For a 4-member family, choosing between a 2 BHK and 3 BHK flat depends on your lifestyle and budget. If you have young kids or elderly parents, a 3 BHK is generally more comfortable — you’ll have an extra room for guests, study, or future needs. However, if your budget is limited and you prioritize location and amenities, a spacious 2 BHK in a good locality can still be a great option.
