Подскажите, как сделать такой запрос в peewee

class House(Model):
    
    name = CharField()
    location = CharField()
    class Meta:
        datadb = db

class Contract(Model):
    
    name = CharField()
    surname = CharField()
    house = ForeignKeyField(House, related_name='contracts')
    class Meta:
        datadb = db

class Payment(Model):
    
    datestamp = DateField()
    Value = FloatField()
    contract = ForeignKeyField(Contract, related_name='payments')
    class Meta:
        datadb = db

house.name, house.location, total_contracts(count), all_payments_sum
