Once you locate the property, check the legal description. If there are other parcels attached with this property, it will either show it in the legal description (i.e. parcel #1 etc) or it will list lot or plot numbers. Sometimes those property records are even connected to maps to show you exactly where the parcels are located.
Another option is to go down to the city/township or county offices and ask them to help you get information on the parcel. It may take a little time but you will probably get more information and you will know that you have the correct property. Just make sure to bring the listing sheet with you.
Good luck - and I hope it has lake access!
