Especially when those 2nd, 3rd, + properties are being used as passive short term rentals. Observing the state of the housing situation “Hmm there aren’t enough homes for normal families to each have a chance, I should turn this extra property of mine into a vacation rental.” does this make said person a POS?
I have a second home but I inherited it. It would need 100s of ks in renos to rent out. It wouldn’t bring me much money to sell it - would probably need to sell for land value only.
But - it’s a place of refuge for my family member in an emotionally abusive relationship, a friend struggling with her marriage, a crash space if anyone I love is in a rough spot. It’s brought my family together and it’s where we gather.
I don’t think this is wrong because I am using it for net positive purposes in the long term, and someone otherwise probably couldn’t use it - it would be a tear-down.
If it’s legally habitable, someone could be living there imo. Just price the rent adequately low for the value. I’m not saying it’s morally evil for you to have it, but it’s definitely a luxury.
