Manufactured Home parks often have a high number of Owners and Site Numbers associated to an address/parcel. This can yield a high number of results when you Search for the address on the SPEAR form (see screen shot entitled Group By Parcel).
The default is to show results grouped by Parcel. In that view, if you check mark the Parcel number, it will check mark all of the Owners. If you check mark just the Owner, it will not pull in the Parcel information. However, if you select the Group By Owner option, you will be able to select the individual Owner, Parcel and Site Number without having to go through and unchecking them all (see screen shot entitled Group By Owner). This is just a little tip to save some time.
