Rate Lock Options

Rate locks are one of the few points in a commercial refinance where a single decision can move your borrowing cost by tens of thousands of dollars over the life of the loan. Between application and closing — often 45 to 90 days on a commercial deal — Treasury yields and SOFR can swing meaningfully, and the rate you were quoted at term sheet is rarely the rate you’d get if you simply floated to the closing table. That’s why experienced borrowers compare rate lock options before they pick a lender, not after.

The decision comes down to a trade-off between certainty and cost. Locking early buys protection against rising rates but usually requires a deposit and gives up any benefit if rates fall. Floating keeps your options open but exposes your entire deal economics — debt service coverage, loan proceeds, cash-out — to market movement. This guide walks through the main rate lock structures commercial lenders offer, what each one costs, and how to match the right lock to your deal timeline and risk tolerance.

Quick Comparison Table

Commercial rate locks aren’t a single product — they’re a menu of structures that vary by lender type and by how far in advance you commit. Here’s the side-by-side view:

Lock Option	Typical Rate Impact	Lock Period	Deposit Required	Best For
Standard lock (at commitment)	Baseline — no premium	30–60 days	Often none, or refundable good-faith deposit	Deals with clean, predictable closings
Early rate lock (at application)	+0.05% to +0.15% over baseline	60–90 days	1%–2% of loan amount (typically refundable at closing)	Borrowers who need certainty on proceeds and DSCR from day one
Extended / forward lock	+0.10% to +0.40%, rising with length	3–12+ months	1%–3%, may be partially at risk	Maturing loans locked ahead of a payoff date; construction-to-perm
Float-down lock	+0.125% to +0.25% premium, or a flat fee	30–90 days	Varies; premium often built into rate	Borrowers who want downside protection without giving up a rate rally
Float to close (no lock)	Market rate at closing — could be better or worse	N/A	None	Short timelines, falling-rate environments, high risk tolerance

Two notes on reading this table. First, the deposit on most institutional locks is a breakage protection for the lender, not a fee — if you close as agreed, it’s typically credited back or applied to closing costs. Second, the rate impact figures are indicative spreads over each lender’s baseline pricing; the actual premium depends on the lender, the index, and market volatility at the time you lock. The loan terms themselves — maximum LTV (generally 65%–80% depending on property type), amortization (typically 25–30 years), and prepayment structure — are set by the loan program, not the lock, so compare those separately using a full commercial mortgage refinancing guide.

Deep Dive – Each Option Explained

Standard Lock at Commitment

This is the default structure at most banks and credit unions. You apply, the lender underwrites the deal, issues a commitment letter, and locks your rate for the window between commitment and closing — usually 30 to 60 days.

How it works: The rate is set based on the lender’s pricing index (often the corresponding Treasury yield or SOFR swap plus a spread) on the day of the lock. If your closing slips past the lock expiration, most lenders offer paid extensions, typically 0.125%–0.25% of the loan amount per 15–30 days.

When it wins: Your closing timeline is tight and predictable — third-party reports are ordered, title is clean, and there’s no entitlement or legal complexity. You avoid paying for lock duration you don’t need.

When it loses: You spend 45–60 days in underwriting fully exposed to the market. If the 10-year Treasury moves up 40 basis points between application and commitment, your rate moves with it — and on a loan sized to a debt service coverage constraint, that can shrink your proceeds. Run the scenarios through a DSCR calculator before you decide to float through underwriting: a half-point rate increase on a DSCR-constrained loan can cut maximum proceeds by 5% or more.

Early Rate Lock at Application

Common with agency multifamily lenders (Fannie Mae and Freddie Mac programs) and some life insurance companies, early rate lock lets you fix the rate shortly after application — sometimes within days of a signed term sheet — rather than waiting for full underwriting.

