On a site visit, check the plot's boundaries and size against the documents, the access road's width and legal status, drainage and flood signs, overhead power lines, encroachments, neighbours and nearby land use, and for farmland the borewell and water. Take photos and a tape measure, and visit at two different times.
Copies of the patta, layout plan, jamabandi and map; a measuring tape; your phone for photos and location pins.
Weekday and weekend; ideally once after rain.
Pair it with the 12-point document checklist.
Send the plot number, colony and patta photo on WhatsApp. We'll tell you what's verified, what's missing and what to ask the seller.
