Carpet Area Issue

Q: Hi

I am in the process of buying a resale flat in Kandivli Area. It is a 2BHK flat.

Here is the situation:

- Original agreement from Builder to first owner had 3 flats each of 210, 235 and 195 sq ft carpet area

- However, the building was constructed differently for some reason and all 3 flats were combined into 1 with total carpet area of 720 sq ft

- Agreement from Builder to first owner has 3 separate agreements with 210,235 and 195 sq ft

- Agreement from First builder to second builder has 720 sq ft carpet area

- Society NOC provided at the time purchase made by second owner has 720 sq ft carpet area

- Index 2 page has 720 sq ft carpet

My concern is why is there a difference between original agreeement and all other agreements. Also, is it safe to go ahead with the deal? Are there any other documentation that I should be checking to be extra sure on this?

Please advice

Thank you and good luck!
