Question for nris who sold property in india: did you apply for form 13 lower tds certificate?

Looking for some practical inputs from anyone who sold property in india recently.

As most of us know, buyers deduct 20% plus surcharge tds under section 195 on the gross sale value instead of actual capital gains.

I know we can claim the refund by filing itr-2, but cpc processing for heavy refund amounts usually takes months.

For those who applied for a lower tds certificate (form 13) through the IT portal prior to the sale:

1. how many weeks did the assessing officer (ao) take to issue the certificate?
2. did the buyer's ca accept the lower tds certificate smoothly during the registry?

Trying to figure out if applying for form 13 in advance is worth the paperwork versus waiting for a refund via itr. thanks!
