Why the Questions Matter More Than the Rate
Most homeowners start the refinance process by searching for "today's mortgage rates." That's the wrong starting point. A 6.0% rate with $9,000 in closing costs may cost more than a 6.4% rate with $2,500 in closing costs — depending entirely on how long you stay in the home. The questions below force you to think through your specific situation before a lender's sales pitch colors your judgment.
Work through all 10 before requesting a single quote. The whole exercise takes under 30 minutes and will immediately tell you whether refinancing makes sense, what type of refinance to pursue, and which numbers to look for when comparing offers.
Questions 1–5: The Core Math
1 What will my break-even point be?
The break-even point is the number of months until your accumulated monthly savings equal the closing costs you paid. Formula: closing costs ÷ monthly savings = break-even months. If you pay $6,000 in closing costs and save $220/month, you break even in 27 months. If you move in 24 months, you lose money. This single number tells you whether the refinance makes financial sense for your timeline. Use the Break-Even Calculator to find yours before anything else.
2 How long will I stay in this home?
Compare your expected stay with your break-even point. If you're staying 3+ years beyond break-even, a refinance almost certainly makes sense. If you're unsure or planning to move within two years, the math likely doesn't work — unless you can negotiate very low closing costs or qualify for a no-closing-cost refinance. Market timing matters less than personal timeline.
3 What will this refinance cost me?
Closing costs typically run 2–5% of the loan balance. On a $350,000 loan, that's $7,000–$17,500. Know your cost range before getting quotes — it prevents sticker shock and helps you spot unusually low estimates that may be hiding fees. The main categories: origination fee (0.5–1%), appraisal ($400–$700), title insurance ($1,000–$2,500), and government recording fees (varies dramatically by state). Run your numbers through the Refinance Closing Cost Calculator.
4 What is my current credit score?
Your credit score determines both whether you qualify and what rate you'll receive. Conventional refinances require a minimum 620, but 740+ is where the best rates live — lower Loan Level Price Adjustments (LLPAs) apply at higher score tiers, which can reduce your rate by 0.25–0.75%. FHA refinances accept 580+. Check your score 90 days before applying; that gives you time to dispute errors or pay down revolving balances if you're close to a tier boundary.
5 What is my current loan-to-value ratio?
LTV = loan balance ÷ home value. It affects whether you need PMI, what rates you qualify for, and whether cash-out is available. Key thresholds: under 80% = no PMI on conventional; under 75% = access to the best LLPA pricing; under 95% = maximum for most conventional refinances. Check the LTV Calculator with your current balance and a current home value estimate (use a recent appraisal or Zillow/Redfin as a starting point).
Questions 6–10: The Strategic Questions
6 Can I eliminate PMI by refinancing?
If your current LTV is now at or below 80% (because your home appreciated or you've paid down the balance), refinancing to a conventional loan eliminates PMI permanently. PMI typically costs 0.5–1.5% of the loan balance per year — on a $300,000 loan, that's $1,500–$4,500 annually, or $125–$375/month. PMI removal alone can justify a refinance even at a similar interest rate. Run the PMI Removal Calculator to see your current status.
7 Should I shorten or extend my loan term?
Refinancing resets your loan term. If you have 22 years remaining and refinance to a new 30-year, your payment drops but you add 8 years of interest — total lifetime cost often increases even at a lower rate. Shortening to a 15-year loan raises your monthly payment but typically cuts total interest paid by $80,000–$150,000 on a mid-size loan, and 15-year rates are usually 0.5–0.75% lower than 30-year rates. The right choice depends on your cash flow and how many years you've already paid.
8 Am I eligible for a streamline refinance?
If you have a government-backed loan, you may qualify for a faster, cheaper path:
- FHA Streamline: No appraisal, no income re-verification, reduced documentation. Must have existing FHA loan and be current on payments.
- VA IRRRL: No appraisal, no income verification. Veterans only. Must have existing VA loan. Reduces funding fee to 0.5%.
- USDA Streamline-Assist: No appraisal, no credit check. Must have existing USDA loan and a 12-month on-time payment history.
Streamline refinances are faster (2–4 weeks vs. 30–45 days) and often $1,500–$3,000 cheaper than a full refinance.
