Arizona Home Equity Calculator: How Much Can You Borrow? (2026)
The Scout Executive Summary
- Total vs. Accessible Equity: Your total equity is your home value minus mortgage balances. However, accessible (or tappable) equity is what a lender actually lets you borrow, determined by CLTV limits.
- Arizona CLTV Limits: Most Arizona lenders allow you to access up to 80%–85% of your home’s value minus your existing mortgage.
- The Math: On a $900,000 Scottsdale home with a $500,000 mortgage, you have $220,000 to $265,000 in accessible equity.
- Market Growth: Arizona homeowners who bought before 2022 often have more equity than they realize. Many Phoenix Valley homeowners are sitting on $250,000 to $400,000 in tappable equity thanks to recent appreciation.
Before you can decide what to do with your home equity, you need to know how much you actually have, and how much of it a lender will let you access. For Phoenix Valley homeowners, the answer may be significantly larger than you expect.

How Do You Calculate Your Home Equity in Arizona?
To calculate your home equity, you take your current home value and subtract your total mortgage debt (what you still owe on your mortgage).
So if your home is worth $850,000 and you owe $480,000 on your mortgage, your equity is $370,000. If you have both a first mortgage and an existing HELOC or home equity loan, both balances count.

A Simple Arizona Example
| Item | Amount |
|---|---|
| Current appraised value | $850,000 |
| First mortgage balance | $480,000 |
| Existing HELOC balance | $0 |
| Total home equity | $370,000 |
That $370,000 is your total equity, but a lender won’t let you borrow all of it. How much you can use depends on your CLTV, explained next.
What Is CLTV, and Why Can’t You Borrow All of Your Equity?
CLTV, or combined loan-to-value, is the share of your home’s value that all of your home loans add up to, and lenders use it to set your borrowing limit.
See what your equity could cover. Check your HELOC rate online.
To find it, add up everything you owe on the home, including your first mortgage and any HELOC or home equity loan you already have. Then divide by the home’s value. On an $850,000 home with a $480,000 mortgage, your CLTV today is about 56%.
Most HELOC lenders won’t let that number go above 80% or 85% once the new line is added. That leaves a cushion of equity in the home in case prices drop. For lender-by-lender Arizona caps, see How Much Home Equity Do You Need for a HELOC in Arizona?
How Much of Your Equity Can You Actually Borrow?
You can usually borrow your home’s value times your lender’s CLTV limit, minus what you already owe.

Follow these 3 steps to calculate your accessible equity:
- Determine your home’s current value (e.g., $850,000).
- Multiply by the lender’s CLTV limit (e.g., 0.80 or 0.85).
- Subtract your current mortgage balance (e.g., $480,000) to find your accessible equity.
Examples using the $850,000 Scottsdale home:
| CLTV Limit | Calculation | Accessible Equity |
|---|---|---|
| 80% | ($850,000 x 0.80) – $480,000 | $200,000 |
| 85% | ($850,000 x 0.85) – $480,000 | $242,500 |
On this home, the gap between an 80% lender and an 85% lender is $42,500, so compare limits before you apply.
Scout’s Tip
Your CLTV can change your rate, not just your limit. Many lenders price a line at 80% CLTV lower than one at 85% or 90%, so borrowing a little less can cost less every month. Check this month’s numbers on our Arizona Home Equity Rates page.

What Is Your Arizona Home Worth Right Now?
Your home’s value moves your equity more than anything else, and you can estimate it three ways, from free and rough to paid and precise.
Thinking about unlocking your home’s equity? Find your rate online.
- Automated Valuation Model (AVM): Free tools like Zillow’s Zestimate or Redfin’s estimate use recent sales data. Useful as a benchmark but can miss by a wide margin on high-end or one-of-a-kind homes, where few similar homes have sold recently.
- Comparative Market Analysis (CMA): A licensed Arizona Realtor provides a free CMA using actual recent comparable sales. More accurate than an AVM for Scottsdale and Fountain Hills properties where lot size, view corridors, and HOA community matter.
- Formal appraisal: A licensed Arizona appraiser provides the most accurate value. Cost: $400 to $700 for a standard Phoenix Valley home. Most Arizona HELOC lenders order their own appraisal or AVM during underwriting.
How Has Phoenix Valley Appreciation Changed Your Equity?
If you bought your Arizona home before 2022, rising prices have likely added more to your equity than your mortgage payments have.

