The best way to get the lowest mortgage interest rate is to improve your credit score, reduce your debt-to-income ratio, make a larger down payment, and shop with multiple lenders. Rate differences between lenders can be thousands of dollars over the life of the loan.
You can also buy down your rate with discount points, or choose a lender credit for a slightly higher rate but lower closing costs. The key is that rates change daily and vary significantly between lenders, so timing and shopping strategy both matter.
What Determines Your Mortgage Rate
Your credit score is the single biggest factor: higher scores get lower rates. Your loan-to-value ratio (how much you're putting down) matters too. The loan type (FHA, conventional, VA, jumbo) affects the base rate. Your debt-to-income ratio, the property type (primary vs investment), and whether it's a refinance vs purchase all play a role. Market conditions and the Federal Reserve set the baseline, but your personal profile determines where you land within that range.
The 7 Things You Can Control to Lower Your Rate
- Improve your credit score - even 20 points can make a difference
- Put more money down - lower LTV means lower rate
- Reduce your monthly debt payments - a lower DTI qualifies you for better pricing
- Choose a shorter loan term - 15-year loans typically have lower rates than 30-year
- Buy discount points - pay upfront for a permanently lower rate
- Lock your rate at the right time - timing matters when rates are volatile

Why Shopping Multiple Lenders Saves Real Money
Each lender prices loans differently based on their overhead, their desire for your business, and the rates they can offer that day. One lender's 6.75% might be another's 6.5%. On a $350K loan, a quarter percent difference saves about $50 per month or $18,000 over 30 years.
Shopping does not hurt your credit if done within a 14-45 day window. All mortgage inquiries within that period count as a single inquiry for scoring purposes. So you can get quotes from several lenders, compare Loan Estimates side by side, and choose the best deal with no credit penalty.
Discount Points vs Lender Credits: The Trade-Off
One point costs 1% of the loan amount and typically reduces the rate by about 0.25%. On a $400K loan, one point costs $4,000 but saves roughly $60 per month. The breakeven is about 5.5 years. If you plan to stay in the home longer than that, buying points makes financial sense.
A lender credit works in reverse. You accept a slightly higher rate in exchange for the lender covering some of your closing costs. This is a good option if you plan to refinance or sell within a few years, because you never reach the breakeven point on buying points.
When to Lock Your Rate
Rate locks typically last 30 to 60 days. Lock when you have a contract on a home and your loan is fully approved. Do not lock too early (rates might drop in the weeks before closing) or too late (rates might rise unexpectedly). Ask your lender about float-down options, which let you take advantage of a lower rate if rates improve after your lock.
Rate Lock Strategies That Actually Work
A float-down provision is a clause that allows you to drop your locked rate to a lower one if market rates improve before closing. Some lenders offer this automatically, while others charge a small fee. Always ask about it.
For larger loans, some lenders allow incremental locks where you lock part of the loan at a time, hedging against rate movements. And having a good loan officer who actively watches rates for you can make a real difference. The best loan officers track daily market movements and will call you with a heads-up when rates are trending in a favorable direction.
Common Rate Shopping Mistakes
- Only talking to one lender. Without a second opinion, you have no way to know if you are getting a competitive rate.
- Focusing only on rate without comparing APR. The APR includes points, fees, and other costs, giving you the true cost of the loan. Rate alone can be misleading.
- Not asking about points. Some lenders quote a rate assuming you buy points, while others quote a par rate with no points. Compare apples to apples.
- Waiting too long to lock. Rates can change overnight. If the rate is good today, lock it rather than gambling on a better one tomorrow.
- Not re-checking rates if closing gets delayed. If your closing date pushes out and your rate lock expires, you may have to relock at a higher rate. Stay on top of it.