How it works: You post a good-faith deposit, usually 1%–2% of the loan amount, and the lender hedges the rate position. The deposit is refundable at closing but at risk if you walk away or the deal fails to close for reasons within your control. Because the lender carries hedge risk for longer, pricing typically runs a few basis points wide of a commitment-stage lock.

When it wins: You’re refinancing to hit specific proceeds — paying off a maturing loan, funding a partner buyout, or pulling cash out — and can’t afford for rising rates to shrink the loan. It also wins when market volatility is elevated and the value of certainty outweighs a small rate premium.

When it loses: If your property has underwriting risk (occupancy issues, deferred maintenance, environmental questions), locking early puts your deposit at risk on a deal that may not survive diligence. And if rates fall after you lock, you’re committed — the lender hedged your rate, so there’s no free renegotiation.

Extended and Forward Rate Locks

Forward locks fix today’s rate for a closing months in the future — commonly 3 to 12 months out, and up to 24 months on some agency and HUD-insured executions.

How it works: The lender prices the forward hedge into your rate, so the premium grows with the lock length — roughly 3 to 5 basis points per month of forward commitment is a reasonable planning figure, though it varies with the shape of the yield curve. Deposits run 1%–3% and a larger portion may be at risk if you fail to close.

When it wins: You have a loan maturing in nine months with a prepayment penalty that makes closing today uneconomic, but you want to eliminate rate risk between now and the payoff date. Also standard for construction-to-permanent executions where the permanent loan funds after stabilization.

When it loses: Long forwards are expensive insurance. If the curve is pricing in rate cuts, you’re paying a premium to lock a rate the market expects to beat. And a lot can change in twelve months — if your property’s income falls before closing, you may fail the lock’s underwriting conditions and lose deposit money.

Float-Down Options

A float-down is a lock with a one-way door: you’re protected if rates rise, and you can reset lower — usually once — if rates fall by a defined threshold before closing.

How it works: The lender charges for the optionality, either as a rate premium of roughly 0.125%–0.25% or a flat fee. Most float-down provisions require the market to improve by a minimum amount (often 25 basis points) before you can exercise, and the reset typically captures part, not all, of the improvement.

When it wins: Rate direction is genuinely uncertain and the deal can’t tolerate upside risk — you get insurance without fully surrendering a rally. It’s the structure for borrowers who would otherwise agonize over when to lock.

When it loses: In a stable rate environment, you pay for an option you never use. If you’re confident rates will hold or your timeline is short, a standard lock is cheaper.

Floating to Close

No lock at all: your rate is set at (or just before) closing based on the market that day.

When it wins: Rates are trending down, your closing is fast (bridge loans and some SBA and bank deals can close in 30–45 days), or the lender’s lock terms are unattractive. Floating-rate loan products — most bridge and many bank loans — effectively make this decision for you, since the rate resets with the index anyway.

When it loses: Any deal where loan sizing depends on the rate. If you’re at maximum leverage and rates move against you, you may need to bring cash to closing to cover a proceeds cut — the most painful way to learn what a rate lock is for.

Rate Comparison

Lock structures ride on top of the underlying loan pricing, so it helps to see both layers. As of mid-2026, indicative commercial refinance rate ranges by product look like this:

Loan Product	Indicative Rate Range	Typical Lock Availability
Agency multifamily (Fannie/Freddie)	5.50% – 6.75%	Early lock and extended locks widely available
Bank / credit union	6.25% – 7.75%	Standard lock at commitment; extensions negotiable
Life company	5.75% – 6.75%	Early and forward locks common on quality assets
CMBS / conduit	6.50% – 7.75%	Rate typically set near pricing/closing; limited early lock
SBA 504 (effective)	6.00% – 6.75%	Debenture rate set at monthly bond sale
Bridge / debt fund (floating)	SOFR + 2.50% – 5.00%	Floating by design; caps used instead of locks

These are market-indicative ranges, not offers — your actual pricing depends on property type, leverage, DSCR, sponsorship, and market conditions at the time you lock.

