Inform your tenant saying the unpaid electrical bills will deduct from the deposit.

Like your situation now, 2 months of unpaid bills.

Deposit is for owner backup right?

If he do the same for rental then you can kick him out already.

Sometimes when you met some bad tenant, don't bother to teach.

They purposely want to drag the payment.

But if the contract both of you signed have the TnC written clearly, then he and you know what is the consequences of not paying the bills/rental.

Haha. You haven't met worst

Ya, that's why.

But Homestay will its own issue too.
