What Is Equity?
Equity is what you'd walk away with if you sold the property and paid off the mortgage. A $200,000 house with a $150,000 loan has $50,000 in equity. It grows two ways: as you pay down the loan (principal paydown) and as the property appreciates. For investors, forced appreciation through renovations can add tens of thousands in equity in 6–12 months—that's the engine behind BRRRR refinancing.
Equity is the portion of a property's value you own outright—the property's value minus any loans secured against it.
At a Glance
- What it is: The portion of a property's value you own outright—value minus loan balance.
- Why it matters: Equity is your wealth position in the property and your cushion if values drop.
- How it's calculated: Equity = Property Value − Loan Balance (or: Equity = (1 − LTV) × Value).
- Where investors use it: Deal analysis, refinance math, 1031 exchange planning, portfolio net worth.
- Key risk: Equity is illiquid until you sell or refinance—and refinancing converts it to debt.
How It Works
Equity answers one question: how much of this property do I actually own?
The basic math. You buy a $180,000 duplex in Memphis with $45,000 down. Your loan is $135,000. Equity at purchase: $45,000. Five years later, you've paid down $8,000 in principal and the property appraises at $210,000. Your loan balance is now $127,000. Equity: $83,000. That $38,000 gain came from $8,000 in paydown and $30,000 in appreciation.
Two engines of growth. Principal paydown happens every month—your tenant's rent pays the mortgage, and a slice of that payment chips away at the loan. Appreciation happens when the market rises or when you create value through renovations. Forced appreciation is the active investor's edge: a $120,000 property you renovate to appraise at $175,000 creates $55,000 in equity in under a year. Market appreciation alone might take a decade to do that.
The LTV connection. At 75% LTV, you have 25% equity. LTV and equity are inverse—the lender's slice versus yours. When you refinance at 75% LTV on a higher appraisal, you're pulling out equity as cash. That's capital recovery in BRRRR.
Why cash-on-cash return misses it. CoC measures cash flow only. It ignores the equity your tenant is building for you (principal paydown) and any appreciation. A property with modest CoC can still be a strong total return if equity builds 4–5% annually.
Real-World Example
You buy a 3-bedroom in Indianapolis for $142,000 with $35,500 down (75% LTV). Loan: $106,500 at 7% for 30 years. Equity at close: $35,500.
Year 1: You spend $28,000 on a kitchen update, bathroom refresh, and flooring. The property appraises at $185,000. Your loan balance is $105,200 (principal paydown: $1,300). Equity: $79,800. You've created $44,300 in equity—$28,000 from forced appreciation and $16,300 from the value jump beyond your rehab spend.
You refinance at 75% LTV: $138,750 loan. You pay off the old loan and pocket $33,550. Capital recovered. Equity after refinance: $46,250 (the 25% you kept). Your tenant keeps paying down that new loan—equity grows again from there.
Pros & Cons
- Builds automatically through principal paydown—your tenant pays your mortgage.
- Grows faster with forced appreciation—renovations compress years of market gains into months.
- Acts as a cushion—at 25% equity, the market can drop 25% before you're underwater.
- Can be tapped via refinance or HELOC for the next deal.
- Moves tax-deferred with a 1031 exchange when you sell.
- Illiquid until you sell or refinance—you can't spend it without converting to cash or debt.
- Refinancing to tap equity increases your loan balance and monthly payment.
- Appreciation isn't guaranteed—markets can flatline or decline.
- Principal paydown is slow in early years—most of the payment goes to interest.
Watch Out
- Appraisal risk: Your equity exists on paper until you sell or refinance. A low appraisal at refinance time shrinks the equity you can pull out—and your ARV estimate might not match the appraiser's comps.
- Over-leverage trap: At 90% LTV, you have 10% equity. A 15% market dip puts you underwater. Thin equity means no cushion for vacancy, repairs, or a forced sale.
- Refinance timing: Pulling equity out via refinance resets your loan term and can raise your payment. Run the DSCR math—will the property still cash-flow after you take cash out?

The Takeaway
Equity is your ownership stake in the property—the gap between what it's worth and what you owe. It grows through paydown and appreciation, and forced appreciation lets you create it on your timeline instead of waiting for the market. Target 25% equity (75% LTV) on rentals for a solid cushion—and when you've built more through renovations, that's the equity you refinance out to fund the next deal.
