If you get the contract, it will be almost the same, because there are loan amount, term interest rate and repayment method when you sign the IOU, and then the money is entrusted to pay the house. Generally, the loan officer forgot to give it, so you can ask him for it directly, or the loan officer doesn't want to write it to the customer if he finds it troublesome, hehe, because the contract is for the Housing Authority, the guarantor and the borrower. ...
However, if the IOU is a blank IOU pre-signed in advance and the money has not yet arrived, you should go to the bank in time to inquire.
