Mortgage rate buydowns are on the rise as homebuyers cope with high interest rates
- Buyers received concessions in 42% of home sales in the fourth quarter, according to RedFin's January report 
- Though buyers can't be sure interest rates will drop by the time they're ready to refinance, mortgage rate buydowns have become a popular strategy to attract buyers who may otherwise be hesitant to purchase a home under today's high interest rates 
- Types of buydowns: - The 1-0 buydown, in which the contract interest rate drops 1% for the first year of the loan. 
- The 2-1 buydown, in which the rate drops 2% for the first year and 1% the second year before returning to the contract rate in the third year. 
- The 3-2-1 buydown, in which the interest rate drops 3% the first year, 2% the second year and 1% the third year before returning to the contract rate in the fourth year.
