Don't know what you got but if it's anything like my situation and area, do yourself a favor and just do your own if you are just wanting to know and necessarily don't need a certified appraiser...
I've researched the realty market to death and it's so up and down all over the place right now for what I got it's crazy. My appraisal came 14% BELOW tax value (I think he was mad at me) and I had an interested buyer make an offer who had one done on my same place and came out 5% ABOVE tax value. But that's for the 1 bath market which I've discovered to be ridiculous and probably what every crack head in the county owned for there's more foreclosures than actual sales. According to what I'm finding I could add a $20k bath and it would add $50k+ to the value. If I had the time...
Regardless, you will need a licensed appraiser from your area. Lumberton???
If you just want to get a good idea on your own Zillow is a good source. Just find anything in the same neighborhood / or within a few miles that sold recently. And compare the tax values from your local GIS website. It would get you within 5-10% anyways.
Also look and see how many foreclosures in your area for comparables. That would give you an idea if it's a buyers or a seller's market.
