Arizona has more renovation loan products than most homeowners realize, and the differences between them are not cosmetic. Choosing the wrong product on a $400,000 renovation can cost $80,000-$150,000 in unnecessary interest, require you to surrender a below-market mortgage rate, or limit your loan amount to less than your project actually costs. This guide compares all five products that are meaningfully available in Arizona in 2026 — what each one is, who it fits, and when it becomes the wrong tool.
One product receives almost no attention in the Arizona market despite being the right fit for the majority of high-equity homeowners doing major renovations: the ARV-based construction loan. It is underwritten on the value of your home after the renovation rather than before, which means the borrowing capacity is set by what you're building toward rather than where you started. We'll spend the most time on it.
The renovation loan spectrum
Five products cover the meaningful range. They differ on two axes: whether the loan amount is limited by current home value or post-renovation value, and whether the first mortgage is left intact or replaced.
| Product | Loan sized on | First mortgage | Typical rate (AZ, May 2026) | Best for |
|---|---|---|---|---|
| HELOC | Current value (up to 85% CLTV) | Left intact | 7.24%–7.99% variable [1] | Projects under $200K with substantial existing equity |
| Cash-out refinance | Current value | Replaced | 6.4%–6.6% fixed [2] | Only if your current rate is already above 5.5% |
| FHA 203(k) | Post-renovation (conforming limits) | Replaced or new | 6.5%–7.1% fixed [3] | Lower-equity homeowners; projects under $650K |
| Fannie Mae HomeStyle | Post-renovation (conforming limits) | Replaced or new | 6.4%–6.8% fixed [4] | Higher credit profiles; slightly fewer restrictions than 203k |
| ARV construction loan | Post-renovation (portfolio, no conforming cap) | Left intact | 7.25%–7.75% fixed during construction [5] | Projects $200K–$2M; preserves low first-mortgage rate |
CLTV = Combined Loan-to-Value. Rates as of May 2026; all variable rates indexed to prime. FHA and HomeStyle limits are set by county; Maricopa County conforming limit for 2026 is $766,550 for a 1-unit primary residence [6].
HELOC: the default for smaller projects
The Home Equity Line of Credit is the renovation loan most Arizona homeowners reach for first, and for projects under $200,000 with strong existing equity, it is often the right call. Arizona credit unions — Arizona Federal, Desert Financial, OneAZ, TruWest — offer HELOCs up to 85% combined loan-to-value with revolving draw periods of 10 years followed by a 20-year repayment period [1].
What a HELOC actually makes available: if your home is worth $1.2M and your mortgage balance is $350K, your equity is $850K. At 85% CLTV, the maximum combined debt is $1.02M, leaving $670K of theoretical HELOC availability. In practice, most credit unions cap the single-draw maximum at $500K-$750K and underwrite income and DTI separately, so the actual approved line is typically lower.
The critical tradeoff: the rate is variable, indexed to prime. The average Arizona credit union HELOC rate in May 2026 is prime + 0.35%, which puts the introductory rate at approximately 7.6% [1]. If the Fed holds rates, that's the cost. If rates rise, the payment steps up automatically. For a 10-year draw period on a $250K line, a 1-percentage-point rate increase adds $208/month to the interest-only payment.
Cash-out refi: almost never right in 2026
A cash-out refinance replaces your entire existing mortgage with a new, larger loan at current market rates. The proceeds fund the renovation. Freddie Mac's average 30-year fixed rate for the week of May 8, 2026 was 6.47% [2].
The problem for most Arizona homeowners: approximately 68% of outstanding Arizona mortgages carry rates below 5%, and 41% carry rates below 4% [7]. A cash-out refi at 6.47% replaces that asset with a significantly more expensive one. On a $400K remaining balance, the payment difference between 3.25% and 6.47% is approximately $650/month — roughly $234,000 in additional interest over 30 years.
When it does make sense: your current mortgage rate is already above 5.5%, and a cash-out refi at today's rates actually improves your rate while pulling renovation equity. Or you're refinancing out of an ARM and the fixed rate is the goal. For the majority of Phoenix-area homeowners who locked rates between 2020-2022, cash-out refi is a costly path to avoid.
FHA 203(k) and Fannie Mae HomeStyle: government-backed renovation mortgages
Both FHA 203(k) and Fannie Mae HomeStyle are post-renovation value products — they size the loan on what the home will be worth after the work is done rather than its current value. That is the right mechanism. The limitation is conforming loan limits.
In Maricopa County, the 2026 conforming loan limit is $766,550 for a single-unit primary residence [6]. For an Arcadia home currently worth $1.2M, neither product will issue a loan in the range needed for a $350,000-$500,000 renovation — the resulting loan amount (current mortgage + renovation draws) would far exceed the conforming cap.
