Should You Use Contractor Financing? (2026)
Contractor financing (GreenSky, Service Finance, Synchrony) offers convenience and 0% promos but often includes deferred interest traps and hidden dealer fees. Here is how to evaluate it.
Almost every large home improvement quote in 2026 comes with a financing option attached. HVAC, roofing, windows, siding, solar, and the big kitchen and bath remodelers all partner with lenders like GreenSky, Service Finance Company, Synchrony (for HVAC), or Sunlight Financial (solar). The pitch is usually "12 months no interest!" or "$0 down, $199/month." Sometimes it is a good deal. More often, it costs you more than you realize.
Quick Answer: Contractor financing is fine for small projects and genuine 0% promos you can pay off inside the intro window. For anything over $15K-$20K, a HELOC, home equity loan, or personal loan usually costs less. The two biggest traps are deferred interest (you owe retroactive interest if you miss the promo deadline) and dealer fees (the contractor's 4-12% cost for offering you financing, usually baked into the price). Always ask for a cash-price quote and compare total cost.

How contractor financing actually works
When a contractor offers "financing through our preferred lender," here is the usual structure:
The dealer fee is the piece most homeowners never see. If a contractor's cash price is $30,000, they may quote you $33,000 through their financing partner. The extra $3,000 covers the dealer fee and is called a "buydown" for the promotional rate.
The major lenders
These are not predatory by nature, but they are built to make the sale — not to find you the cheapest capital.
The deferred interest trap
This is the single biggest risk in contractor financing.
A typical "12 months 0% APR" promo is usually structured as deferred interest. Here is how it works:
The minimum payments the lender sets are not enough to clear the balance within the promo period. Miss the deadline by a dollar and you pay full interest retroactively.
How to avoid the trap:
Some contractor loans use waived-interest structures instead. Interest does not accrue during the promo, and you just owe the remaining principal afterward. Those are safer but less common, and they usually carry higher rates after the promo.
Dealer fees and the "cash price" test
Dealer fees are the contractor's hidden cost for offering financing. They usually run:
Contractors almost always bake the dealer fee into the price. You will pay it either way, but you may be able to negotiate it out if you pay cash or bring your own financing.
The test:
That is the single most important question to ask before you sign a financing offer.

Red flags in contractor financing
Credit score impact
Contractor financing typically triggers a hard credit inquiry, dropping your score 3-7 points for a while. The new account also affects your average age of credit for the next year or two.
If you are planning to apply for a mortgage or refinance in the next six months, do not open new contractor financing right before. It can change your DTI ratio and your rate tier.
Comparison to HELOC / personal loan
On mid-to-large projects, a HELOC or personal loan is almost always cheaper. A simple example on a $30,000 HVAC project:
OptionRateTermTotal PaidTotal Interest HELOC8.5%10 years~$44,600~$14,600 Personal loan10.5%7 years~$42,700~$12,700 Contractor 7.99% / 84 mo7.99%7 years~$39,300~$9,300 Contractor deferred 0% / 24 mo (missed)17.99% retro + 17.99%7 years~$46,000+~$16,000+
That bottom row — missing the 0% promo deadline — happens all the time and is expensive. The contractor 7.99% scenario can actually win, but only if the dealer fee was not baked into the price. Do the math on total out-of-pocket, not just the rate.

My recommendation
Use contractor financing when it is convenient, the promo is real, and you can realistically pay it off inside the window. For anything else — especially projects over $20K — shop at least three outside lenders first. A HELOC or personal loan is usually cheaper, and the cash-price discount you can get by skipping contractor financing can save 4-10% on the project itself.
Above all: read the promissory note. The protections you need are all in the disclosures. Take the loan agreement home, sleep on it, and talk to a financial advisor or lender before you sign anything over $15K.
Frequently asked questions
Can I refinance contractor financing into a HELOC later?
Yes. If you get a HELOC after the fact, you can pay off the contractor loan and replace it with lower-rate debt. Useful if you got stuck in a deferred-interest trap or a high-rate loan.Does the 3-day right of rescission apply to contractor financing?
If the loan is secured by your home (some are), yes. The federal Truth in Lending Act gives you three business days to cancel. Unsecured contractor loans usually do not have this right. Check the loan agreement.Can I pay off contractor financing early without penalties?
Most contractor loans through GreenSky, SFC, and Synchrony do not have prepayment penalties. Read the promissory note to confirm, especially on longer-term loans.Are 0% APR contractor offers always a trap?
No. Some are genuine "waived interest" offers where you only owe the remaining principal after the promo. Deferred-interest offers are the dangerous ones. The promissory note will tell you which structure you are in.What if I cannot pay off the balance before the promo ends?
Call the lender 60 days before the deadline and ask about conversion options. Some will convert to a fixed installment loan at a reasonable rate. Others will dump you into the retroactive interest charge. Act early.---