9 What are my state-specific refinance costs?
State fees can shift your break-even point dramatically. New York's mortgage recording tax adds 1.8–1.925% to your loan amount. Florida charges 0.55% in combined doc stamps and intangible tax. Georgia and Virginia require attorney closings ($500–$1,500) and impose intangible recording taxes. Maryland and Pennsylvania charge recordation taxes on the full new loan amount. Check the state refinance guide for your state's government fee burden before calculating your expected closing costs.
10 Have I compared at least 3 lenders?
Freddie Mac research shows that getting just one additional mortgage quote saves borrowers an average of $1,500 over the loan life. Getting five quotes saves $3,000+. Yet 47% of borrowers get only one quote. Compare a mix: a national bank, a credit union (often lowest rates), and an online lender or broker. All mortgage inquiries within a 45-day window count as a single hard pull for FICO scoring purposes, so there's no credit cost to shopping aggressively.
Putting It Together: Three Real Scenarios
The 10 questions above are inputs to a decision. Here's how the same answers lead to very different choices depending on your situation.
Scenario A: "I might move in 2–3 years"
You have 24 years remaining on a $320,000 loan at 7.25%. Rates have dropped to 6.25%. Monthly P&I savings: approximately $195/month. Estimated closing costs: $7,200. Break-even: 37 months. Since you're likely to move in 24–36 months, you will not recoup the closing costs. In this scenario, the refinance probably doesn't make financial sense — unless you can get closing costs below $4,700 (24 months × $195/month). Negotiate hard on Section A, or consider a no-closing-cost refinance that takes a slightly higher rate in exchange for a lender credit.
Scenario B: "I'm staying in this house for 10+ years"
You have 26 years remaining on a $400,000 loan at 7.0%. Rates drop to 6.0%. Monthly savings: approximately $266/month. Closing costs: $9,000. Break-even: 33.8 months. You plan to stay 10+ years, so you'll break even in under 3 years and then save $266/month for the next 7+ years — total net savings over 10 years: approximately $22,000 after closing costs. For a long-term stay, higher closing costs are acceptable. In this case, paying discount points to secure 5.875% instead of 6.0% might make sense — the incremental savings over 10 years would likely outweigh the point cost. Run the Points Calculator to verify.
Scenario C: "I have an FHA loan and want to get rid of MIP"
You took out an FHA loan in 2021 with a 3.5% down payment. Your home has since appreciated. Your current LTV is now 78%, and your balance is $285,000. Your FHA loan has an annual MIP of 0.55% ($1,568/year, or $131/month) that will never go away — because post-2013 FHA loans with less than 10% down carry lifetime MIP. Refinancing to a conventional loan at 6.25% (no PMI required at 78% LTV) saves $131/month in MIP elimination plus a rate reduction if you're still at your 2021 rate above 6.75%+. The refinance has two components of savings: rate savings plus MIP removal. Your break-even calculation should use the combined monthly improvement (rate savings + $131 MIP savings). In many cases this dramatically shortens the break-even point and makes refinancing highly attractive even at a similar rate.
The Rate Drop Threshold: How Much Do You Actually Need?
The widely cited "1% rule" — only refinance if you can lower your rate by at least 1% — is outdated and oversimplified. The actual threshold depends on your loan balance and closing costs, not a universal percentage.
Here's a realistic look at what different rate drops save monthly on common loan balances, and the break-even in months at $6,000 in closing costs:
| Loan Balance | Rate Drop | Monthly Savings (approx.) | Break-Even at $6,000 closing costs |
|---|---|---|---|
| $200,000 | 0.50% | ~$64/mo | 94 months (7.8 years) |
| $200,000 | 1.00% | ~$127/mo | 47 months (3.9 years) |
| $300,000 | 0.50% | ~$96/mo | 62 months (5.2 years) |
| $300,000 | 0.75% | ~$144/mo | 42 months (3.5 years) |
| $300,000 | 1.00% | ~$191/mo | 31 months (2.6 years) |
| $450,000 | 0.50% | ~$144/mo | 42 months (3.5 years) |
| $450,000 | 0.75% | ~$216/mo | 28 months (2.3 years) |
The 1% rule exists because on a typical 1990s-era $150,000 loan with $3,000 in closing costs, a 1% drop produced a break-even of roughly 25 months — a reasonable threshold. On today's larger loans, a 0.5% drop can make perfect sense. On a small loan or with high closing costs, even 1% might not be enough.