FHA 203(k) also has two variants: the Standard (for projects over $35,000 requiring a HUD Consultant to oversee draws) and the Limited (for projects under $35,000 with simplified administration). The Standard 203(k) requires the HUD Consultant on every draw inspection, which adds $1,000-$2,500 per draw and extends draw timelines. Arizona FHA lenders that offer 203(k): Guild Mortgage, loanDepot, Cardinal Financial, and most local credit unions with FHA designation [3].
HomeStyle is the Fannie Mae equivalent. Higher credit score requirement (680 minimum vs. FHA's 580), but fewer restrictions on project types — HomeStyle allows luxury improvements that FHA prohibits, including pools and landscaping. HomeStyle loans are available from most retail mortgage lenders in Arizona [4].
ARV construction loan: the right tool for major Arizona renovations
The ARV-based construction loan — offered by portfolio lenders including Bell Bank, Western Alliance, and a small number of Arizona private banks — is the product most high-equity Arizona homeowners doing significant renovations have never heard of. It is also, for projects in the $200,000-$2,000,000 range, often the right tool.
Here is the key difference from every other product on this list: the loan is underwritten on the value of the home after the renovation is complete, not its current value. If your home is worth $1.2M today and a $400,000 renovation will bring it to $1.6M, the ARV construction loan sizes the available borrowing against the $1.6M after-repair value rather than the $1.2M current value. That produces meaningfully more loan capacity than a HELOC — and critically, it can be structured as a second lien, leaving your existing first mortgage entirely in place.
How it works mechanically: the construction loan funds in draws as work is completed — the lender sends an inspector (or reviews geo-tagged photo documentation) before releasing each draw payment. Interest accrues only on the drawn amount during construction. At project completion and certificate of occupancy, the construction loan either converts to a permanent mortgage (One-Time Close) or is paid off and replaced by a new permanent loan (Two-Time Close). The Two-Time Close allows scope and rate adjustment at the permanent close — better for large or complex renovations.
The rate is fixed, not variable. May 2026 rates from Bell Bank on ARV Two-Time Close products: 7.25%-7.625% for primary residences under $2M with 740+ FICO [5]. That's higher than a HELOC's opening rate today, but the rate is locked — no prime exposure — and the fixed permanent rate at close is negotiated based on then-prevailing market conditions.
Qualification standards for Arizona portfolio lenders
Portfolio lenders like Bell Bank set their own qualification standards rather than selling to Fannie/Freddie. In practice, the standards for Arizona ARV renovation products in 2026 cluster around the following thresholds, though specific lenders vary [5]:
| Metric | Typical requirement | Notes |
|---|---|---|
| FICO score | 720 minimum; 740+ for best rate | Sub-700 typically declined; 700-720 available at some lenders with compensating factors |
| End LTV (permanent close) | 85% for loans up to $1M; 80% for $1M-$1.5M | Based on after-repair appraised value; the appraisal orders off the proposed plan set |
| Front-end DTI | 30% maximum | Housing payment (PITI on both the construction loan + existing first) / gross monthly income |
| Back-end DTI | 38%–45% depending on loan size | Total debt / gross monthly income; lower caps at higher loan amounts |
| Down payment / equity | 10%–20% of total project cost | Typically contributed from existing equity in the property rather than cash |
| Contractor ROC license | Required; Class B residential | Lender verifies ROC status and bond independently |
| Project documentation | AIA G702 format budget + stamped plan set | Required at application; not at closing — most lenders want these before committing loan terms |
Thresholds above reflect Bell Bank's published lending matrix for primary residences. Private bank portfolio products may vary. Exception approvals are available for strong compensating factors on some metrics — ask the loan officer directly.
Arizona portfolio lenders that offer ARV renovation products
Most national banks and online lenders do not offer ARV-based construction loans — these are portfolio products held on the lender's own balance sheet rather than sold to Fannie Mae or Freddie Mac. In the Phoenix metro as of May 2026, meaningful options include:
- Bell Bank — Phoenix-based, in-house construction lending desk, in-house appraisal, simple draw process. Two-Time Close and One-Time Close available. Stated median close time 9.7 weeks for Two-Time Close in 2025 [5]. GC applications sent to PortfolioRealEstateUnderwriting@bell.bank.
- Western Alliance Bank — Phoenix-headquartered, strong construction and renovation lending division. Private banking relationships for loan amounts over $1.5M.
- Arizona private banks — Signature Bank, National Bank of Arizona (now part of Heartland), and a small number of private banking desks at institutions with Arizona branches. Typically require existing depository relationship.
- RenoFi network — RenoFi is not a lender; it is a marketplace that connects homeowners to a network of approximately 200 credit unions with ARV-based lending capabilities [8]. Lower rate than most portfolio lenders if you qualify through a RenoFi credit union partner, but the underwriting runs through a third party (the credit union) with its own timeline.
