A refinance replaces your current mortgage with a new one. That is all it is. Whether it is a smart move comes down to one question: does the new loan reach a specific goal at a cost you will earn back while you still have it? I would rather tell a homeowner to wait than sell them a refinance that does not pencil out, so this guide gives you the same math I use.
If you want to run your numbers as you read, open the refinance compare tool in another tab.
When does refinancing make sense?
Short answer: when the new loan meets a clear goal and you will keep it past the break-even point, where your savings exceed your closing costs.
Common goals that can justify a refinance:
- Lower payment or rate. Market rates are meaningfully below your current rate.
- Drop mortgage insurance. You have an FHA loan with lifetime mortgage insurance and now have enough equity and credit to move to conventional.
- Shorten the term. Moving from 30 years to 20 or 15 to pay less total interest.
- Get out of an adjustable rate. Locking a fixed rate before an ARM adjusts.
- Access equity. Cash for a renovation, debt consolidation, or another planned need.
- Remove a borrower. After a divorce or when a co-signer wants off the loan.
Goals that usually do not justify it: a small rate change with a short time left in the home, or cash-out for spending that does not improve your finances.
What are the main types of refinance?
Short answer: rate-and-term (change the rate or term), cash-out (borrow against equity), and streamlines for existing government loans (FHA Streamline and VA IRRRL), which need less documentation.
Rate-and-term refinance
You replace your loan to change the rate, the term, or both, without taking meaningful cash out. It is the most common option for lowering a payment, shortening a term, or moving from FHA to conventional to drop mortgage insurance. Conventional mortgage insurance applies above 80% loan-to-value, so the FHA-to-conventional move usually works best once you have about 20% equity and solid credit.
Cash-out refinance
You take a new, larger loan and receive the difference in cash. Conventional and FHA cash-out loans generally cap at 80% of the home's value. VA cash-out can go higher for eligible veterans, subject to lender limits, and it can also be used to move a non-VA loan into a VA loan. A new appraisal and full documentation are normally required.
FHA Streamline
For homeowners who already have an FHA-insured loan. HUD calls it "streamline" because of the reduced documentation and underwriting, not because it is free. The loan must be current, the refinance must give you a net tangible benefit, cash back is limited to $500, and there is often no appraisal. See FHA loans for the program basics.
VA IRRRL
The Interest Rate Reduction Refinance Loan is VA's streamline. It refinances an existing VA-backed loan to lower the rate or move from an adjustable to a fixed rate. You must certify that you live in the home now or used to, so it can work on a former home you now rent out. The funding fee is 0.5% unless you are exempt. The VA loan guide covers exemptions.
| Type | Best used for | Key limits |
|---|---|---|
| Rate-and-term | Lower rate, shorter term, drop FHA mortgage insurance | Full documentation; appraisal unless waived |
| Cash-out | Renovation, debt consolidation, planned needs | Generally 80% of value on conventional and FHA |
| FHA Streamline | Lower rate on an existing FHA loan | Net tangible benefit; $500 cash limit; seasoning |
| VA IRRRL | Lower rate or ARM to fixed on an existing VA loan | 36-month cost recoupment; seasoning; 0.5% funding fee unless exempt |
How do you calculate refinance break-even?
Short answer: divide your total refinance costs by your monthly savings. The result is how many months it takes to earn the cost back.
Example: if the refinance costs $6,000 and lowers your principal and interest payment by $200 a month, break-even is $6,000 divided by $200, or 30 months. If you expect to be in the home and keep the loan for five more years, you come out ahead. If you might move in two years, you probably do not.
Three refinements make the math more honest:
- Compare principal and interest only. Taxes and insurance in escrow do not change because you refinanced, even if the new escrow estimate makes the payment look different.
- Look at total interest, not just the payment. Restarting a 30-year term can lower your payment and still cost more over time. A 20- or 15-year term, or paying your old amount on the new loan, fixes that.
- Price points and credits separately. Paying discount points lowers the rate but raises the cost, which pushes break-even out. A lender credit does the opposite. The rate options calculator shows the break-even on each choice.
VA builds a version of this into law for IRRRLs: the lender has to certify that fees and closing costs are recouped through lower monthly payments within 36 months of the loan date, not counting taxes, escrow, and the funding fee.
What does it cost to refinance?
Short answer: refinance costs include lender fees, appraisal, title and attorney fees, recording, and a new escrow deposit. The total depends on the loan and your state, and you get an itemized Loan Estimate before you commit.
- Lender fees such as origination and underwriting, plus any discount points you choose
- Appraisal, unless the loan qualifies for a waiver or is a streamline without one
- Title search, lender's title insurance, and the closing attorney, since NC, SC, and GA all use attorneys for closings
- Recording fees for the new deed of trust or mortgage
- Program fees, such as the VA funding fee (0.5% on an IRRRL, 2.15% or 3.3% on a cash-out unless exempt) or FHA's upfront mortgage insurance premium
- Prepaids and escrow, which fund your new escrow account. Your old servicer refunds the old escrow balance after payoff.
How you pay matters. On conventional and VA refinances, costs can often be rolled into the new loan within program limits. HUD does not allow closing costs to be added to the new loan amount on an FHA Streamline, so they are paid in cash or covered by a lender credit in exchange for a slightly higher rate. On a VA IRRRL, VA allows the costs to be included in the new loan or covered by the lender through the rate.

