COVID-19 Mortgage Holiday

Hi all. My tenants have requested the 3 month rent holiday due to their current situation with the coronavirus. I'm interested to know how other landlords are approaching this. I'm tempted to just cover the mortgage costs for 3 months via my own finances instead of requesting a payment holiday with my mortgage company as I've heard that the monthly payable amount AFTER a payment holiday would increase slightly to cover the lost months. Also there seems to be conflicting stories online or whether it can affect your credit rating by requesting a holiday.

Anyone else finding themselves in this situation?
