[Q] site to feature distances?

I have a site file w/ 10,000+ sites representing locations where a home has
been sold between 1991-1993. This was extracted from a data set which lists
each homes location, sale price, size of house, size of lot, number of
bedrooms, etc.
I'd like to use grass to figure out how far each home is from the nearest
raster cell which contains a feature which might influence the home's sale
price. Basically, I want to know how far each of my homes are from the
nearest stream or lake, railroad, industrial site, etc.
I need to extract this info for each house and add it to the other variables
in the data set. I'll then use a statistics program to regress sale price on
the set of variables to see how location influences the price for which homes
sell. This will be used to calculate Hicksian consumer surpluses for
willingness to pay to avoid noise pollution, industrial ugliness, etc. based on
house sale price differentials.
Is there an easy way to extract this info in grass? I'm running grass on a
linux system in case that makes a difference.
Thanks for any help!
BTW, I tried posting this to the USENET info.grass.user newsgroup, but it
never showed up. I've been able to do this in the past, but it doesn't seem
to work now. Anyone else having problems or should I moan to my local
sysadmin? This message was e-mailed to grassu-list at moon.cecer.army.mil.
