Monthly repayment is what you'd pay each month on a capital repayment mortgage, which gradually pays off both the interest and the loan itself.
Interest-only shows what you'd pay if you only covered the interest each month. With this type, you'd still owe the full loan amount at the end.
Loan-to-value (LTV) is the percentage of the property's value you're borrowing. Lower LTVs often mean better interest rates.
Repayment Plan shows how your loan is paid off over time. In the early years, most of your payment goes towards interest. As the balance decreases, more goes towards principal.
