I’m arguing non-homeowner had zero risk and should have zero equity.
The non-homeowner put zero money down for the purchase, they put none of their credit at risk, they took on no liability for the property, and so far there’s no mention of their obligation to pay for upkeep and repairs. Doing those things are the requirements of home ownership while the benefit is the equity. The non-homeowner simply hasn’t done the things to be a home owner. If the did, then they’d be a home owner.
Sorry, I’m not following everyone else’s conversations. I can’t speak to what others are saying. You seem to be comfortable aggregating the conversations and expecting others to do the same, so I can see why you have that response. Clearly we’re at the end of productive conversation. You’re welcome to continue replying if you like, but I won’t be reading your responses.
