
However, moving from a house you've lived in for many years and raised a family in is really hard! Much harder than we thought it was going to be. I used to wonder why older couples continued to live in their big houses even as empty nesters. Now I'm a lot more sympathetic.
