I don’t think that you should sell. But buying was not the most financially advantageous thing to do.
Sounds like you have an old house (perhaps build in the 1950s) if your neighbor bought for ~10k new. Think about maintenance costs like a new roof, new plumbing, slab leaks, termites, painting, new carpeting, remodeling, etc…
There are many personal reasons for buying. Perhaps people on this board like to focus on the economic fundamentals of buying vs. renting.
PS: I still own so I didn’t follow powayseller’s advice to sell. But I think that it was good advice for anyone who bought after 2000.
