> then she likely cannot even afford the taxes on the property anymore and would be forced to leave.

So you're saying she can't afford it. She can't afford to support the city that she now finds herself the beneficiary of? Perhaps because not enough people are paying property taxes? If there was more housing to go around, there would be more people to share that responsibilty.

If she sells she'll be well compensated. She can move somewhere more affordable and have plenty of money left over to give her kids.
