I am having a similar issue with a property. We recently had a leak in the kitchen under the sink. Called the plumber the next day and after inspecting the leak soon realized it was a much bigger problem. The old cast iron pipe had split in half and was leaking into the wall behind the kitchen. We opened up the wall replaced the pipes and fixed that leak issue but discovered water damage and mold. Wall and floor are currently open and being inspected. We filed a claim with the insurance company, they are still working on that. In the meantime we offered the tenants a hotel, which at first they refused while the plumbers were there fixing the leak for a week. Now this is week 2 and we need to deal with the mold. We offered a hotel and this time they took it for a week for now until we know if the insurance is going to cover the mold remediation or if we need to do it on our own. I feel horrible, they are good tenants, and I'm trying to get this done ASAP. Here is my question, should I offer a reduction in rent for the inconvenience this has caused?