RenoFi is worth mentioning specifically because it is the most visible brand in this space nationally, including in Arizona. Their loan amounts are limited by the credit union's conforming-adjacent caps, which can create a ceiling on very large projects. For $300K-$700K renovation projects in Arcadia, a RenoFi partner credit union may be competitive. For $700K+ projects, a full portfolio lender like Bell or Western Alliance is typically the cleaner path.
Arizona credit unions offering renovation loans
Arizona credit unions occupy the top organic positions when Phoenix homeowners search for renovation loans, and for good reason: they offer some of the most competitive HELOC and home equity loan rates in the state, with member-friendly underwriting and local decision-making. If your project is under $250K and your existing equity is sufficient, a local credit union HELOC is worth pricing first.
| Credit union | Products | HELOC rate (May 2026) | Max CLTV | Notes |
|---|---|---|---|---|
| Desert Financial Credit Union | HELOC, Home Equity Loan | 7.24%–7.75% variable | 85% | Largest Arizona-based CU; competitive intro rates, local underwriting |
| OneAZ Credit Union | HELOC, Home Equity Loan | 7.50%–7.99% variable | 85% | Statewide footprint; fast online application; 10-year draw period |
| Arizona Financial Credit Union | HELOC | 7.49%–7.99% variable | 80% | Conservative LTV caps but strong member service; Phoenix metro focus |
| AZ Central Credit Union | HELOC, Home Equity Loan | 7.25%–7.75% variable | 85% | Member-focused pricing; lower rate floors for 750+ FICO borrowers |
| CU West (Arizona) | HELOC | 7.50%–8.25% variable | 80% | West Phoenix and suburban service area; flexible use of funds during draw period |
Rates as of May 2026 and subject to change. All products are current-value HELOC/HEL — they lend against your home's existing equity, not after-repair value. For projects requiring more capacity than existing equity supports, see the ARV construction loan section above.
The structural limitation that applies to all credit union HELOC products: they size the loan on your home's current value, not its post-renovation value. If you have a $1.2M home with $350K remaining on the mortgage, the maximum combined debt at 85% CLTV is $1.02M — leaving $670K of theoretical availability. That's sufficient for many projects. If your renovation exceeds that capacity, or if you need a fixed-rate product, you'll need to step up to an ARV construction loan from a portfolio lender.
For any ARV construction loan, the documents you need before submitting an application:
- Income documentation: Last two years W-2s, last two years tax returns, three months pay stubs, employer verification letter. Self-employed borrowers: two years of business and personal returns, YTD P&L.
- Asset documentation: Two to three months bank statements. Any deposit over $2,500 that isn't clearly payroll will require a source-of-funds letter. Gift money from family requires a notarized gift letter and the donor's bank statement showing the funds.
- Property documentation: Current mortgage statement, homeowner's insurance policy, HOA documents if applicable.
- Project documentation: Contractor ROC license and certificate of insurance, AIA G702-format line-item budget, stamped architectural plan set (or preliminary design if the full plan set isn't ready — some lenders will issue a conditional approval before plans are finalized).
- Appraisal: The lender orders this, not you. For an ARV appraisal, the appraiser reviews the proposed plan set and budget and produces a "subject-to" value — the home's projected market value assuming the renovation is completed as described. Allow 7-12 business days for the in-house appraisal desk at portfolio lenders; independent renovation appraisers in Phoenix have 4-8 week wait times.
The single most predictable point of failure in the lender intake process: the contractor's budget format. Most contractors who have only worked on cash-paid projects have never produced an AIA G702 budget. The reformatting takes 3-7 days and creates a week's delay in the application review. Ask for the G702 format explicitly at the first contractor meeting, not at the time of financing.

The renovation financing decision in one question
The question that determines the right product: what is your current mortgage rate?
- Below 5%: Don't touch the first mortgage. HELOC for projects under $200K; ARV construction loan in second position for projects over $200K. The rate asset in your existing mortgage is worth $50,000-$150,000 in present value depending on balance and rate — it should be preserved unless there's a compelling reason not to.
- 5%–6.5%: The math is closer. A HELOC or ARV second-lien product is still generally the better path, but a cash-out refi becomes less costly than it would be for a 3% borrower. Run the actual numbers for your specific balance and rate.
- Above 6.5%: Cash-out refi or a first-lien ARV construction product may actually improve your rate while funding the renovation. Worth a full analysis.
If you're in the first category — the majority of Arizona homeowners who locked rates in 2020-2022 — the ARV construction loan in second position is, for projects in the $200K-$2M range, usually the best tool available. It funds the renovation, leaves the first mortgage intact, and is sized against what you're building toward rather than where you started.
