Requesting Lease Payment from Cosigner

[Nick M.]

Hi Team,

I have a tenant that required a cosigner to move in.  The tenant was new to the country, his brother a long time US resident ultimately signed agreeing to pay in the event of rent default.

Well, with coronavirus the tenant claims he's out of work and can't pay rent.  I've never reached out to a cosigner requesting payment.  Any advice on the language or a letter I can use to reach out to the cosigner?

Thanks!