Per ARMLS Q2 2026:
| ZIP and Area | Q2 2026 Median | YoY Change |
|---|---|---|
| 85255 (DC Ranch, Silverleaf) | $1,450,000 | +8.2% |
| 85258 (McCormick Ranch) | $1,050,000 | +20.7% |
| 85268 (Fountain Hills) | $722,500 | +1.0% |
| 85254 (Paradise Valley corridor) | $950,000 | +3.3% |
Here’s how that plays out. Say you bought a Phoenix Valley home in 2020 for $600,000, it’s worth $800,000 today, and you owe $430,000. Your total equity is $370,000. At 80% CLTV you could tap about $210,000, and at 85% about $250,000. (Illustration only. Your numbers depend on your home and your lender.)

How Much Could You Get From an HEI Instead?
An HEI can give you cash when a HELOC won’t, but it measures your equity differently.
Instead of a CLTV cap, HEI companies look at how much equity you’ll have left after funding, and most also limit the cash to a percentage of your home’s value. There are no monthly payments, so your income matters less than it does for a HELOC. When the term ends or you sell, you settle with the company by paying it a share of your home’s value at that time.
Curious if an HEI is right for your situation? Check your estimate with no credit impact.

Scout’s Tip
If a lender’s CLTV cap leaves you short, or your credit keeps you out of a HELOC, an HEI is worth a look. Both Nada and Splitero let you check eligibility online with no monthly payments.
What Can Lower the Amount a Lender Offers You?
Your real offer can come in below your calculator estimate, and it usually happens for one of four reasons.
Want a real number, not an estimate? Check your rate in minutes.
- A lower appraisal: The lender’s appraisal or valuation may come in under your online estimate, and every dollar less in value is a dollar less you can borrow.
- Your credit score: Some lenders allow a higher CLTV only for stronger scores. See Arizona HELOC equity requirements for how caps change.
- Your debt-to-income ratio (DTI): This compares your monthly debt payments with your income. If it’s too high, a lender may approve a smaller line than your equity allows.
- Other liens or property type: A second mortgage, judgment or other lien counts against your CLTV, and condos and some other property types can face tighter rules. See HEIs on condos and townhomes.
Which Equity Access Option Fits Your Situation?
A HELOC fits most people who want flexible access, but the right choice depends on how you’ll use the money and whether you can qualify.
Curious if a HELOC fits your budget? Estimate your rate today.
| Your Situation | Best Option | Why |
|---|---|---|
| Need flexible access over time | HELOC | Draw only what you need, pay interest on drawn amount |
| One-time expense, want fixed rate | Home equity loan | Lump sum, fixed rate, defined payoff |
| Cannot qualify for HELOC | HEI | Approval leans more on equity than credit; no monthly payments |
| Age 62+, want no monthly payment | HECM reverse mortgage | No payment required while in home |
| Above HECM limit, high-value property | Jumbo reverse mortgage | Higher limits than a standard HECM for high-value homes |

Common Questions About Calculating Arizona Home Equity
Subtract your total mortgage balance from your home’s current market value. If your home is worth $850,000 and you owe $480,000, your equity is $370,000. Subtract any second lien balances as well. Your accessible equity is lower, based on the lender’s CLTV limit, typically 80% to 85%.
Most Arizona HELOC lenders cap your combined loan-to-value at 80% to 85%. On an $850,000 home with a $480,000 mortgage, that means about $200,000 at 80% and $242,500 at 85%. Your credit, income and the lender’s appraisal can lower that number.
Start with a free AVM from Zillow or Redfin as a benchmark. For a more accurate estimate in Scottsdale’s luxury market, request a free CMA from a licensed Arizona Realtor. For the most precise figure, a formal appraisal costs $400 to $700.
Mortgage holders with borrowable equity averaged about $212,000 in Q2 2026, according to ICE’s August 2026 Mortgage Monitor. That counts what they could borrow while keeping 20% equity in the home. Arizona homeowners who bought before 2022 may have more, depending on purchase price and how much they still owe.
No. A HELOC uses a portion of your equity up to the lender’s CLTV limit, typically 80% to 85%. The remaining equity stays in your home. You only make payments on the amount you actually draw, not the full approved credit limit.
Every dollar of appreciation increases your equity dollar for dollar. A Phoenix Valley home that appreciated from $800,000 to $900,000 added $100,000 to equity with no mortgage paydown. At 80% CLTV, that appreciation added $80,000 to your accessible HELOC limit.
Your equity drops dollar for dollar with your home’s value. If values fall significantly, your lender can freeze your HELOC or lower your limit even if you still have equity left, because federal lending rules allow it. Read more in Arizona HELOC Risks.
No. Equity isn’t income, and money you borrow through a HELOC or home equity loan isn’t taxable income either. HEI cash works differently because it isn’t a loan, so ask a tax professional how it applies to you. HELOC interest may be deductible if you use the money to buy, build or substantially improve the home. See the full HELOC tax deductibility guide.
