The short answer

In the 25 places most like it the share fell 0.1 points on average, so affordability held up better here. Also notable: Rent run 27% above what its fundamentals predict in the same metro area.

Boulder Hill in 2030: where the trends point

If recent trends hold, the median rent will take about 24% of the median income in 2030, about the same as 24% now.

Citytistics projections to 2030: each figure's own trend, blended with the typical trend across the places we rate, eased toward long-run US growth and carried forward from the latest release. The range is where 80% of places landed when we tested the same method on past releases. On projected 2030 affordability, Boulder Hill does better than 50% of places. Its projected home value growth beats 55%.
