Tenant pays too much in rent.

[Byron Scott]

Hey BP,

What should I do if a tenant pays two months worth of rent by mistake. They haven't caught it but I've been finding out its better to be proactive than reactive in this business. How do I go about giving the money back? Or do I ask if they wanted to be applied to their next month rent? How should I handle this? I'm trying to be really careful about how I handle this being this is my first property and I'm house hacking.
