A whole-exterior project is one of the larger cheques a homeowner writes, and most are funded rather than paid outright. The options are not interchangeable: they differ in what secures them, what happens if you sell, how quickly they close, and how much protection you have if something goes wrong. We are a contractor, not a lender or a financial adviser, and nothing here is a recommendation about your finances. What we can do is describe the instruments accurately, flag the ones where California has written specific consumer protections, and be straight about the one that most often surprises people at resale.
Paying from savings, and why it deserves to be on the list
It gets skipped in articles like this because there is nothing to explain and nobody earns anything from it, but it belongs first. Paying outright costs nothing in interest, closes instantly, keeps your leverage intact, and — importantly for an exterior project — makes it easy to **phase**. Our phased exterior remodel guide covers how to draw phases along the building's seams so that phasing does not quietly cost more than it saves. If the choice is between financing a whole envelope now and paying cash for the failing half now and the rest in two years, the second is often the better decision even though it is the smaller project. The cost of borrowing is a real number; compare it against the cost of an extra mobilisation rather than assuming the package must win.
Home equity: HELOC and home equity loan
Both are secured by your house, which is what makes the rates lower than unsecured borrowing and also what makes the stakes higher. A **home equity loan** is a lump sum at a fixed rate over a fixed term — predictable, and a good fit for a project with a known scope. A **HELOC** is a revolving line you draw against during a draw period, usually at a variable rate, which suits a **phased** project where you do not want to borrow the whole amount up front. The Consumer Financial Protection Bureau publishes plain-language material on both, including the disclosures you are entitled to. The things to compare are the rate structure, whether there are draw or annual fees, closing costs, and what happens at the end of the draw period — a HELOC that converts to a repayment period with a much larger payment is a common surprise rather than a rare one.
Cash-out refinance
Replacing your existing mortgage with a larger one and taking the difference in cash. It made obvious sense when it let people lower their rate at the same time; it makes much less sense when the existing mortgage carries a rate below what is available today, because you are repricing the whole balance to fund a fraction of it. The arithmetic is specific to your loan and worth doing properly rather than by intuition: compare the total interest on the new full balance against the total interest on a second, smaller instrument at a higher rate. For many households with an older, cheaper first mortgage, a home equity product wins comfortably. Closing costs are also materially higher than on a HELOC, and the timeline is longer — which matters if the project is driven by an active leak rather than by a plan.
Unsecured personal loans
Faster to close, no lien on the house, and rates that reflect both of those. A personal loan is worth considering for a **smaller** exterior scope — a single elevation, a repair, a window set — where the amount is modest enough that the rate difference costs less than the closing costs and time of a secured product would. It is also the right instrument when you do not want to encumber the property, for example if a sale is close. Two cautions: check whether there is a prepayment penalty, and be sceptical of very long terms, because a low monthly payment on a long amortisation can quietly cost more in total than a shorter term you could actually afford.
Contractor-arranged financing
Many contractors, including us, can point you at third-party lenders. This is a legitimate convenience and it is also the arrangement that most rewards reading carefully. The questions worth asking are: **who is the actual lender**, what is the **APR** rather than the monthly payment, is there a **promotional period** and what is the rate after it, is any **fee paid to the contractor** in connection with the loan, and does taking the financing change the **price of the work**? A deferred-interest promotion that retroactively charges interest from day one if the balance is not cleared in time is a specific structure to identify and understand before signing. None of this means contractor-arranged financing is bad — it means the loan is a separate transaction from the construction contract and deserves separate scrutiny.
PACE: how it is different, and why it needs its own section
**Property Assessed Clean Energy** financing is repaid through an assessment on your **property tax bill** and attaches to the property rather than to you personally — which is the feature that makes it distinctive and the feature that causes trouble. It has a documented history of consumer harm in California, which is precisely why the legislature intervened: the Department of Financial Protection and Innovation regulates PACE program administrators under the California Financing Law pursuant to **AB 1284 (Chapter 475, Statutes of 2017)** and **SB 242 (Chapter 484, Statutes of 2017)**, with final regulations effective **October 1, 2021**. Those reforms brought in administrator licensing and requirements around evaluating a homeowner's ability to pay. The practical cautions that remain: it sits on your tax bill, so a missed payment is a property tax problem; it can complicate a **sale or refinance**, because some lenders will require it be paid off first; and eligibility for a given measure is programme-specific. If PACE is presented to you, read the DFPI's own homeowner materials before signing, not the marketing.
The contract is a separate document from the loan
Whatever instrument you use, keep the construction contract and the financing separate in your head and on paper. California's B&P §7159 sets what a home improvement contract must contain, and §7159.5(a)(3) caps the down payment at **$1,000 or 10 percent of the contract amount, whichever is less** — that cap does not disappear because a lender is involved. Payments must still follow work performed under §7159.5(a)(5). And your cancellation rights under §7159(e) run on the construction contract independently of the loan's own rescission rules. If a financing arrangement appears to override any of that, stop and ask why. Our contract requirements guide sets out the whole checklist.
