What is a Mortgage Rate Lock?
📚 Rate Lock Explained:
Rate lock = agreement with lender to freeze your mortgage rate for a specific period (usually 30-60 days). During lock period, your rate CANNOT increase, even if market rates spike.
How Rate Lock Works:
Day 1: Lock rate at 6.5% for 45 days
Day 15: Market rates spike to 6.75% → You're protected!
Day 30: Market rates drop to 6.25% → You're stuck at 6.5% (unless float-down option)
Day 45: Close at 6.5% (locked rate)
💡 Key Benefit:
Protection from rate increases: If rates spike 0.25%-0.50% during your home buying process, you're protected! Save $50-$100/month = $18K-$36K over 30 years!

When to Lock Your Mortgage Rate (Perfect Timing)
✅ BEST TIME: Offer Accepted (30-45 Days to Close)
Perfect timing: Lock rate THE SAME DAY your offer is accepted. Why? (1) You know closing date (30-45 days), (2) Lock won't expire, (3) Protected from rate spikes.
Example Timeline:
March 1: Offer accepted, close date April 15 (45 days)
March 1 (same day): Lock rate at 6.5% for 45 days
March 15: Rates spike to 6.75% → You're protected!
April 15: Close at 6.5% → Saved $50/month!
⚠️ OK TIME: Under Contract (15-30 Days to Close)
Acceptable: Lock 15-30 days before closing if you're confident closing will happen on time. Risk: Delays = lock expires = need extension ($500-$1,500).
❌ BAD TIME: Pre-Approval (Before Offer)
Don't lock: During pre-approval or house hunting. Why? (1) No closing date = lock expires, (2) Waste money on extensions, (3) Rates might drop while locked.
Bad Example:
Jan 1: Lock rate at 6.5% for 45 days (no offer yet)
Feb 1: Still house hunting, lock expires
Feb 15: Find house, rates now 6.75% → Lost savings!
Mistake: Locked too early, wasted lock period

Float vs Lock: Which Strategy is Better?
🔒 LOCK Strategy
When: Lock when offer accepted (rates stable or rising)
Pros:
- Protected from rate increases
- Peace of mind (know exact payment)
- Budget certainty
Cons:
- Miss out if rates drop
- Locked at higher rate
- Extension fees if delayed
📈 FLOAT Strategy
When: Float (don't lock) if rates falling or stable
Pros:
- Benefit from rate drops
- Lock at lower rate later
- Flexibility
Cons:
- Risk rates spike
- Lose savings if rates increase
- Stress/uncertainty
💡 Best Strategy (2026):
LOCK when offer accepted if rates are 6.5%+ (high by historical standards). Risk of rates spiking > potential for significant drops. Float-down option: Ask lender for float-down (if rates drop 0.25%+, you can re-lock lower for $500-$1,000 fee).
What If Your Rate Lock Expires?
Option 1: Pay for Extension ($500-$1,500)
Cost: $500-$1,000 for 15-day extension, $1,000-$1,500 for 30-day extension.
When to use: Closing delayed due to appraisal, inspections, or underwriting issues. Worth paying if rates have spiked since you locked.
Option 2: Re-Lock at Current Rate (FREE)
Cost: FREE, but you get current market rate (might be higher or lower).
When to use: Rates have dropped since you locked. Re-lock at lower rate = save money!
Option 3: Cancel Deal (Last Resort)
Cost: Lose earnest money ($1K-$5K) + appraisal/inspection fees ($500-$1,000).
When to use: Rates spiked so much you can't afford payment. Better to lose $2K-$6K than buy unaffordable home.
Rate Lock FAQs (2026)
Q: Can I lock my rate during pre-approval?
A: Technically yes, but DON'T! Lock expires in 30-60 days. If you don't find a house by then, you wasted your lock. Wait until offer accepted.
Q: What if rates drop after I lock?
A: You're stuck at locked rate UNLESS you have float-down option. Ask lender: "Do you offer float-down?" (costs $500-$1,000 but worth it if rates drop 0.25%+).
Q: How long should I lock for?
A: 45 days for standard purchases (FREE). 60 days for new construction or complex deals ($500-$1,000). 30 days for refinances (quick close).
Q: Can I switch lenders after locking?
A: Yes, but you lose your lock. New lender = new rate (current market rate). Only switch if new lender offers MUCH better rate/terms.
