Hi Michael, thanks for the question. Looks like Laura beat me to it, I was busy with something else this morning, but she's right - list to sale in Blacksburg has hovered around 4% as a whole. If you dig into the numbers a bit more, you'll find slight differences here and there, but for the most part that's a good rule of thumb.
I went back a year and found out a little more. Among all *residential* properties sold in Blacksburg in the last year, this is how it broke down:
* average list price, $259056 / average sale price, $251437
* median list price, $229000 / median sale price, $225000
Average list to sale percentage was 97%, while the median (I think the median is a better barometer since it gives the mid-point of sales) was 98.2%
Hope that helps, thanks for using Trulia and let us know if there's something else!