What we will and won't do
We will give you an itemised estimate that separates the components, so you can size the borrowing to a scope rather than to a bundled figure, and we will price a phased plan so you can compare financing the whole thing against paying for part of it now. We will tell you plainly when we think the failing half is the right project and the rest can wait. What we will not do is advise you on which instrument suits your finances, project what your house will be worth afterwards, or promise that a project pays for itself — our does new siding increase home value guide is careful about what the resale evidence does and does not support. For the financing decision itself, a lender, a credit union, or a fee-only financial adviser is better placed than any contractor.
Exterior project financing, by what actually differs
| Option | Secured by | Best fit | Watch for |
|---|---|---|---|
| Savings | Nothing | Any scope; makes phasing easy | Opportunity cost of the cash |
| Home equity loan | Your home | A known, fixed scope | Closing costs; a lien on the property |
| HELOC | Your home | A phased project drawn over time | Variable rate; the payment jump at end of draw |
| Cash-out refinance | Your home | When it also improves your rate | Repricing a cheap first mortgage; higher closing costs |
| Personal loan | Nothing | Smaller scopes; no lien wanted | Higher rate; prepayment penalties; long terms |
| Contractor-arranged | Varies by lender | Convenience | APR vs monthly payment; deferred-interest promotions |
| PACE | A property tax assessment | Programme-eligible measures | Sits on the tax bill; can complicate a sale or refinance |
Key takeaways
- Paying from savings belongs on the list — it costs no interest, closes instantly, and makes phasing easy. Compare borrowing cost against an extra mobilisation, not against nothing.
- Home equity loan = fixed lump sum, good for a known scope. HELOC = revolving and usually variable, better for a phased project. Watch what happens when a HELOC's draw period ends.
- Cash-out refinance reprices your whole mortgage to fund a fraction of it — often the wrong instrument if your existing rate is below today's.
- Personal loans suit smaller scopes and situations where you don't want a lien; check prepayment penalties and be wary of very long terms.
- Contractor-arranged financing is a separate transaction from the construction contract. Ask who the lender is, the APR, what happens after a promotional period, and whether it changes the price.
- PACE repays through your property tax bill and attaches to the property. DFPI regulates administrators under AB 1284 and SB 242 (2017), regs effective Oct 1 2021. It can complicate a sale or refinance.
- The §7159.5 deposit cap — $1,000 or 10%, whichever is less — does not disappear because a lender is involved.
FAQ
Quick Answers
Generally, secured borrowing against home equity carries lower rates than unsecured personal loans, because the house secures it — which is also what raises the stakes. But 'cheapest' depends on your existing mortgage rate, closing costs, the size of the project and how long you will carry the balance. A cash-out refinance that reprices a cheap first mortgage to fund a fraction of it can be the most expensive option despite showing the lowest headline rate.
A home equity loan suits a project with a known, fixed scope: a lump sum at a fixed rate over a fixed term. A HELOC suits a phased project, because you draw only what you need when you need it — but the rate is usually variable and the payment can rise sharply when the draw period converts to repayment. Match the instrument to whether you are buying one project or several.
PACE is regulated: California's DFPI oversees program administrators under the California Financing Law pursuant to AB 1284 and SB 242 (both 2017), with final regulations effective October 1, 2021, and those reforms brought licensing and ability-to-pay requirements. The structural cautions remain regardless: it is repaid through your property tax bill, it attaches to the property, and it can complicate a sale or refinance because some lenders require it be paid off first. Read the DFPI's own homeowner materials before signing.
No. B&P §7159.5(a)(3) caps the down payment at $1,000 or 10 percent of the contract amount, whichever is less, and that applies regardless of how the work is funded. Payments must still not exceed the value of work performed or material delivered under §7159.5(a)(5). If a financing arrangement appears to override those rules, that is a reason to stop and ask why.
It depends on the arithmetic, and it is worth actually doing. Compare the interest cost of financing the whole envelope against the extra mobilisation and access cost of phasing it. On a house with cheap access, phasing often wins. On a three-storey or hillside lot where staging is the dominant line, packaging often wins. Get the whole plan priced with access itemised so you can see the comparison rather than guess at it.
Who the actual lender is; the APR rather than the monthly payment; whether there is a promotional period and what the rate becomes afterwards, including whether deferred interest is charged retroactively; whether any fee is paid to the contractor in connection with the loan; and whether taking the financing changes the price of the work. The loan is a separate transaction from the construction contract and deserves separate scrutiny.
