How Much Home Equity Do I Have in Arizona? Calculate It in 2026
The Scout Executive Summary:
- Your total equity is simple to calculate: current home value minus all mortgage balances. The harder number is accessible equity: what a lender will actually let you borrow, which depends on your CLTV limit.
- Most Arizona lenders allow access to 80%–85% of your home’s value minus your existing mortgage. On a $900,000 Scottsdale home with a $500,000 mortgage, that means $220,000 to $265,000 in accessible equity.
- Arizona homeowners who bought before 2022 may have significantly more equity than they realize. North Scottsdale’s 85255 ZIP posted 8.2% year-over-year appreciation in Q1 2026 per ARMLS. Many Valley homeowners are sitting on $200,000 to $400,000 in tappable equity.
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 Home Equity in Arizona?
The formula is straightforward:
Home Equity = Current Home Value – Total Mortgage Debt
If your home is worth $850,000 and you owe $480,000, 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 not all of it is accessible. Lenders cap how much you can borrow based on your Combined Loan-to-Value ratio (CLTV). Understanding the difference between total equity and accessible equity is the most important step in this calculation.
How Much of Your Equity Can You Actually Borrow?
Lenders use CLTV to determine the maximum borrowable amount. Most Arizona HELOC lenders cap at 80% to 85%.
The accessible equity formula: (Home value x CLTV limit) – Mortgage balance = Maximum 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 |
At Arizona Central Credit Union’s 85% CLTV limit, this homeowner accesses $42,500 more than at lenders capped at 80%.
Monthly interest-only payment estimates per $50,000 drawn:
- At 7.00% APR: approximately $292/month
- At 7.25% APR: approximately $302/month
- At 7.75% APR: approximately $323/month

What Is Your Arizona Home Worth Right Now?
Your home value estimate is the most important input in the equity calculation. In Arizona’s active market, many homeowners are working with an outdated number.
Three ways to get a current estimate of your home’s value:
Automated Valuation Model (AVM): Free tools like Zillow’s Zestimate or Redfin’s estimate use recent sales data. Useful as a benchmark but can be 5% to 15% off in Scottsdale’s luxury market where comparable sales are less frequent.
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 Position?
Arizona homeowners who purchased before 2022 have seen significant appreciation that has often increased their equity far beyond their original expectations.
Per ARMLS Q1 2026:
| ZIP Code | Area | Q1 2026 Median | YoY Change |
|---|---|---|---|
| 85255 | DC Ranch, Silverleaf | $1,450,000 | +8.2% |
| 85258 | McCormick Ranch | $1,250,000 | +20.7% |
| 85268 | Fountain Hills | $722,500 | +1.0% |
| 85254 | Paradise Valley corridor | $985,000 | +4.2% |
What this means for a homeowner who bought in 2020: A Scottsdale home purchased in 85255 for $750,000 may be valued at $1,100,000 or more today. With a remaining mortgage of $550,000, that homeowner has approximately $330,000 to $385,000 in accessible equity, often significantly more than they realize.

Which Equity Access Option Fits Your Situation?
Once you know your accessible equity, the next question is how to access it. The right product depends on how you want to use the funds and your financial profile.
| 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 | No credit score minimum at Point and Unlock |
| Age 62+, want no monthly payment | HECM reverse mortgage | No payment required while in home |
| Above HECM limit, high-value property | Jumbo reverse mortgage | Calculates on full appraised value |

Arizona Home Equity Calculations: Common Questions
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 allow a maximum CLTV of 80% to 85%. On a $900,000 Scottsdale home with a $500,000 mortgage, the 80% CLTV limit provides up to $220,000 in accessible equity. Arizona Central Credit Union’s 85% limit provides up to $265,000 on the same property.
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.
According to Bankrate, the average American homeowner holds approximately $213,000 in tappable equity as of early 2026. For Scottsdale and North Phoenix Valley homeowners who purchased before 2022, tappable equity is often $300,000 to $500,000 given the appreciation cycle.
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 Scottsdale 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 decreases dollar for dollar with any home value decline. If values fall enough to push your CLTV above 100%, you are in negative equity and a HELOC may be frozen or unavailable.
No. Home equity is not taxable income. Borrowing against equity through a HELOC, home equity loan, or HEI does not generate taxable income. HELOC interest may be tax deductible if funds are used to substantially improve the home. See the full HELOC tax deductibility guide.