What are the rules for an FHA Streamline or VA IRRRL?
Short answer: both require seasoning on your current loan and a real benefit to you. VA adds a 36-month cost recoupment test, and FHA limits cash back to $500.
VA IRRRL rules
- Seasoning: under federal law, the new loan cannot be guaranteed until the later of six consecutive monthly payments on the current loan or 210 days after its first payment due date.
- Rate test: a fixed-to-fixed refinance must lower the rate by at least 0.50 percentage points (50 basis points). Fixed to adjustable requires at least 2.00 points.
- Recoupment: fees and closing costs must be recouped within 36 months through lower monthly payments.
- Occupancy: you certify that you live in the home now or lived there before.
- Existing second mortgage: the holder has to agree to stay behind the new VA loan.
VA also warns about misleading refinance offers, such as promises that you can skip payments. If an offer sounds too good, send it to me and I will tell you what I see.
FHA Streamline rules
- Existing loan: must already be FHA insured and current.
- Seasoning: at least six payments made, at least six months since the first payment due date, and at least 210 days since closing.
- Net tangible benefit: HUD defines it based on the loan being refinanced and the new rate and term.
- Cash: no more than $500 back to you.
- Costs: cannot be added to the new loan amount.
Both programs still involve closing costs. "Streamline" describes the paperwork, not the price.
Cash-out refinance vs. HELOC: which is better?
Short answer: if your current rate is well below today's rates, a HELOC or home equity loan that leaves your first mortgage alone often costs less. If today's rate is similar to or lower than yours, a cash-out refinance can make sense.
| Feature | Cash-out refinance | HELOC or home equity loan |
|---|---|---|
| First mortgage | Replaced with a new, larger loan | Kept as is, with a second lien added |
| Rate type | Usually fixed on the whole balance | HELOCs are usually variable; home equity loans are often fixed |
| Upfront cost | Full closing costs on the entire loan | Often lower, varies by lender |
| Works well when | Today's rate is close to or below yours, or you want one payment | Your first mortgage rate is low and you need a smaller amount or flexible draws |
The math to run: compare the blended cost of your current rate plus the second lien against the new rate on the full cash-out balance, over the years you expect to keep both. A variable HELOC rate can rise, so stress test the payment. I compare both on the same page before you choose.
When should you not refinance?
Short answer: skip it if you will move or refinance again before break-even, if it would trigger repayment of down payment assistance you are not ready for, or if cash-out would fund spending that leaves you worse off.
- You are moving soon. Short stays rarely recover closing costs.
- You have down payment assistance. NCHFA assistance is repaid if you refinance before year 15. SC Housing's Palmetto Home Advantage assistance is repaid if you refinance before its 10-year term ends. Georgia Dream's 0% deferred second mortgage is repaid when you refinance. With the Chenoa Fund, refinancing the FHA loan during the first three years can cancel the forgiveness. See the down payment assistance guide for how each program works.
- Your current rate is already low. If you only need cash, a second lien may cost far less than giving up that rate.
- You would restart 30 years late in your loan without a plan to pay it down faster.
- Your credit or income has dropped. Pricing may be worse than you expect. Sometimes waiting six months helps.
- Your home value has fallen. Lower equity can mean mortgage insurance or a smaller cash-out amount.
What is the refinance process, step by step?
Short answer: define the goal, compare options with break-even, apply, complete the appraisal if required, clear underwriting, and close with an attorney. Timing depends mostly on the appraisal and how quickly documents come in.
- Define the goal. Lower payment, shorter term, drop mortgage insurance, or cash out. The goal decides the loan.
- Compare options. I line up your current loan against one to three new structures with the refinance compare tool, including total cost and break-even.
- Apply and send documents. Your current mortgage statement, homeowners insurance declarations page, and, for full-documentation loans, pay stubs, W-2s or returns, and bank statements.
- Lock your rate when the numbers work for you.
- Appraisal, if required. Some loans qualify for an appraisal waiver, and streamlines often skip it.
- Underwriting and clear to close. I handle conditions and keep you posted.
- Close with your attorney. On a primary residence refinance with a new lender, you generally have three business days to cancel before funds disburse. After payoff, your old servicer refunds any remaining escrow balance.
How can you prepare before you apply?
Short answer: gather your documents early, keep your credit steady, and know your numbers so you can judge offers quickly.
- Pull your latest mortgage statement. It shows your balance, rate, escrow, and whether you have mortgage insurance, which drives most of the comparison.
- Check your credit before you shop. Pay balances down where you can and avoid opening new accounts or financing large purchases until after closing.
- Estimate your home's value honestly. Your equity sets which options are open, so use recent nearby sales, not the highest online estimate.
- Decide how long you plan to stay. That timeline is what you measure break-even against.
- Get more than one Loan Estimate if you want. Comparing them line by line is the cleanest way to see differences in rate, points, and fees. If you already have one from another lender, my free second opinion review walks through it with you.
Local notes: property taxes and insurance are re-estimated at refinance, and coastal insurance increases in places like Charleston, Wilmington, and Savannah can change your new escrow payment.
