How much can I borrow against my home equity?
Most lenders allow you to borrow up to 80% of your home's current value across all mortgage debt combined (combined LTV). Subtract your existing mortgage balance from that figure to find the maximum cash available. Business owners can access equity via cash-out refi, HELOC, or home equity loan.

The CLTV calculation
What you need to know
- Standard max CLTV: 80% of appraised home value across all liens
- Formula: (Home value × 0.80) − existing mortgage = maximum tappable equity
- Use the equity calculator to estimate your specific numbers
- HELOC, cash-out refi, or home equity loan — different structure, same CLTV math
- Non-QM programs may allow up to 85–90% CLTV for qualified borrowers
- Appraisal required: lender uses a new appraisal, not estimated/Zillow value
About this
Running the CLTV math
Start with your home's current appraised value (not your purchase price, not Zestimate — the lender orders a fresh appraisal). Multiply by 0.80 for the standard 80% CLTV limit. Subtract your existing mortgage balance. The result is the maximum amount of equity debt the lender will add to the property.
On a $900,000 home with a $400,000 mortgage: ($900,000 × 0.80) − $400,000 = $720,000 − $400,000 = $320,000 in available equity.
Choosing the right equity product
Three equity products access the same pool of equity through different structures. A cash-out refinance replaces your existing mortgage with a new, larger one — one loan, one payment, but you restart the amortization clock. A HELOC sits behind your existing mortgage as a second lien — a revolving line you draw on as needed. A home equity loan (also a second lien) disbursed a fixed lump sum at a fixed rate.
Income qualification for equity products
All equity products require income qualification. For self-employed borrowers, that means bank statements, 1099s, or a CPA P&L — the same documentation programs used for purchase financing. Rental income on investment properties can qualify under DSCR for a DSCR cash-out refinance.
Using the equity calculator
The equity calculator at /calculators/equity/ computes your estimated tappable equity at various CLTV thresholds. It's an estimate — the actual lender uses an ordered appraisal. Plug in your current estimated value, mortgage balance, and target CLTV to see what's available before you start the formal process.
Common questions
- Can I access equity without refinancing my existing mortgage?
- Yes — a HELOC or home equity loan sits behind your existing mortgage as a second lien. You keep your current first mortgage (and its rate) while accessing equity through the second lien product.
- Does my credit score affect how much equity I can access?
- Yes. Higher credit scores enable higher CLTV limits and better rates on equity products. Some programs allow 85–90% CLTV at 720+ credit; others cap at 80% CLTV at lower scores. The equity calculator uses 80% as a conservative default.
- Can I use a bank statement loan for a cash-out equity access?
- Yes — a bank statement cash-out refi qualifies on business deposits without tax returns. The CLTV math is the same; the income qualification uses the same 12–24 month deposit averaging methodology.
- What happens to my equity access if home prices fall?
- A lower appraised value reduces the CLTV ceiling and therefore the available equity. If you're on a HELOC, the lender can reduce your credit line if the appraised value drops below the line's collateral requirement.
- How long does it take to access equity?
- A HELOC or home equity loan typically closes in 2–4 weeks. A full cash-out refi takes 3–6 weeks. Rush timelines are possible in some circumstances. Start the process before the capital need is urgent.
