Types of Refinancing

Rate-and-Term Refinance

The most common type. You replace your existing mortgage with a new one — at a lower interest rate, a different loan term, or both. No cash is taken out. The goal is to reduce your monthly payment or pay off the loan faster. Ideal when rates have dropped since you bought your home.

Cash-Out Refinance

You refinance for more than you owe and receive the difference in cash. Common uses include home renovations, debt consolidation, or major expenses. You need at least 20% equity remaining after the cash-out. Rates are typically 0.125–0.25% higher than rate-and-term refinances.

Streamline Refinance

Available for FHA, VA, and USDA loans, streamline refinances have simplified paperwork and may not require an appraisal or income verification. They are designed to lower your rate and payment quickly with minimal documentation. You must be current on your existing loan and show a tangible benefit (lower payment).

When to Refinance

Not every rate drop justifies refinancing. The costs of closing a new loan need to be recouped through savings. Here are the situations where refinancing typically pays off:

The 1% Rule (and When to Break It)

The traditional advice says to refinance when you can lower your rate by at least 1 percentage point. However, on larger loan balances, even a 0.5% drop can save hundreds per month. On a $400,000 loan, a 0.5% rate reduction saves about $130/month — over $46,000 over 30 years.

Other Good Reasons to Refinance

The Breakeven Calculation

This is the single most important number in any refinance decision. Divide your total closing costs by your monthly savings to find how many months until you break even.

Example Breakeven Calculation

Closing costs: $8,000. Monthly savings: $200. Breakeven: $8,000 / $200 = 40 months (about 3.3 years). If you plan to stay in the home longer than 40 months, the refinance pays off. If you might move sooner, it doesn't.

Costs of Refinancing

Refinance closing costs typically run 2–5% of the loan amount. For a $300,000 loan, expect $6,000–$15,000 in total costs:

Some lenders offer "no-closing-cost" refinances, but they roll the costs into your rate or loan balance — you still pay, just differently. Compare the total cost over the life of the loan, not just the upfront number.

Documents You Will Need

The Refinance Process Timeline

  1. Week 1: Shop rates from at least 3 lenders. Compare APR, not just the interest rate — APR includes fees.
  2. Week 1–2: Choose a lender, submit your application and documents.
  3. Week 2–4: Lender orders appraisal, verifies employment and assets, processes underwriting.
  4. Week 4–6: Receive closing disclosure (review 3 days before closing), sign documents, fund the new loan.

Total timeline: 30–45 days from application to closing. Streamline refinances can close faster.

Frequently Asked Questions

When does it make sense to refinance your mortgage?
Refinancing typically makes sense when you can lower your interest rate by at least 0.75–1%, reduce your monthly payment significantly, shorten your loan term (e.g., 30-year to 15-year), eliminate PMI after reaching 20% equity, or need cash for major expenses (cash-out refinance). The key is the breakeven calculation — divide your closing costs by your monthly savings to find how many months until you benefit.
How much does it cost to refinance?
Refinance closing costs typically run 2–5% of the loan amount. For a $300,000 loan, expect $6,000–$15,000 in costs including appraisal ($400–$600), title search and insurance ($700–$1,500), origination fee (0.5–1% of the loan), and recording fees. Some lenders offer no-closing-cost refinances, but they typically charge a higher interest rate to compensate.
What is the difference between rate-and-term and cash-out refinancing?
Rate-and-term refinancing replaces your existing mortgage with a new one at a different rate or term — you don't receive cash. Cash-out refinancing replaces your mortgage with a larger loan and gives you the difference in cash. Cash-out refinances typically have slightly higher rates and require more equity (usually 20%+ remaining after the cash-out).
What documents do I need to refinance?
Prepare: two months of pay stubs, two years of W-2s and tax returns, two months of bank statements, your current mortgage statement, homeowner's insurance policy, a government-issued ID, and documentation of any other income (rental, investment, self-employment). Self-employed borrowers need two years of business tax returns and a current profit-and-loss statement.
