A homestead exemption in rva won't help if you try to move to nova. It would have to be statewide, but we can see in areas other areas like california and colorado, it doesn't help in any long term way in maintaining affordability. Nor does it help renters, who are often low income, and depending on the extent can cause budget issues from a decline in revenue.

A more economocally effective policy is a low income tax credit.... a "property tax break circuit breaker"
