Hi people! My father has a land near appanaickenpatti which he purchased very long time ago(10yrs back probably). Since it was very long time ago we forgot the exact location of the land and now I'm trying to find it like location. I know it's nearby mainroad and some houses are there but can't find the exact location Do you guys know how can I locate the land?? And what is the local patta office for appanaickenpatti and maybe surveyor details We are also thinking of selling the land, so if you guys know what is the current rates in these area??
