When you’re getting ready to buy a home or refinance, one question comes up almost immediately: should you lock your rate now or wait and hope it improves.
Friends, news headlines, and social media all offer opinions. Some say rates are definitely going down. Others warn they can only go higher. The reality is that even professionals cannot predict short term rate movements with certainty.
What you can do is understand:
- What influences mortgage rates
- How rate locks really work
- How your budget, timeline, and risk tolerance should guide your decision
That combination is more useful than any single prediction.
The Forces Driving Rates Up and Down
Mortgage rates are not set directly by the Federal Reserve, but they’re heavily influenced by the Fed’s actions and the bond market. Specifically, the yield on the 10-Year Treasury Note is the north star for 30-year fixed mortgage rates.
- Inflation is Key: Mortgage lenders hate inflation because it erodes the value of the interest payments they will receive over time. When inflation data comes in “hot” (higher than expected), mortgage rates tend to jump up. When inflation cools, rates often drift down.
- Economic Strength: Paradoxically, good economic news can be bad news for rates. Strong jobs reports often signal to the market that the economy is running hot, which could keep inflation high. This usually pushes mortgage rates up.
- Global Instability: Uncertainty in global markets often drives investors to safe assets like US bonds. This increased demand for bonds lowers yields, which can help lower mortgage rates.
Currently, the market is in a tug-of-war. Inflation is cooling but remains sticky, leading to a volatile rate environment where significant swings can happen week to week.
What It Means to Lock in a Mortgage Rate
A rate lock is a commitment from your lender to honor a specific interest rate and terms for a set period of time.
The Basics:
- Typical lock periods are 30, 45, or 60 days, with longer options sometimes available.
- During the lock period, your rate should not change as long as your application details stay the same and you close on time.
- Some lenders offer a float down option, which may let you capture a lower rate if markets move significantly in your favor before closing.
Locking protects you from rate increases but also limits your ability to benefit from decreases unless your agreement includes a float down or you are willing to reapply or change products.
When Locking Now Often Makes Sense
There are situations where locking your rate sooner rather than later is usually the more practical choice.
Consider locking if:
You’re close to closing
Your loan is approved, you have an accepted offer, and you are within 30 to 45 days of closing. At that stage, small rate changes can directly affect your monthly payment and qualification.
Your budget is tight
A small increase in rate would push your payment beyond your comfort zone or debt-to-income limits.
You value certainty over potential savings
You prefer to know exactly what your payment will be rather than take on the stress of watching daily market moves.
Recent trends have been upward or volatile
If rates have been rising or jumping around, locking can remove a source of uncertainty.
In these cases, the potential downside of waiting often outweighs the possible benefit of catching a slightly lower rate.
When Waiting or Floating May Be Reasonable
There are also scenarios where it can be rational to delay locking, as long as you understand the risk.
Floating may make sense if:
Your closing is not imminent
You’re still house hunting and do not expect to sign a contract for several weeks or months. Prequalifying now and waiting to lock until you are under contract is common.
Your finances are strong and flexible
You can afford some increase in payment without stress, and your debt-to-income ratio has room to absorb a higher rate.
You have a lender with a clear float down policy
You lock to protect against significant spikes, but have a documented opportunity to benefit if rates fall within a certain range before closing.
You’re open to adjusting loan types
You and your advisor may consider adjustable-rate options or shorter terms if fixed rate pricing changes significantly.
Even in these situations, it’s important not to base your entire decision on a single forecast. Use ranges and scenarios instead of all-or-nothing expectations.
How Your Personal Situation Should Drive The Decision
Beyond market considerations, your own profile matters.
Questions to ask yourself:
- How long do I plan to stay in this property?
Shorter stays may make you more flexible about rate changes or loan types.
- How stable is my income?
If your income is variable, a predictable payment from a locked fixed rate can add important stability.
- How sensitive is my overall financial plan to small changes in housing cost?
If you’re near retirement or managing multiple obligations, reducing uncertainty may have more value.
