Hello Brenda, Assuming you never borrow any more than the costs to establish the loan, the interest that accrues on that little amount in just a few years would be very minimal. When you apply, the lender will give you some key documents to review and one will be an amortization schedule. That schedule will allow you to see what the outstanding balance would be year by year based on the amount you borrowed at closing. Unfortunately, most lender's software will not allow you to factor in multiple draws and changing interest rates though so the initial amortization will only show whatever initial draw you choose and usually at the expected rate which is actually higher than the interest you will be accruing in the beginning. No one can tell you for certain what future rates will do. After 45 years in mortgage banking, the only thing I can tell you for certain is that they will go up, go down, stay relatively the same or some of any or all of these options but I cannot tell you for sure which. I could have retired a wealthy man long ago if I always knew what rates would do in advance but I don't and neither does anyone else. We have a custom calculator available that allows borrowers to insert their own parameters though so you can take the information on your HECM documents and insert them into an excel friendly sheet and see what you would owe if rates rise, decline, if you borrow more money or if you want to pay the balance down at any point. If you are considering a HECM loan but want to see how it would look in the future at various times, I would encourage you to visit our reverse mortgage calculator and then ask your loan officer to send you the loan calculator loaded with your specific information so you can run your own scenarios after that with different rates, draws and payments if you so choose.
