Why don't you use RedGirraffe? It only charges 0.39% + GST.
I also pay rent using my IDFC Club Vistara through RedGiraffe.
Rent - 55k
RedGiraffe Charges - 0.39% + GST (18%) = 253
IDFC Rent Surcharge - 1% + GST (18%) = 652
Total paid - 55905 (extra 905)
Once bill is generated, pay the bill with HDFC Platinum Debit Card from SBI Unipay and get 1% back on the amount (excluding surcharge), in this case - 552. So net net I paid 352 extra for the rent payment. This also fetches CV points as it falls in 1 per 200 category, so I get 276 points and counts towards milestone.
Recently, PayZapp has removed the support of other bank credit cards for rent payments. In that case, can use the IDFC app.