What drives the differences between lock options is hedging cost. When a lender locks your rate, it takes a market position on your behalf; the longer and earlier the lock, the more that hedge costs, and the more of that cost shows up in your rate or fees. Volatility matters too: in choppy rate environments, lock premiums and extension fees widen because the lender’s hedge is more expensive. That’s why the same lender may quote a cheap 30-day lock and a noticeably pricier 90-day one in the same week. To see what a few basis points of lock premium actually costs you in monthly debt service, run both rates through a commercial mortgage calculator — on most deals, a 10-basis-point premium is cheap insurance against a 50-basis-point market move.

How to Decide

Four criteria settle most rate lock decisions:

1. How sensitive are your loan proceeds to the rate? Choose an early rate lock if your loan is sized by DSCR at maximum leverage — rate movement directly cuts your proceeds, and certainty is worth a small premium. Choose a standard commitment-stage lock if you’re at conservative leverage with cushion in coverage, because a modest rate move won’t change your deal.

2. How long until closing? Choose a standard 30–60 day lock if your timeline is typical and predictable. Choose an extended or forward lock if you’re closing more than 90 days out — for example, timing a payoff to a prepayment window or a loan maturity. Choose to float if you’re closing inside 30–45 days and can absorb small movement.

3. What’s your view on rates — and can you afford to be wrong? Choose a float-down if you think rates may fall but a rise would damage the deal; you’re paying for asymmetric protection. Choose a plain lock if you have no strong view — certainty is usually worth more than a coin-flip on direction. Choose to float only if you both expect rates to fall and could still close the deal if they rise instead.

4. How solid is your deal in underwriting? Choose a commitment-stage lock if there are open questions on occupancy, condition, environmental, or title — don’t put a 1%–2% deposit at risk on a deal that might not survive diligence. Choose an early lock once those risks are resolved or clearly manageable.

Frequently Asked Questions

How can RefiLoop help with Rate Lock Options?

RefiLoop connects you to 7,000+ lenders. We pre-screen your deal to find the best match — including matching you with lenders whose lock structures fit your timeline, whether that’s an early lock to protect proceeds on an agency refinance or a forward lock timed to a loan maturity. Because lock terms vary widely between lenders, comparing several term sheets side by side is the most reliable way to avoid overpaying for rate protection.

What happens if my commercial loan doesn’t close before the rate lock expires?

Most lenders offer paid extensions, typically 0.125%–0.25% of the loan amount per 15–30 day extension, though terms vary. If you let the lock expire without extending, the loan usually reprices at the current market rate — which may be better or worse than your locked rate. Build buffer into your lock period: if third-party reports and legal work realistically take 60 days, don’t take a 45-day lock to save a few basis points.

Is a rate lock deposit refundable?

Usually, yes — if the loan closes. On agency and life company early locks, the good-faith deposit (typically 1%–2% of the loan amount) is generally refunded or credited at closing. It’s at risk if you walk away from the deal or fail to close for reasons within your control, because the lender used the deposit to cover its hedge position. Read the breakage provisions before you sign; they differ meaningfully between lenders.

Can I negotiate rate lock terms on a commercial mortgage?

Often, yes. Lock length, extension pricing, deposit size, and float-down provisions are all negotiable to some degree, especially on larger loans and with lenders competing for your business. This is one of the strongest arguments for soliciting multiple term sheets: a lender who knows you have alternatives is far more flexible on lock terms than one who believes you have nowhere else to go.

Should I lock my rate if rates are expected to fall?

Market expectations are already priced into forward rates, so “everyone expects cuts” doesn’t mean floating is free money — lenders price forward locks off the same curve. The practical question is whether your deal survives if the consensus is wrong. If a 50-basis-point rise would cut your proceeds below what you need, lock (or use a float-down). If you have room to absorb a move in either direction, floating to a shorter close is a reasonable calculated risk.
