How to Refinance Your Mortgage: Step-by-Step Guide

Refinancing your mortgage isn't complicated, but there are seven clear steps. Miss one, and your refinance gets delayed or denied.

I've been a California mortgage broker for 15 years. I've closed thousands of refinances. Here's exactly how the process works and how to avoid the mistakes that slow things down.

The 7 Steps to Refinance Your Mortgage

Step 1: Check Your Current Loan Terms

Before you talk to any lender, know exactly what you have right now.

Pull out your most recent mortgage statement and find:

• Current principal balance
• Interest rate
• Monthly payment (principal + interest)
• Loan type (conventional, FHA, VA, USDA)
• Remaining loan term
• Whether you're paying PMI and how much

Why this matters: You can't calculate savings without knowing your starting point. And lenders will ask these questions on day one.

If you can't find your statement, log into your current lender's website or call them. Every mortgage servicer has a customer service line that can give you this info in 5 minutes.

Broker's Tip: If you have an FHA loan, check whether your mortgage insurance (MIP) is permanent or removable. FHA loans originated after June 3, 2013 have permanent MIP that never goes away—the only way to drop it is refinancing to conventional. That alone might justify your refinance even if rates haven't dropped much.

Step 2: Check Your Credit Score

Your credit score determines your interest rate. A 40-point difference can cost you $100/month.

Get your credit score for free:

• AnnualCreditReport.com (official source, free once per year from each bureau)
• Your credit card company's app (most offer free FICO scores now)
• Credit Karma (gives you VantageScore, which is close but not identical to FICO)

What lenders actually use: FICO score from all three bureaus (Experian, TransUnion, Equifax). They take the middle score.

Current credit score requirements (March 2026):

• 740+: Best rates (currently 6.34% for 30-year fixed)
• 700-739: 0.25% higher (~6.60%)
• 660-699: 0.5% to 0.75% higher (~7.10%)
• 620-659: 1.0% to 1.5% higher (~7.75%)
• Below 620: Conventional won't approve; FHA might if you have strong compensating factors

If your score is under 680, spend 1-2 months improving it before applying. You could save $50-$150/month just by boosting your score 40-60 points.

Quick score boosters:

• Pay down credit card balances below 30% utilization (under 10% is even better)
• Don't close old credit cards (it hurts your average account age)
• Dispute any errors on your credit report
• Ask for a credit limit increase on existing cards (lowers utilization instantly)

Step 3: Shop Multiple Lenders (CRITICAL STEP)

This is the step most people skip. And it's the biggest mistake.

Here's the truth: Rates and fees vary wildly between lenders. One lender might quote 6.5% with $8,000 in fees. Another quotes 6.375% with $5,500 in fees.

Over 30 years, that difference is $15,000+.

Shop at least 3 lenders. Preferably 5.

Where to get quotes:

• Mortgage brokers (like me): We shop multiple wholesale lenders for you. One application, multiple quotes. No cost to you—lenders pay us.
• Direct lenders (Wells Fargo, Chase, Rocket Mortgage): You're dealing with one lender. Their rate is their rate.
• Credit unions: Often have lower rates for members. Worth checking if you belong to one.
• Online lenders (Better.com, SoFi, LoanDepot): Fast, digital process. Rates are competitive but not always the best.

Broker's Tip: All rate shopping within a 45-day window counts as a single credit inquiry. Don't worry about multiple hard pulls tanking your credit—FICO ignores mortgage inquiries made within 45 days of each other when calculating your score.

What to compare:

• Interest rate
• APR (includes fees—gives you apples-to-apples comparison)
• Origination fee / points
• Total closing costs
• Lender credits (if any)

Don't just pick the lowest rate. Look at the total cost to close and the APR. Sometimes a lender offers a super low rate but charges $10,000 in junk fees.

Questions to ask every lender:

1. What's your interest rate and APR for my situation?
2. What are my total closing costs itemized?
3. Are you offering lender credits, or am I paying points?
4. What's the rate lock period? (30, 45, or 60 days)
5. What's your average time to close?

Step 4: Gather Your Documents

Once you choose a lender, you'll need to prove income, assets, and employment.

Standard document checklist:

• ✅ Last 2 years of W-2s
• ✅ Last 2 years of federal tax returns (all pages including schedules)
• ✅ Last 2 months of pay stubs
• ✅ Last 2 months of bank statements (all pages, all accounts)
• ✅ Current mortgage statement
• ✅ Homeowners insurance policy (proof of coverage)
• ✅ Photo ID (driver's license or passport)

If you're self-employed, add:

• ✅ 2 years of business tax returns (1120, 1120S, or 1065 with K-1)
• ✅ Year-to-date profit & loss statement
• ✅ Business license (if applicable)

If you're using rental income to qualify:

• ✅ Lease agreements for all rental properties
• ✅ Last 2 years of tax returns showing Schedule E (rental income/loss)

Broker's Tip: Get PDFs of everything upfront. Don't wait for the lender to ask. The faster you provide documents, the faster you close. Delays in underwriting are 90% caused by borrowers not submitting documents on time.