The right question isn't "what's my rate drop?" — it's "what's my break-even point, and will I be here long enough?"
When to Refinance Without Rate Savings
Rate isn't the only reason to refinance. Consider a refinance even with a minimal rate drop if:
- You can eliminate PMI. If your LTV has crossed below 80%, removing PMI saves $60–$200/month on most loans. This counts as monthly savings in the break-even calculation.
- You can convert FHA MIP to no-PMI conventional. As shown in Scenario C above, eliminating lifetime FHA MIP is a major driver of savings even without a significant rate change.
- You want to shorten the loan term. Refinancing from a 30-year to a 15-year typically carries a 0.5–0.75% lower rate AND dramatically reduces total interest — though your monthly payment increases. This is a strategic choice, not a break-even question.
- You want to cash out home equity. If you need funds for renovations, debt consolidation, or investment at a rate lower than personal loan alternatives, a cash-out refinance may make financial sense even without meaningful rate improvement.
Timing Your Application: Rate Lock and Credit Score Prep
Even if your 10 answers point to "yes, refinance," the timing and execution matter for getting the best outcome.
Check and Optimize Your Credit Score First
Check your credit report from all three bureaus (Equifax, Experian, TransUnion) at AnnualCreditReport.com 60–90 days before applying. Look for:
- Errors in account history (wrong balances, incorrect late payments)
- Duplicate accounts that inflate your apparent debt load
- Credit utilization above 30% on revolving accounts (paying these down can boost your score 10–30 points in 30–60 days)
- Authorized user accounts that aren't helping your score
A 20-point score improvement can move you from the 720 LLPA tier to the 740+ tier on a conventional loan, which may reduce your rate by 0.125–0.25%. On a $350,000 loan, that's $26–$54/month — $3,000–$6,500 over 10 years.
Rate Lock Timing
Mortgage rates fluctuate daily. When you find an offer that works for your numbers, locking in the rate is smart — but the lock period matters. Ask each lender:
- What is your average time to close (days from application to funding)?
- What lock period are you quoting — 30, 45, or 60 days?
- What is the extension fee if closing runs past the lock period?
- Do you offer a float-down option if rates drop after I lock?
A 45-day lock costs more than a 30-day lock (usually 0.125% added to rate), but a 30-day lock on a lender with a 35-day average close puts you in a high-risk position. Match the lock period to the lender's realistic closing timeline, not their optimistic one.
What Happens at Closing
Once you've answered all 10 questions and selected a lender, the process follows a predictable path: application → appraisal (if required) → underwriting → clear to close → closing → 3-business-day rescission period. The step-by-step refinance process guide walks through each stage so there are no surprises. The refinance timeline guide explains what causes delays and how to avoid them.

Frequently Asked Questions
What is the most important question to ask before refinancing?
The most important question is: what is my break-even point, and will I stay long enough to reach it? If your closing costs are $5,000 and you save $180/month, you break even in 28 months. If you plan to sell or move in two years, the refinance costs more than it saves regardless of the rate.
How much does a refinance typically cost?
Refinance closing costs typically run 2–5% of the loan balance. On a $300,000 loan, expect $6,000–$15,000 depending on your state, lender, and loan type. Use the Closing Cost Calculator to estimate your specific situation, including lender fees, title insurance, and government charges.
What credit score do I need to refinance?
Conventional refinances typically require a minimum 620 score, though 740+ unlocks the best rates. FHA refinances accept scores as low as 580. VA and USDA streamline refinances may have no minimum score requirement. Check your score before applying so you have time to improve it if you're near a tier boundary.
Do multiple mortgage credit inquiries hurt my score?
No — FICO and VantageScore treat all mortgage inquiries made within a 45-day window as a single inquiry. You can get quotes from 5 lenders in one month with only one hard pull counted against your score. Always shop multiple lenders before deciding.
