I don't trust appraisals. I have seen incorrect goding. If I don't get a hit from the FFIEC site then I do the following:
1. Go to USPS.com, the U. S. Post Office website, and use the option to check a zip code. When I put in the address it will correct spelling mistakes, streets or cities input as one word that should be two words (example: Greenbriar vs. Green Briar), and other little corrections that can confuse the FFIC site. It will also tell you if the post office doesn't recognize the address at all, which requires further investigation. If it still won't geocode,
2. Use GoogleMaps or some other mappling website to pinpoint the property on a map that will show you the local cross streets and major surrounding roads. Print the map.
3. Go to this site:
http://www.census.gov/geo/maps-data/maps/reference.htmlat the U. S. Census Bureau. Choose census reference maps. Choose your state and county. Use the map you printed out to pinpoint the location.
Once I use one of the census maps, I save it to a folder on my server so I can refer to it again.
