How to Get the Best Refinance Rate: 8 Broker Tips

I've helped hundreds of California homeowners refinance over 15 years. Here's what actually works to get the lowest rate.

No fluff. Just the 8 tactics that save my clients the most money.

1. Fix Your Credit Score BEFORE You Apply

Your credit score is the #1 factor in your rate.

A 680 credit score gets you 6.875%. A 740 gets you 6.125%. That's 0.75% difference — $180/month on a $400,000 loan.

How to Boost Your Score Fast (30-60 Days)

Pay down credit card balances below 30% utilization.

Example:

• Credit card limit: $10,000
• Current balance: $6,500 (65% utilization)
• Pay down to $2,900 (29% utilization)
• Credit score jumps 20-40 points

Dispute errors on your credit report.

Pull your credit from all 3 bureaus (Experian, Equifax, TransUnion) at AnnualCreditReport.com. Dispute anything inaccurate.

I had a client gain 35 points by removing a medical bill that was paid but still showing as unpaid.

Don't apply for new credit.

Every hard inquiry drops your score 3-5 points. Skip the new credit card offers.

Don't close old accounts.

Older accounts = longer credit history = higher score. Keep those old cards open (even if you don't use them).

Broker's Tip: Wait until your score hits the next tier before applying. The jump from 679 to 680 can save you 0.375% ($90/month on a $400,000 loan).

2. Build Equity to 20% (Drop PMI, Get Better Rates)

LTV (loan-to-value) matters.

At 80% LTV or less, you get the best rates AND no mortgage insurance.

Above 80% LTV, rates increase by 0.25-0.75% depending on how high you go.

How to Hit 20% Equity

Option 1: Pay down principal.

If you're at 82% LTV, calculate how much you need to hit 80%.

Example:

• Home value: $500,000
• Current loan: $410,000 (82% LTV)
• Target loan: $400,000 (80% LTV)
• Pay down $10,000 before refinancing

You drop PMI AND get a better rate.

Option 2: Wait for home appreciation.

If your home value has increased, you might already be at 20% equity without realizing it.

Example:

• Purchased in 2021 for $450,000, put down 10% ($45,000)
• Loan balance today: $380,000
• Home value today: $525,000
• LTV: 72% (you have 28% equity)

Get an appraisal. You might qualify for better pricing.

Option 3: Use a combo of both.

Pay down $5,000, home appreciated $15,000 → you're at 20%.

Broker's Tip: If you're within $10,000-$15,000 of 20% equity, pay it down before refinancing. The rate savings will pay you back in 12-18 months.

3. Shop 3-5 Lenders (Rates Vary by 0.5-1%)

The biggest mistake I see: applying to one lender and accepting whatever rate they offer.

Rates vary by 0.5-1% between lenders for the same borrower.

Why? Different lenders have different costs, different profit margins, different appetites for risk.

How to Shop Effectively

Get quotes from:

• 1 big bank (Chase, Wells Fargo, BofA)
• 1 credit union
• 1 online lender (Better.com, Rocket, LoanDepot)
• 1 mortgage broker (like me — we shop multiple lenders for you)

Ask each lender for:

• Interest rate
• APR (includes fees)
• Lender fees (origination, points, etc.)
• Estimated closing costs

Compare total cost, not just rate.

A lender offering 6.00% with $8,000 in fees might be more expensive than 6.125% with $3,000 in fees.

Use our refinance calculator to model both scenarios.

Broker's Tip: All rate shopping within 45 days counts as ONE credit inquiry. Don't worry about multiple pulls hurting your score.

4. Lock Your Rate at the Right Time

Rates change daily (sometimes hourly). When you find a good rate, lock it.

How rate locks work:

• You lock your rate for 30, 45, or 60 days
• If rates go up, you're protected
• If rates go down, you're stuck (unless you have a "float down" option)

When to Lock

Lock immediately if:

• Rates are rising
• You found a great rate and don't want to gamble
• You're closing in 30-45 days

Float (don't lock) if:

• Rates are falling
• Economic data suggests rates will drop
• You're willing to take the risk

I tell most clients: lock within 3 days of applying. Bird in the hand beats gambling on rates.

See our rate lock guide for details.

Broker's Tip: Ask about "float down" locks. You lock today, but if rates drop 0.25%+ before closing, you get the lower rate. Costs an extra 0.125%, but worth it if you're nervous about market moves.

5. Time Your Refinance Around Economic Data

Big economic reports move rates. If you're flexible with timing, you can catch dips.

Major reports that move mortgage rates:

• Jobs report (first Friday of every month)
• Inflation (CPI) data (mid-month)
• Federal Reserve meetings (8 times per year)

How to use this:

Example: The Fed is meeting March 19-20, 2026. Markets expect a rate cut. If they cut, mortgage rates might drop 0.125-0.25% the next day.

