1. Judging from the contract situation, there is no contract, but there is no original contract. You can take your ID card to the relevant departments of the Housing Authority to get a copy of the contract information.

2. Mortgage information. You can take a bank deposit slip or deposit card and ID card to the banking department to get a copy of mortgage information.

3. I also have a mortgage, and my heart is solid. Because the bank has mortgaged your card in advance, you repay it every month (with principal and interest) and the bank deducts it from this card every month. If there is no money in the card, the bank can't deduct money from the card every month, so the bank will call you in time and deposit the money in the card.

I feel uneasy about how much the bank debits this card every month. You can print a detailed list in the bank with a bank deposit slip, and you will know the details. I feel at ease.
