HELOC vs. HELOAN: what's the difference?
Both let you borrow against your home's equity while keeping your existing first mortgage — useful when you have a low first-mortgage rate you don't want to lose. A HELOC (home equity line of credit) is a revolving line with a variable rate: you draw what you need during a draw period, often paying interest-only at first, then repay over an amortizing term. A HELOAN (home equity loan) is a fixed-rate lump sum at closing with predictable payments — closer to a traditional installment loan.
HELOCs suit ongoing or uncertain costs (a phased remodel, a cushion) and reward discipline, since the variable rate can move. HELOANs suit a known, one-time expense where a fixed payment matters. Both typically allow up to about 90% combined loan-to-value (CLTV). The calculator above runs your numbers through both so you can compare max access, monthly cost, and the full payment breakdown. If you'd rather pull cash by replacing your first mortgage, see the cash-out refinance calculator.
Common questions
Which is cheaper, a HELOC or a HELOAN?
It depends on rates and how you'll use the money. HELOCs often start with a lower variable rate and interest-only draws, but the rate can rise; HELOANs lock a fixed rate for the life of the loan. For a known one-time cost, a HELOAN's certainty often wins; for flexible, ongoing needs, a HELOC can cost less if rates stay steady.
How much can I borrow with a HELOC or HELOAN?
Most lenders allow up to about 90% of your home's value across all liens (combined LTV). Your available amount is roughly that cap minus your current mortgage balance. Your credit band affects both eligibility and rate — the calculator estimates this for you.

San Diego is California's second-largest city, where limited coastal land and steady demand keep home prices among the highest in the nation, well above $900,000 by most 2026 measures. The housing stock spans dense downtown condos and townhomes, classic Craftsman and Spanish-style bungalows in older neighborhoods, and newer master-planned communities inland that may carry Mello-Roos special assessments on top of the base property tax. Because typical prices sit near or above the county's conforming loan ceiling, many local buyers encounter jumbo financing, larger down-payment expectations, and wildfire- and earthquake-related insurance considerations. Understanding local property taxes, loan limits, and hazard coverage is essential before shopping for a home in the San Diego area.
Why insurance moves the number here: Much of San Diego's inland, foothill, and canyon-adjacent development sits in or near Wildland-Urban Interface areas, and the city and CAL FIRE/state fire marshal designate Very High Fire Hazard Severity Zones across parts of the city and county. As traditional insurers have pulled back from coastal-California wildfire exposure, some owners turn to the California FAIR Plan, the state's insurer of last resort for basic fire coverage, typically pairing it with a wrap-around (difference-in-conditions) policy for perils it excludes. San Diego also carries seismic risk from the Rose Canyon Fault, a strike-slip fault that runs onshore near downtown and is considered capable of a large, damaging earthquake. Low-lying and coastal areas can additionally face flood exposure, so buyers should check FEMA flood maps and local hazard designations for a specific address. Wind exposure is a large part of why a San Diego payment can differ from the same price elsewhere, so the insurance figure above is doing real work in the total.
Median value plus the county property-tax rate and statewide insurance figure come from public data held in this site’s own dataset. Payments use an illustrative 6.875% 30-year rate and are estimates for education only — never a quote, offer, or approval. Change any input in the calculator above to model your own scenario.
