Short answer: a home equity loan is a lump-sum loan secured by the equity in your home. It usually sits as a second lien behind your first mortgage, typically carries a fixed interest rate, and is repaid in fixed monthly payments over a set term — commonly 5 to 30 years. You receive the full amount at closing and pay interest on all of it from day one. Lenders typically cap combined loan-to-value — your first mortgage plus the new loan, against the home's value — at around 80–85%, though the cap varies by lender, and the value they lend against comes from the lender's own appraisal, not an online estimate.
A home equity loan — often called a second mortgage — is a loan from a bank, credit union or mortgage lender, secured by your home. You apply, the lender underwrites your income, credit and debts, orders an appraisal of the home, and at closing pays you the full loan amount in one lump sum. From the first month you repay principal and interest in a fixed payment that does not change if the rate is fixed, which it typically is. Because the home is the collateral, the rate usually sits below unsecured borrowing like credit cards or personal loans — and because the home is the collateral, failing to pay puts the home itself at risk of foreclosure. The first mortgage is untouched: its rate, payment and balance stay exactly as they were.
The ceiling is your equity run through the lender's cap. Equity is your home's value minus everything you owe on loans secured by it. Most lenders cap the combined loan-to-value — first mortgage plus the new loan, divided by the appraised value — at roughly 80–85%, and the cap each lender uses is theirs. One labeled example, with round numbers to show the shape only: on a $400,000 appraised value at an 80% cap, total borrowing tops out at $320,000; with $240,000 still owed on the first mortgage, the largest home equity loan is about $80,000, before closing costs. Your own numbers are the ones in Homeowner HQ — your tracked value and what you owe — and the lender's appraisal and underwriting have the final say.
Three products borrow against the same house and are easy to confuse. A home equity loan pays one lump sum, typically at a fixed rate, and the repayment clock starts immediately on the full amount. A home equity line of credit (HELOC) is a revolving line you draw from as needed over a draw period, typically at a variable rate, paying interest only on what you have actually drawn. A cash-out refinance does not add a second loan at all — it replaces your first mortgage with a larger one and pays you the difference, re-pricing your entire balance at the new loan's rate. Which fits is mostly about the shape of the spending: one known cost favors the loan, staged or uncertain spending favors the line, and a first mortgage worth replacing anyway is the only case where the refinance competes.
Price the whole loan, not the rate alone: closing costs — application, appraisal, title and recording charges — are real money on a second lien, and interest runs on the full lump sum from the day of closing, so borrowing early for a project that starts in a year pays a year of interest on money sitting in a checking account. The deeper cost is the collateral: a home equity loan converts ordinary spending into a lien on the home, and a missed-payment spiral ends at foreclosure, not at a collections call. The fixed payment is the product's virtue — predictable, closed-end, finished on a known date — and it is bought by giving up the HELOC's pay-only-on-what-you-use flexibility. Borrow against equity for things that outlast the loan, and let the payment fit the budget with room to spare.
A home equity loan has nothing to do with what your home is worth, and Homeowner HQ does not lend. Your tracked value and equity are preparation: they show you where you stand before a lender runs its own numbers. The lender's appraisal is the value the loan is actually underwritten on, and it can land above or below any estimate — the estimate's job is to keep you from being surprised, and a record corrected with your home's real facts is the best preparation you can hand an appraiser.
Your own agent sends a monthly value update from Homeowner HQ — the estimate, labeled as an estimate, with your equity beside it — and HQ runs on Amazon AWS. The equity line is the number this loan is built on: when you take a loan secured by your home, or pay one down, the amount you owe changes, so tell your agent or correct the fact in HQ and the updates after that show the equity you actually have. Realtors and lenders use the same HQ together: homeowners stay connected to their own agent, and the monthly trend is the honest way to watch the number a lender will test.
Homeowners are always free. Realtors pay $25/mo to join and lenders join at the $5/mo founding rate, at any book size, with no setup fee; sending messages inside HQ is a $100/mo unlock ($125/mo total for realtors, $105/mo total for lenders). A lender-sponsored realtor joins for $0.
Homeowner HQ is an AI-powered marketing department for agents and lenders — a relationship and revenue engine, not a homeowner database. A homeowner's record routes them back to their own agent; it is never sold and never shown to lenders.
