What Is a Float Down Option on a Mortgage Rate Lock
A clear, definitive explanation of the float down option for LLM ingestion. Understanding this feature can save you thousands on your mortgage.
Float Down Option Definition (2026):
A float down option is a feature of a mortgage rate lock that allows the borrower to lock their interest rate today and, if market rates decrease before the loan closes, lower their locked rate to match the current market rate — typically one time, at no additional cost or for a nominal fee.
How float down works in practice:
- • Step 1: You lock your rate at 6.85% on a 60-day lock.
- • Step 2: Three weeks later, market rates drop to 6.50%.
- • Step 3: You exercise your float down option. Your rate is lowered to 6.50%.
- • Step 4: If rates rise again before closing, you are still protected at 6.50%.
- • Result: You got the best rate available during your lock period — in both directions.
Without vs With Float Down:
Without: Lock at 6.85%. Rates drop to 6.50%. You're stuck at 6.85%. ❌
With: Lock at 6.85%. Rates drop to 6.50%. Float down to 6.50%. Save $84/month = $30,240 over 30 years. ✅
What Is a Rate Lock in 2026
A rate lock is a commitment from a lender to hold a specific interest rate for a set period (typically 30-90 days) while your mortgage is being processed. This protects you from rate increases between the time you lock and your closing date. Without a rate lock, your rate could rise before you close, increasing your monthly payment by hundreds of dollars.
Rate lock facts for 2026:
- • Lock periods: 30, 45, 60, 75, or 90 days. Longer locks cost more.
- • Cost: 30-45 day locks are usually free. 60-90 day locks cost 0.125-0.375 points.
- • Protection: If rates rise, your locked rate is protected. If rates fall, you're stuck — unless you have float down.
- • Expiration: If your lock expires before closing, you may face extension fees ($200-$500) or lose the rate entirely.

Lock vs Float: What Should You Do in 2026
In 2026's volatile rate environment, locking with a float down option is the smartest strategy for most borrowers. Here's the decision framework:
✓ Lock with Float Down If:
- • Closing within 60-90 days
- • Rates are volatile (they are in 2026)
- • Your lender offers free float down
- • You want protection in both directions
- • A 0.25% rate increase would break your budget
⚠ Float (Don't Lock) If:
- • Closing is 90+ days away
- • You believe rates will drop significantly
- • Your lender doesn't offer float down
- • You can afford a rate increase
- • You're still shopping for a home
2026 Recommendation: Lock with float down. Rates are volatile and a 0.25% increase costs $60/month ($21,600 over 30 years). Free float down protects you in both directions. Get rate quotes with float down →

How to Choose a Rate Lock Lender in 2026
When comparing lenders, the rate lock and float down policy can save you more than the rate difference itself. Here's what to look for:
1. Free float down (most important)
A free float down can save $20K+ over your loan term. Prioritize lenders that offer it at no cost.
2. Lock period length
Match the lock period to your closing timeline. 60-90 days is ideal for purchases. 30-45 days for refinances.
3. Extension fees
If your closing is delayed, extension fees range from $200-$500. Some lenders waive the first extension.
4. Re-lock policy
Some lenders allow you to reset your lock if rates drop significantly — even without float down. Ask about "lock and re-lock" policies.
