You can buy plots of any size in Pune - 1000 sft, 2500 sft, 3270 sft (if there is a seller willing to sell it this way). But usually, people buy in multiples of 500 sft. However, please keep in mind that if you are buying agricultural land, you will not get your name entered in the 7/12 records, unless you buy a minimum of 11 guntas.