Streamline refinances (FHA, VA, USDA): These programs skip most documentation. You usually don't need pay stubs, W-2s, or tax returns. See FHA Streamline Refinance Guide and VA IRRRL Guide for details.

Step 5: Apply and Lock Your Rate

Now you submit your formal application and lock in your interest rate.

The application:

• Online form or phone call with your loan officer
• Takes 20-45 minutes
• They'll ask about income, assets, debts, employment, property details

Be honest. Lying on a mortgage application is a federal crime (it's fraud). Don't inflate income, hide debts, or misrepresent your employment.

Rate locks:

• Once you lock, your rate is guaranteed for 30, 45, or 60 days
• If rates drop during your lock, you usually can't get the lower rate (some lenders offer float-down options for a fee)
• If rates rise, you're protected—you keep the locked rate
• If you don't close before your lock expires, you might need to pay an extension fee or re-lock at current rates

When to lock: As soon as you're confident in the lender and ready to proceed. Rates change daily. If you see a rate you like, lock it.

Current rates (March 2026):

• 30-year fixed: ~6.5%
• 15-year fixed: ~5.5%
• FHA 30-year: ~6.35%
• VA 30-year: ~6.25%

Step 6: Appraisal and Underwriting

After you apply, the lender orders an appraisal and sends your file to underwriting.

The appraisal:

• An appraiser visits your home and measures square footage, bedrooms, bathrooms, condition, and compares it to recent sales in your area
• Cost: $500-$700 (you pay upfront or it's rolled into closing costs)
• Takes 7-14 days from order to report delivery
• You need enough equity to qualify: Most refinances require at least 5% equity (95% LTV max). Cash-out refinances require 20% equity.

What if your home appraises low?

If your appraisal comes in below what you expected, you might not have enough equity to refinance. Options:

• Bring cash to closing to make up the difference
• Lower your loan amount (if doing a cash-out refi, take less cash out)
• Challenge the appraisal with comparable sales the appraiser missed
• Cancel the refinance (you're out the appraisal fee but nothing else)

Streamline refinances (FHA, VA) skip the appraisal entirely. That's a huge time and cost saver.

Underwriting:

This is where the lender verifies everything you submitted. The underwriter checks:

• Your income (calls your employer to verify employment)
• Your assets (verifies bank account balances)
• Your credit (pulls your credit report)
• The property value (reviews the appraisal)
• Your debt-to-income ratio (all monthly debts ÷ gross monthly income)

Debt-to-income (DTI) limits:

• Conventional: 50% max DTI (43% is ideal)
• FHA: 50% max DTI
• VA: No hard limit, but most lenders cap at 60%

Example: Your gross monthly income is $8,000. You have:

• New mortgage payment: $2,500
• Car loan: $400
• Student loan: $300
• Credit card minimums: $150

Total monthly debts: $3,350 DTI: $3,350 ÷ $8,000 = 41.9% ✅ (approved)

If underwriting asks for more documents, provide them immediately. The #1 cause of delays is borrowers dragging their feet on conditions.

Common conditions:

• "Provide a letter of explanation for the $5,000 deposit in your checking account on 2/15/26"
• "Provide proof your student loans are in forbearance"
• "Provide proof of homeowners insurance renewal"

Just send what they ask for. Don't argue. Don't delay.

Broker's Tip: Underwriting can take 3-10 days if you respond quickly. It can take 30+ days if you don't. The ball is in your court during this phase.

Step 7: Close on Your New Loan

You made it. Final step: signing documents and funding your loan.

3 days before closing: The lender sends your Closing Disclosure (CD). This is a detailed breakdown of:

• Your new loan amount, rate, and payment
• All closing costs itemized
• How much you're paying out of pocket vs. rolling into the loan

Review it carefully. Compare it to your Loan Estimate from Step 5. The numbers should match within a few hundred dollars. If something looks wrong, call your loan officer immediately.

By law, you have 3 business days to review the CD before closing. This is the TRID rule (TILA-RESPA Integrated Disclosure). The lender cannot legally close your loan until 3 business days after you receive the CD.

Closing day:

• You'll meet with a notary (or go to the title company's office)
• Bring a photo ID
• You'll sign 50-100 pages of loan documents (promissory note, deed of trust, disclosures, etc.)
• If you're paying closing costs out of pocket, wire the funds 1-2 days before closing (no checks over $1,000)

Signing takes 30-60 minutes. The notary will walk you through each document. You don't need to read every word—the important numbers are in the Closing Disclosure you already reviewed.

