What is the difference between a HELOC and a closed-end second mortgage?
A HELOC is a revolving line of credit — borrower can draw, repay, and re-draw during the 10-year draw period, with interest-only payments during the draw period and amortizing P&I payments during the 20-year repayment period. The rate is variable, indexed to Prime. A closed-end second is a traditional installment loan — fully funded at closing, fixed rate, fixed P&I payments over a fixed term (10–30 years), no draws after closing. HELOC is for flexible/recurring needs; closed-end second is for one-time defined needs.
Why would I take a second mortgage instead of a cash-out refinance?
Because you keep your existing first-lien rate. If you closed your first mortgage when rates were 3%, refinancing to pull cash means giving up that 3% in exchange for today's rate on the entire balance. A second mortgage leaves the 3% first untouched and only adds today's rate on the new balance. On a $500K first at 3% with $100K of new debt at 8%, the blended rate is 3.83% — versus refinancing the entire $600K at 7% (single-loan). Massive difference in lifetime interest.
What is a piggyback second mortgage?
A second mortgage closed simultaneously with the purchase first mortgage to avoid either jumbo pricing or PMI. The most common structures are 80/10/10 (80% first, 10% second, 10% down) and 80/15/5 (80% first, 15% second, 5% down). Either way, the first lien stays at 80% LTV — which keeps it at conforming pricing if the loan amount is otherwise jumbo, and which avoids the PMI requirement that kicks in above 80% on conventional.
How is a HELOC payment calculated?
During the 10-year draw period: interest-only on the drawn balance at the variable rate (Prime + margin). $50,000 drawn at 8.5% = $354/month. During the 20-year repayment period: P&I amortizing the drawn balance at the then-prevailing variable rate. The same $50,000 at 8.5% over 20 years = $434/month. The payment shock at draw-period-end can be material — borrowers should model both phases before drawing aggressively in the first 10 years.
Can I deduct HELOC interest on my taxes?
Federal: HELOC interest is deductible only if the proceeds are used to "buy, build, or substantially improve" the home securing the loan (per the 2017 Tax Cuts and Jobs Act, in effect through 2025 [VERIFY current law]). Interest on HELOC funds used for non-housing purposes (debt consolidation, tuition, business) is not federally deductible for tax years currently in effect. State treatment varies. Check with your CPA — we don't give tax advice.
How fast can a HELOC close?
Typically 2–4 weeks from application — much faster than a first-mortgage refinance (4–6 weeks). No appraisal is required on many HELOC programs (lender uses an automated valuation model or a previous appraisal); income docs are streamlined; and the rescission period is 3 business days vs. nothing on a purchase first. Bridge HELOCs can close in 7–14 days when the use-case is time-sensitive.
Can I get a HELOC on an investment property?
Yes, on specialty programs. Most retail banks don't do investment-property HELOCs — we have wholesale placement that does. Tighter LTV (80% max), higher rates than primary-residence HELOC, but lets a landlord pull equity from a stabilized rental without a full DSCR cash-out refinance. Closes in personal name or LLC.
What happens if I sell the home with a HELOC on it?
The HELOC must be paid off at closing (same as the first mortgage). Title cannot transfer with an outstanding HELOC because it's a lien on the property. The closing-cost statement (CD) shows the HELOC payoff coming out of sale proceeds. After payoff, the line is closed — the borrower cannot continue to draw against the line on the new property.
