Payment shock occurs when borrowers who locked in ultra-low rates (e.g. 2% to 3% in 2020-2021) reach their 5-year term renewal and must refinance at significantly higher current market rates (e.g. 4.5% to 5.5%), causing monthly payments to increase by hundreds of dollars.
Yes, you can often refinance back to 25 or 30 years with your lender to reduce monthly payments, although this requires re-qualifying under the mortgage stress test and increases total lifetime interest.