Funding:

• After you sign, the lender funds the loan (wires the money to the title company)
• The title company pays off your old mortgage
• Your first payment on the new loan is due ~45 days after closing (you'll skip one month of payments during the transition—that's normal)

Your old lender:

• Will receive payoff within 3-5 business days of closing
• Will send you a final statement showing $0 balance
• If you had an escrow account, they'll refund the balance in 2-4 weeks

Broker's Tip: Don't make any big financial moves during this process. Don't open new credit cards, don't buy a car, don't change jobs, don't make large deposits or withdrawals. Any of these can cause your loan to get denied at the last minute.

How Long Does Each Step Take?

Realistic timeline for a standard refinance:

| Step | Timeline | |------|----------| | Shopping lenders | 3-7 days | | Gathering documents | 1-3 days | | Loan application | 1 day | | Appraisal ordered → received | 7-14 days | | Underwriting | 5-10 days | | Final approval → closing | 3-5 days | | Total: | 30-45 days |

Streamline refinances (FHA, VA): 15-25 days because they skip the appraisal and most documentation.

What slows things down:

• Appraisal delays (appraiser backlog in busy markets)
• Slow document submission by borrower
• Title issues (liens, judgments, errors in public records)
• Underwriting conditions not answered promptly
• Self-employment income (takes longer to verify)

How to speed up your refinance:

• Submit all documents upfront before the lender asks
• Respond to underwriting conditions within 24 hours
• Keep your phone on—lenders will call to verify employment
• Don't go on vacation during underwriting

Pro Tips from 15 Years of Closing Loans

1. Don't skip the title search review.

Title companies occasionally mess up. I've seen them miss liens, misread property descriptions, and charge for services not rendered. When you get your Closing Disclosure, review the title section. If something looks off, ask.

2. Don't let lenders rush you at closing.

Some loan officers pressure borrowers to sign before fully understanding the terms. Don't do it. If a number on the CD differs from what you expected, stop the process and get an explanation. You can always reschedule closing.

3. Negotiate your rate.

Yes, you can negotiate. If Lender A quotes 6.5% and Lender B quotes 6.375%, take Lender B's quote back to Lender A and ask them to match it. Many will.

4. Ask about rate lock float-down options.

Some lenders offer a one-time float-down if rates drop significantly during your lock period. It usually costs 0.125% to 0.25% upfront, but it's worth it if rates are volatile.

5. Refinance in the off-season.

Lenders are slammed in spring and summer (home buying season). Refinance in November-February for faster processing and more attention from your loan officer.

6. Don't tell your current lender you're refinancing.

They'll try to retain you with a "loyalty discount" that's almost never better than shopping the market. And some servicers slow-play the payoff process out of spite. Just let them find out when the payoff demand comes through.

7. Keep 2-3 months of mortgage payments in savings.

You'll skip a payment during the transition, but you're still paying interest daily. And if something delays closing, you need to cover your current mortgage. Don't drain your bank account to cover closing costs.

Common Refinance Mistakes to Avoid

Mistake #1: Only checking one lender. You're leaving thousands on the table. Shop at least 3 lenders.

Mistake #2: Focusing only on rate, ignoring fees. A lender quoting 6.375% with $12,000 in fees is worse than a lender quoting 6.5% with $6,000 in fees. Look at APR and total cost.

Mistake #3: Refinancing without calculating break-even. If you're moving in 2 years and your break-even is 4 years, you're wasting money. Do the math first. Use our break-even calculator.

Mistake #4: Opening new credit during the process. New credit cards, car loans, or personal loans tank your credit score and increase your DTI. Wait until after closing.

Mistake #5: Making large deposits without documentation. Underwriters will ask about any deposit over $500 that isn't a paycheck. If you deposit $3,000 in cash from selling stuff on Facebook Marketplace, they'll make you write a letter explaining it. Just don't do it during the refinance process.

Mistake #6: Changing jobs mid-process. Lenders verify employment right before closing. If you switch jobs, they might have to re-underwrite your loan with the new income, which delays closing or kills the deal.

Mistake #7: Not reading the Closing Disclosure. I've seen borrowers sign for loans with rates 0.5% higher than quoted because they didn't read the CD. Read it. Compare it to your Loan Estimate. Ask questions.

What Happens After You Close?

Day 1-3: Your old lender receives payoff. They stop charging interest.

Day 7-10: You receive confirmation your old loan is paid off.

Week 2-3: Your old lender sends an escrow refund check (if you had an escrow account).

~45 days after closing: Your first payment on the new loan is due.

Month 2: You'll receive a welcome packet from your new servicer (the company handling your loan might be different from the company that originated it—this is normal).

Your credit report: Will show the old loan as "paid off" and the new loan as "open." Your score might dip 5-10 points temporarily from the hard inquiry and new account, but it recovers within 2-3 months.
