What should the landlord do if the tenant conceals his father's illness and age?

If her children can take care of her every day. Basically, for the landlord, whether tenants get along with each other should not be considered, but if it can affect many things, it depends on what you said in the contract signed in advance to withdraw the rent. If there is no problem in the contract. Show some relevant information very clearly. The processing method should be simple! However, we need to communicate more about the specific situation. This is the biggest problem if the tenant defaults on the rent.