- Do I have room in my budget if taxes, insurance, or HOA fees also increase over time?
Rate is only one piece of the carrying cost.
Discussing these questions with both your lender and your real estate advisor can clarify whether locking is more of a priority or if you can afford to watch and wait.
Practical Strategies to Manage Rate Risk
You cannot control markets, but you can control your approach.
Some practical steps:
- Get preapproved early so you know what you can afford at current rates.
- Work with a lender who explains their lock and float down policies clearly.
- Consider slightly shorter lock periods if your closing date and underwriting status allow, as they can be less expensive.
- If you lock and rates later drop significantly, ask whether a float down, relock, or refinance strategy makes sense over your expected time in the home.
- Keep perspective. A small fraction of a percent makes a difference, but it’s only one part of a long-term financial picture.

FAQs
How do I know if rates are going up or down soon?
No one can know with certainty. You can watch trends in inflation, Federal Reserve statements, and bond yields, and you can read forecasts from credible sources, but all of these are scenarios, not guarantees. The safest approach is to make decisions based on what works for your budget at today’s rate, then treat any future rate improvements as a bonus.
Is it a bad idea to buy when rates are high?
Not necessarily. Higher rates can reduce competition and slow price growth, which may give buyers more negotiating room. If you find a home that fits your needs and you can afford the payment at current rates, it can still be a sound long term decision. You can also explore refinancing later if rates decrease.
How long does a rate lock last and what if we do not close in time?
Common lock periods are 30, 45, or 60 days. If you do not close before the lock expires, you may have to extend the lock, which can involve a fee, or relock at current market rates. It is important to coordinate closing timelines with your lender and agent to avoid avoidable extensions.
What is a float down and should I ask for one?
A float down option allows you to lock a rate now but take advantage of a lower rate later if markets move in your favor, subject to specific rules. These options may cost extra or only be available under certain conditions. If you are concerned about both rising and falling rates, asking lenders about float down policies is worthwhile.
Can I refinance right away if rates drop after I buy?
You can usually refinance once you have some equity and the costs make sense relative to the potential savings. There is no hard rule that you must wait a certain number of years, but lenders will look at factors such as time since purchase, current value, and your credit profile. Your advisor can help you run a break even analysis before moving forward.
Does locking a rate cost money?
Often, a standard 30-day lock is built into the loan pricing (meaning it appears “free”). However, longer locks (like 90 days or more for new construction) typically require an upfront fee or a slightly higher interest rate. Float-down options almost always come with a fee.
Should I pay “points” to lower my rate?
“Points” are prepaid interest. You pay a fee upfront (usually 1% of the loan amount per point) to permanently lower the interest rate on the mortgage. This makes sense if you plan to stay in the home for a long time (5-7 years or more) and do not expect rates to drop significantly in the near future. If you think you will refinance in two years when rates drop, paying points now is likely a waste of money.
Can I unlock my rate if I find a better deal elsewhere?
A rate lock is an agreement with a specific lender. You cannot simply “unlock” it. However, you are not legally forced to close the loan with that lender. You could switch to a different lender who offers a better rate, but you would have to start the application and underwriting process over from scratch, which could delay your closing and put your earnest money at risk.
Deciding To Lock Is About Fit, Not Forecasts
The question “Should I lock my rate now” is less about finding a perfect prediction and more about fitting a decision to your real situation. Mortgage rates respond to complex forces that no one controls. Your job is to:
- Understand how those rates interact with your budget and timeline
- Decide how much uncertainty you are willing to accept
- Choose a path that you can live with even if the market moves in an unexpected direction
If a current rate produces a payment you’re comfortable with and supports your overall financial goals, locking can remove a major variable from the process. If you have flexibility, time, and a lender with sensible options, watching the market a bit longer may be reasonable.
Navigating these financial decisions requires a team you can trust. At Lone Star Realty, we work with trusted lending partners who can guide you through the lock vs. float decision, so you get into your new home with a payment you’re comfortable with.
