How Much Home Equity Do You Actually Have? (And How to Use It)

By Cameron Wilson ·
TL;DR

Home equity = your home's current market value minus what you still owe on it. Most homeowners underestimate theirs because they rely on Zestimates instead of an actual market analysis. Equity matters because it's what funds your next move — through a sale, a HELOC, a cash-out refinance, or a program like Equity Move.

What is home equity?

Home equity is the portion of your home’s current market value that you actually own outright. The formula:

Home equity = current market value − total amount owed on the home

If your home is worth $500,000 and you owe $300,000 on the mortgage, you have $200,000 in equity.

How do I figure out what my home is actually worth?

Three sources, ranked by reliability:

  1. A comparative market analysis (CMA) from a local agent. Free, takes a few days, and is grounded in recent comparable sales the agent has actually walked through. This is the gold standard short of a paid appraisal.
  2. A formal appraisal. ~$500–700, used for refinances and program qualification. Most rigorous, but rarely necessary just to know roughly where you stand.
  3. Online estimates (Zestimate, Redfin Estimate, Realtor.com). Free and instant, but the median error is 2–7% and can be much higher for renovated, oversized, or unusual homes. Useful as a starting point — risky as a basis for decisions.

For decisions that involve real money, never rely on a Zestimate alone.

How do I figure out what I owe?

Log into your mortgage servicer’s portal and check the current principal balance. Don’t use the original loan amount — you’ve been paying it down. If you have a HELOC or second lien, add those balances too.

Why does my equity number matter for moving?

Your equity is, in practical terms, the down payment on your next home. It’s also the determining factor for:

Four ways to put equity to work

OptionWhen it fitsWatch out for
SellMoving to a new home, downsizing, relocatingTransaction costs (~6–8% of sale price)
HELOCNeed flexibility, want to keep the homeVariable rates, short draw period
Cash-out refinanceWant a lump sum at a fixed rateResets your mortgage clock; rate may be higher than current
Equity Move programWant to buy next home before selling currentProgram fees; sell-side timeline still applies

Frequently asked questions

How accurate is a Zillow Zestimate?

Zillow's published median error rate is around 2% for on-market homes and 7% for off-market homes — but the error in either direction can be much larger for unique properties. A local agent's comparative market analysis (CMA) is typically more accurate because it accounts for condition and recent comparable sales the algorithm doesn't see.

Can I access my home equity without selling?

Yes — common options are a HELOC (revolving line), a home equity loan (lump sum), or a cash-out refinance (replaces your mortgage). Each has different rate structures, payback timelines, and tax implications.

What's the difference between equity and home appreciation?

Appreciation is the increase in your home's market value. Equity is appreciation plus the principal you've paid down on your mortgage, minus any liens. You can have meaningful equity even if your home hasn't appreciated, just from years of mortgage payments.
