Is the mushroom rental company formal? I will rent their house after graduation.

It is really cheating. When renting a house, I deliberately didn't want you to read the contract carefully. I've been rambling. At first glance, it looks like a heartless black-hearted intermediary. Basically, the contract is eight months. If the rent is to be returned within eight months, 20% of the annual rent will be deducted as a penalty. Remember that it is an annual rent, not a monthly rent! Many liabilities for breach of contract in the contract are the tenant's liability punishment, and Party A has no liability clause at all, which is completely overlord clause.
