Anecdotes:
One couple of friends moved to the province ~5 years ago and bought a house. Recently he expanded the amount of sod/grass in the yard even though he preferred to xeroscape it, with the reasoning being a future buyer would prefer grass. Possibly true, but they're not planning on moving for at least 5 years.
Another friend couple moved here and bought a SFD about a year ago after a lengthy house hunt. Houses they personally liked were rejected because they were worried that even though they liked it, others might not.
I had to talk my parents out of spending $25k replacing their perfectly serviceable asphalt driveway with concrete, with the sole justification being enhanced curb appeal. Their house is ~70 years old, and has plenty of real-but-invisible problems that could be solved with that money.
It's sheer madness. My homeowning friends and relatives justified their purchases on the grounds of "owning is great, I can do whatever I want on my own land", but constantly talk about every aspect of their houses in terms of either future buyers' preferences or what the neighbours will think. I feel way freer as a renter.
Edit: I pass by
this house occasionally, and I respect its owners a lot. They're clearly making decisions based on what makes them happy, and not for imaginary future owners.