Strategy: Get pre-approved, gather all your docs, and be ready to lock if rates drop after the Fed meeting.

Caution: This only works if you're ready to move fast. Don't delay your refinance for weeks hoping for a 0.125% drop. You might miss out entirely.

6. Pay Points ONLY If You're Staying 7+ Years

Discount points let you buy down your rate.

1 point = 1% of loan amount = 0.25% rate reduction

On a $400,000 loan:

• Pay $4,000 → rate drops from 6.25% to 6.00%
• Monthly savings: $60
• Break-even: 67 months (5.6 years)

If you're staying 10+ years, paying points saves you tens of thousands in interest.

If you're selling or refinancing in 3-5 years, skip the points. You won't hold the loan long enough to recover the cost.

See our points vs no-points guide.

Broker's Tip: If you're on the fence about staying long-term, don't pay points. It's better to have liquidity (cash in your pocket) than a slightly lower rate.

7. Avoid These Rate-Killing Mistakes

Mistake #1: Applying for New Credit During Your Refinance

Hard inquiries drop your score.

I had a client apply for a car loan 3 days before closing. His credit score dropped 18 points. His rate jumped from 6.125% to 6.375%.

Don't open new credit cards, car loans, or personal loans while refinancing.

Mistake #2: Changing Jobs Mid-Refinance

Lenders verify employment right before closing. If you switch jobs (even to a better job), underwriting might delay or kill your loan.

Wait until after you close to change jobs.

Mistake #3: Making Large Deposits Without Documentation

Underwriters scrutinize any deposit over $500 in your bank account.

If you deposit $10,000 cash, they'll assume it's borrowed money (which hurts your DTI).

Document every large deposit: gift letter, sale of car, tax refund, etc.

Mistake #4: Refinancing Too Soon After Purchase

Some loan types have waiting periods:

• FHA Streamline: 6 months of payments (210 days since closing)
• VA IRRRL: 210 days + 6 payments
• Conventional: No waiting period, but most lenders want 6 months of history

If you try to refinance too early, you'll get denied or pay a higher rate.

8. Use a Mortgage Broker (We Shop for You)

Full disclosure: I'm a mortgage broker. But here's why it matters:

Banks and direct lenders can only offer their own rates.

Mortgage brokers have access to 20-50 lenders. We shop your scenario and find the best rate + lowest fees.

Real example:

• Bank A offers you: 6.50% with $5,000 fees
• I shop your scenario to 12 lenders
• Lender F offers: 6.125% with $3,500 fees
• You save 0.375% in rate + $1,500 in fees

On a $400,000 loan, that's $90/month savings = $32,400 over 30 years.

And brokers don't cost you extra. We get paid by the lender (same as a bank loan officer). Your rate is the same whether you go direct or through a broker — but brokers have more options.

Broker's Tip: Work with a broker who's been licensed 5+ years and has access to at least 15 lenders. Anyone can call themselves a broker. Experience matters.

The Perfect Refinance Timeline

Here's how to stack these tips for maximum savings:

90 days before refinancing:

• Pull your credit, fix errors, pay down cards
• Calculate your LTV (home value ÷ loan balance)
• If you're close to 20% equity, pay down principal or wait for appreciation

60 days before:

• Shop 3-5 lenders (or hire a broker to do it for you)
• Get loan estimates from each
• Compare rates, fees, and total cost

30 days before:

• Choose your lender
• Submit full application
• Lock your rate (unless you're floating strategically)

Closing day:

• Bring cashier's check for closing costs
• Review final numbers (rate, fees, payment)
• Sign, celebrate, save money

Frequently Asked Questions

Q: How much can I really save by shopping lenders?

I've seen 0.5-1% rate differences for the same borrower. On a $400,000 loan, that's $120-240/month ($43,200-$86,400 over 30 years).

Q: Should I refinance if I'm only saving $100/month?

Depends on closing costs. If you're paying $5,000 to close, you need 50 months to break even (4.2 years). If you're staying that long, yes. If not, skip it.

Q: Can I refinance if my credit score dropped since I bought my home?

Yes, but your rate might be higher than your current rate. Run the numbers. Sometimes you still save (if your current rate is 8% and you can get 7.5%, that's still a win).

Q: What's the absolute best refinance rate available right now?

Rates change daily, but as of March 2026:

• Best conventional rate: 5.75-6.00% (780+ credit, 20%+ equity, no points)
• Best FHA rate: 6.00-6.25%
• Best VA rate: 5.625-5.875%

Check current rates here.

Q: Should I wait for rates to drop more?

Maybe. But trying to time the market is risky. If rates are 1%+ lower than your current rate, refinance now. Don't wait for perfection.
