My question involves landlord-tenant law in the State of: TX
I'm a landlord with a tenant who is behind on her rent, due to her forgetting" to direct deposit one month of rent earlier this year. Our lease has the standard clause stating 10% late fee if rent is 5 days late.
Problem is now he claims she needs more time to come up with the past due rent.
Is there any defacto standard interest rate recommended for landlords to charge tenants that are trying to catch up up their rent? Something like additional 5% each month on the unpaid balance? I know I have the right to serve a detainer warrant but want to know the diplomatic solution without going to court, which will still encourage her to pay up quickly.
