I am the landlord, I have rented a house, and I am the tenant of the property. Now there is a problem, the floor tiles are broken for no reason. Who should repair them?

Since your house is more than ten years old, it must be beyond the warranty period, so it depends on who caused the damage. If it is really caused by the tenant, it must be his responsibility. If the house is naturally damaged over time, you can pay for it yourself. In either case, the property management company has no responsibility, he just introduces the tenant to you, and this is definitely what you asked him to do for you, so the tenant's behavior has nothing to do with the property management company. Thank you.
