What Is Home Equity, and How Much Do You Have?
Home equity is the difference between what your home is worth and what you still owe on it. If your Arizona home is worth $500,000 and you owe $300,000, you have $200,000 in equity. After years of strong appreciation across the Phoenix metro and greater Arizona, many homeowners are sitting on far more equity than they realize — and both a HELOC and a home equity loan let you borrow against it without selling or disturbing your existing mortgage.
The key number lenders use is combined loan-to-value (CLTV): your existing mortgage plus the new loan, divided by the home's value. Most Arizona lenders cap CLTV at 80%–90%, which determines your maximum borrowing power. Not sure what your home is worth today?

HELOC vs. Home Equity Loan
Both are second liens on your home, but they behave very differently.
| Feature | HELOC (Line of Credit) | Home Equity Loan (Lump Sum) |
|---|---|---|
| Structure | Revolving credit line you draw from as needed | One lump sum at closing |
| Rate | Usually variable | Usually fixed |
| Payments | Interest-only during draw period, then principal + interest | Fixed principal + interest from day one |
| Best for | Ongoing or uncertain costs (phased remodel, tuition over time) | One-time known cost (debt payoff, single project) |
| Flexibility | High — borrow, repay, reborrow during draw period | Low — fixed amount, fixed schedule |
| Payment predictability | Lower — payment and rate can change | Higher — same payment every month |
A simple way to choose: if you know the exact amount and want a locked payment, the home equity loan wins. If you want a flexible reserve to draw on over time, the HELOC wins. Many Arizona homeowners use a HELOC as a standing safety net even when they don't draw on it immediately.
How Much Can You Borrow in Arizona?
Your maximum is set by CLTV. Here's how it works on a home worth $500,000:
| Max CLTV | Total allowed debt | Minus $300k mortgage | Available to borrow |
|---|---|---|---|
| 80% | $400,000 | −$300,000 | $100,000 |
| 85% | $425,000 | −$300,000 | $125,000 |
| 90% | $450,000 | −$300,000 | $150,000 |
Higher CLTV limits typically require stronger credit, lower debt-to-income, and a primary residence. Investment properties usually cap lower (often 70%–75%). The exact ceiling depends on the lender, so having access to multiple sources matters.
Requirements to Qualify
- Equity: generally at least 15%–20% remaining after the new loan (i.e., CLTV of 80%–85%)
- Credit score: most lenders want 680+, best rates at 720+
- Debt-to-income: typically 43%–50% or lower, including the new payment
- Income & employment: documented and stable; self-employed borrowers can qualify (see below)
- Appraisal: to confirm current value and your available equity
HELOC vs. Cash-Out Refinance
This is the decision that trips up most Arizona homeowners, and it usually comes down to your existing mortgage rate.
| Your situation | Better choice | Why |
|---|---|---|
| Low fixed rate on current mortgage | HELOC / home equity loan | Keeps your low first-mortgage rate untouched; only adds a second lien |
| Current rate at or above market | Cash-out refinance | Replace the whole loan and pull equity in one move |
| Want flexibility / reserve | HELOC | Draw only what you need, when you need it |
| Want one predictable payment | Cash-out refi or home equity loan | Single fixed payment |
Because so many Arizona homeowners locked in low rates in prior years, tapping equity via a HELOC rather than refinancing the whole mortgage is often the far cheaper path today. The full refinance math — break-even, rate-and-term vs. cash-out — is in our Arizona refinancing pillar guide.
Smart (and Risky) Ways to Use It
Generally smart: value-adding home renovations (which may also make the interest deductible), consolidating high-interest credit card debt into a lower-rate secured loan, funding a home purchase down payment, or keeping a standing HELOC as an emergency reserve. Renovation-minded borrowers should also compare against a dedicated renovation loan, which lends on after-improved value.
Higher risk: using home equity for depreciating purchases (cars, vacations) or to cover ongoing living expenses — because you're securing that debt with your house. A HELOC's variable rate also means payments can rise, so build in a cushion. As always, borrow against equity with a clear repayment plan, not as a way to stretch a budget that's already tight.

Frequently Asked Questions
What's the difference between a HELOC and a home equity loan?
A HELOC is a revolving, usually variable-rate line of credit you draw from as needed, paying interest only on what you use. A home equity loan is a fixed-rate lump sum with predictable payments. HELOCs suit ongoing or uncertain costs; home equity loans suit a one-time known expense.
How much can I borrow in Arizona?
Typically up to 80%–90% of your home's value minus your existing mortgage (your CLTV). On a $500,000 home with a $300,000 mortgage at 85% CLTV, that's about $125,000. Strong credit and low debt-to-income push toward the higher end.
What credit score do I need?
Most Arizona lenders want around 680 minimum, with the best rates at 720+. Lower scores can work with more equity and lower debt-to-income, but expect higher rates.
Is the interest tax deductible?
Generally only when the funds buy, build, or substantially improve the home securing the loan, within mortgage-interest limits. Other uses typically aren't deductible. Todd is a mortgage lender, not a tax advisor — confirm with a tax professional.
Should I get a HELOC or a cash-out refinance?
If your existing mortgage has a low fixed rate, a HELOC or home equity loan usually wins by leaving that rate untouched. A cash-out refinance mainly makes sense when your current rate is at or above today's market.
Can I get a HELOC on an investment property?
Yes, some Arizona lenders offer them, but with stricter terms — lower max CLTV (often 70%–75%), higher rates, and stronger credit and reserve requirements than on a primary residence.
