If you really have no other place to do your re-search . gp to http://www.realtor.com.
It's not the best gauge for home value's, but at least you know what homes are NOW selling for in that neighborhood .Tax records are okay but they are not a true gauge to get homevalue's for, upgrade's done or bad interiours( repairs or no repairs whatsoever) they are not mentioned or valued by your tax assesor. And perhaps you can just call a friendly ( weichert realrtors) agent to do a CMA on your property ?
good luck I hope I was helpful to you.
