Is a HELOC Cheaper Than a Fixed Home Equity Loan for a $40,000 Renovation?

Image
A homeowner planning a $40,000 renovation usually checks one number first: which loan has the lower rate today. Right now that is the home equity line of credit, not the fixed-rate home equity loan. But a HELOC's rate is variable for the full repayment period, while a fixed home equity loan locks in today's rate for the life of the loan. Financed over 10 years, that difference can flip the real cost in either direction. So the honest way to read the comparison is not "which rate is lower" but "what is the one number that separates them actually made of." That number is $3,256.70, and the rest of this post takes it apart. Photo: Celestin bonaventure, Wikimedia Commons , CC BY-SA 4.0 — generic illustrative renovation photo, not tied to the specific loan figures below. Key takeaways As of November 4, 2026, the national average HELOC rate is 7.49%, versus 8.77% for a 10-year fixed home equity loan, per Bankrate's lender survey. On a $40,000, 10-year...

Car Loan or Mortgage First? What a 1.25-Point Rate Gap Actually Costs Over 5 Years

Image
A household has a $350,000 mortgage balance at today's going rate and a $28,000 car loan, and $300 a month they could put toward either one. The instinct for a lot of people is to attack the car loan first — it's the smaller balance, it feels winnable, and being "debt-free" on the car sooner has an obvious appeal. The math says something different, and the gap between the intuitive answer and the correct one is worth walking through with real numbers, because the size of that gap depends entirely on the interest rates involved — and in this specific case, it's smaller than you'd expect.

80/10/10 Piggyback Loan or Monthly PMI? The Real 5-Year Cost on a $400,000 Home With 10% Down

Image
On a $400,000 home with 10% down, splitting the financing into an 80/10/10 piggyback loan comes out about $29,000 ahead of taking one 90%-loan-to-value mortgage and paying monthly private mortgage insurance (PMI) over the first five years, in the worked example below. The gap keeps growing every year PMI stays on the single loan — which, by amortization alone, is more than eight and a half years. A new model home opens for buyers.

Key takeaways On a $400,000 home with 10% down, an 80/10/10 piggyback loan's combined payment is about $2,659/month versus about $2,916/month for one 90% loan with monthly PMI, in this worked example. Over 5 years, the piggyback path costs roughly $29,080 less once both the cash paid and the remaining loan balances are counted together. The PMI route doesn't jus...

Should You Assume a Seller's 3.25% FHA Loan, or Take a New One at 7.18%? The Real 5-Year Cost

Image
Correction November 11, 2026: The rate gap between the assumed 3.25% FHA loan and the 7.18% new-loan rate was given as roughly 394 basis points; 7.18% minus 3.25% is 393 basis points. The paragraph on approval risk also stated FHA’s underwriting thresholds as a flat “580 or higher” score and “43% or lower” debt-to-income; HUD publishes the manual-underwriting limits as a grid (31%/43% with no compensating factors, 37%/47% with one, 40%/50% with two), and that passage has been rewritten to match. Source: HUD FHA Resource Center, maximum qualifying ratios for manually underwritten loans, updated October 8, 2026. A seller's FHA mortgage rarely comes up in a home search, but it should. Assuming an existing FHA loan means taking over the seller's balance, rate, and repayment schedule instead of applying for a new loan. In the worked scenario below, a buyer who assumes a seller's $280,000 FHA loan at 3.25% comes out roughly $49,000 ahead over five years, and about $290 a month a...

15-Year Mortgage or 30-Year Plus Investing the Difference? The Real 10-Year Net-Worth Comparison on a $350,000 Loan

Image

Levittown was built on the FHA/VA-backed long-amortization mortgages that made the 30-year loan standard; illustrative, not a depiction of the homes discussed below. Key takeaways On a $350,000 loan at Freddie Mac's November 5, 2026 average rates (30-year: 7.18%, 15-year: 6.57%), the 15-year payment is $691 a month higher: $3,062 versus $2,371. After 10 years, the 15-year loan has paid off $193,749 of principal versus just $48,397 on the 30-year loan -- a $145,352 equity gap before counting any investment returns. Investing that $691 monthly difference instead would need to earn roughly 10.45% a year, every year, for 10 years just to match the 15-year loan's guaranteed equity position -- above most long-run historical stock market averages. Over a shorter 5-year window, the needed return rises to about 15% a year...

Balance Transfer or Personal Loan to Pay Off $8,000 in Credit Card Debt: Which Costs Less?

Image
To pay off $8,000 in credit card debt, a 0% balance transfer card usually costs less than a personal loan, but only if the monthly payment stays high. At a steady $376.21 a month, a transfer with a 4% fee and a 15-month promotional period costs about $542 in fees and interest, a 24-month personal loan at 11.90% costs about $1,029, and leaving the balance on a card charging 22.36% costs about $2,283. Drop the payment to $200 a month and the same transfer costs about $2,415, more than double the loan. Credit cards in a wallet (file photo). Photo: Chris Potter, Wikimedia Commons , CC BY 2.0 Key takeaways On an $8,000 balance paid at $376.21 a month, the 0% transfer (4% fee, 15 months) costs about $542, the 24-month loan at 11.90% about $1,029, and the original 22.36% card about $2,283. The transfer's advantage disappears once the payment slips to roughly $280 a month; at $200 a month it costs about $2,415 and takes 53 months. A loan origination fee changes the gap: a hypotheti...

What's a Good Homeowners Insurance Deductible? The Real 10-Year Cost of $500 vs. $2,500

Image
Correction November 8, 2026: the one-claim comparison had the $500 deductible subtracted twice. The net 10-year position for the $2,500 deductible with one claim is +$2,620 (not +$3,120), and the gap between the two deductibles in that case is $3,120 (not $3,620). The underlying inputs — $512 a year in premium savings, $5,120 over 10 years, and a $2,000 difference in out-of-pocket cost per claim — are unchanged, as is the two-claim result and the 2.56-claim break-even. Source: arithmetic on the Insurance.com rate data already cited below. Raising a homeowners insurance deductible from $500 to $2,500 saves the average U.S. household $512 a year, according to Insurance.com's state-by-state rate data updated October 28, 2026. Over 10 years that is $5,120 in premium savings — but the real question is whether that savings still wins once you factor in how often a typical homeowner actually files a claim, and the answer depends on a calculation most people never run.

Is a No-Closing-Cost Refinance Really Free? The Real Break-Even on a $350,000 Loan

Image
A no-closing-cost refinance is not free, and it is also not the worst of the options on the table. Those costs — title, appraisal, recording, underwriting — still exist and still get paid; what changes is whether they leave your bank account at closing, get buried in a higher rate, or get added to the loan balance. Those are three different prices for the same thing, and on a $350,000 refinance they do not rank the way the marketing or the usual advice suggests. What follows puts all three side by side at this week's rates, finds the month each one overtakes the others, and then shows how little of that answer depends on the rate level and how much depends on two numbers a lender will quote you in a single phone call.
