# Refinancing During Rate Lock in New York: What Happens?
If you refinance during a rate lock period in New York, NY, you generally cannot switch lenders or change loan terms without forfeiting the locked rate and paying any associated fees. A rate lock is a contractual agreement with a specific lender that guarantees a set interest rate for a defined period, typically 30 to 60 days. Breaking that lock to refinance with another lender means starting the entire mortgage process over, including a new application, appraisal, and underwriting. In New York, lenders may charge a fee—often 0.5% to 1% of the loan amount—to release the lock, and you lose any upfront costs already paid, such as appraisal or application fees. However, if you refinance with the same lender, they may allow a "float-down" option if rates drop, but this is not guaranteed and often comes with a fee. Always review your rate lock agreement's fine print before making any changes.
A rate lock is a lender's promise to hold a specific interest rate for you while your refinance application is processed. In New York, this is a binding commitment, not a casual handshake. When you lock a rate, you agree to a set interest rate and annual percentage rate (APR) for a fixed number of days—commonly 30, 45, or 60 days. The lock protects you from market fluctuations during the underwriting and closing process.
New York lenders typically offer rate locks at no upfront cost, but the terms vary. The New York State Department of Financial Services (NYDFS) requires lenders to disclose lock terms in writing, including the expiration date and any fees for extending or breaking the lock. Most refinance borrowers do choose to lock their rate rather than float it, and 30- to 45-day lock periods are common — ask your lender what's standard for your loan type. If your lock expires before closing, you may face a rate extension fee—often 0.25% of the loan amount per month—or risk losing the rate entirely.
Technically, yes, but doing so voids the original rate lock. You cannot have two active rate locks on the same property simultaneously. If you apply with a second lender while the first lock is still active, the first lender will cancel the lock, and you forfeit any fees paid toward that application. In New York, this is a common pitfall for borrowers shopping for better terms after locking.
Here's what typically happens:
Switching lenders mid-lock is a gamble: rates can move against you in the days it takes to requalify with someone new, and a meaningful share of borrowers who try this end up worse off simply because the market shifted underneath them. The key takeaway: switching lenders during a lock is risky and expensive. Only do it if you have a clear, documented benefit, such as a significantly lower rate or better terms from the new lender.
Penalties for breaking a rate lock in New York depend on your lender's specific policy and the terms in your lock agreement. Common penalties include:
New York law does not cap these fees, but the NYDFS requires lenders to disclose them upfront in the Loan Estimate (LE) you receive within three business days of applying. If a lender charges a fee not listed in the LE, you may have grounds to dispute it. Undisclosed rate lock fees are a recurring category of consumer complaint to the NYDFS — if you suspect this happened to you, that agency is the right place to file.
Refinancing during a rate lock can increase your closing costs in several ways. First, if you break the lock to switch lenders, you lose any upfront costs already paid, such as the appraisal fee ($500–$700) and application fee ($300–$500). Second, the new lender will charge its own set of fees, including a new appraisal, credit report, and origination fee. Third, if you stay with the same lender but change loan terms (e.g., from a 30-year to a 15-year mortgage), they may require a new rate lock, which could come with a fee.
Here's a worked example for a $400,000 refinance in New York, using typical fee ranges:
| Cost Category | Original Lock (if kept) | Breaking Lock to Switch Lenders |
|---------------|------------------------|----------------------------------|
| Appraisal fee | $600 (paid, non-refundable) | $600 lost + $600 new = $1,200 |
| Application fee | $400 (paid, non-refundable) | $400 lost + $400 new = $800 |
| Rate lock cancellation fee | $0 | $2,000 (0.5% of $400,000) |
| New origination fee | $0 | $4,000 (1% of $400,000) |
| Total additional costs | $0 | $4,000 |
These figures are illustrative — get itemized quotes from your own lender, since fees vary by institution and loan size.
If you refinance with the same lender but change the loan type (e.g., from a fixed-rate to an adjustable-rate mortgage), the lender may treat this as a new application, triggering a new rate lock and associated fees. Always ask your lender: "Will changing loan terms require a new rate lock and additional fees?"
Yes, refinancing during a rate lock will reset your interest rate if you switch lenders or change loan terms with the same lender. The new rate will reflect current market conditions at the time of the new lock, not the original rate. This is a critical risk: if market rates have risen since your original lock, you could end up with a higher rate.
For example, suppose you locked a 6.5% rate on a $400,000 refinance in January 2024. In February, you decide to refinance with a different lender offering a 6.25% rate. However, by the time you apply and lock with the new lender, rates have climbed to 6.75%. You now have a higher rate than your original lock, plus you've lost the fees from the first lender.
Mortgage rates can move noticeably within a single lock window — even a swing of a few tenths of a percentage point over 60 days can add real money to your monthly payment. As a rough example, a 0.25% rate increase on a $400,000 mortgage adds roughly $60–$70 to the monthly payment, so it's worth checking current rate trends before deciding to reset your lock.
If mortgage rates drop after you lock but before closing, you generally cannot automatically get the lower rate. Your rate lock is a fixed agreement. However, some New York lenders offer a "float-down" option, which allows you to adjust your locked rate downward if market rates fall by a certain threshold—typically 0.25% to 0.5%.
Float-down options are not standard, and not every lender offers one. Where they exist, they typically come with a fee—usually 0.25% to 0.5% of the loan amount. In New York, several major lenders offer float-downs on some refinance products, but the terms vary — ask directly whether your lender has this option and what triggers it.
If your lender doesn't offer a float-down, you have two options:
Rate drops during a lock period do happen, but not every borrower who sees rates fall ends up using a float-down successfully — some lenders don't offer it, some borrowers miss the window, and some decide the fee isn't worth it. If rates drop after you lock, ask your lender immediately what your options are and what they'll cost.
New York has several laws and regulations that protect borrowers in rate lock agreements, but they don't guarantee you can break a lock without penalty. Key protections include:
However, New York does not cap rate lock cancellation fees or require lenders to offer float-downs. The state's laws focus on transparency, not price controls. If you believe a lender violated disclosure rules, you can file a complaint with the NYDFS online or call their consumer hotline at (800) 342-3736.
No, you cannot have two active rate locks on the same property. If you apply with a second lender, the first lender will cancel your lock, and you'll lose any fees paid. Always cancel the first lock in writing before starting a new application.
A 45-day rate lock is common in New York, with 30- and 60-day locks also widely available. Longer locks (60+ days) often come with higher rates or fees. Ask your lender what lock periods they offer and how pricing changes with length.
Yes, most lenders offer rate lock extensions, but they charge a fee—typically 0.25% of the loan amount per month. For a $400,000 loan, that's $1,000 per month. Extensions are usually available in 15- or 30-day increments.
Yes, but the impact is usually small. Each mortgage application triggers a hard credit inquiry, which can lower your score by 5–10 points. Multiple inquiries within a 45-day window are often treated as one by credit scoring models, so the damage is limited.
First, review your written lock agreement. If the lender is violating the terms, file a complaint with the NYDFS. You can also contact a real estate attorney. In New York, breach of contract claims can lead to damages, including the difference between your locked rate and the rate you ultimately pay.
New York State does not have a specific program for rate lock costs, but the New York State Homeowner Assistance Fund (HAF) provides assistance for eligible homeowners facing financial hardship, including refinance-related costs, up to program limits. Check with the NYS HAF program at (833) 472-3647 for current eligibility and funding amounts.
Review your rate lock agreement right now. Find the section on cancellation fees and float-down options. If you don't have a written agreement, call your lender and request one. Write down the lock expiration date and any fees for changes. This five-minute check could save you thousands if you need to adjust your refinance plan.
