How HELOCs Are Structured and Qualified
A Home Equity Line of Credit is a revolving credit line secured by your home, subordinate to your first mortgage. The lender establishes a credit limit based on your combined loan-to-value (CLTV), which is the total of your first mortgage plus the HELOC line divided by the appraised value.
Most lenders allow a maximum CLTV of 80% to 90% for primary residences. If your home is worth $500,000 and you owe $300,000 on your first mortgage, a lender allowing 80% CLTV would offer a HELOC of up to $100,000 ($500,000 x 80% = $400,000, minus the $300,000 existing balance).
HELOCs have two phases: a draw period (typically 10 years) during which you can borrow and repay repeatedly, and a repayment period (typically 10 to 20 years) during which the balance amortizes. During the draw period, most HELOCs require interest-only payments on the outstanding balance. Rates are variable, tied to the Prime Rate or SOFR plus a margin.
Qualifying for a HELOC requires income documentation similar to a purchase loan: income verification, debt-to-income analysis including the new HELOC payment, and a full appraisal or automated valuation. Credit score minimums are typically 620 to 680 depending on the lender and CLTV.
Required Documentation
- ✓Most recent mortgage statement showing current balance and payment
- ✓Two years of tax returns and W-2s (or self-employment documentation)
- ✓30-day paystubs or current income documentation
- ✓Property appraisal or automated valuation (lender orders this)
- ✓Homeowners insurance declarations page
- ✓HOA documentation if applicable
What Most Lenders Get Wrong
- 1.Not explaining how the HELOC payment affects DTI for future transactions. An open HELOC with a zero balance still counts as a monthly obligation based on 1% of the credit limit on many future loan applications.
- 2.Recommending a HELOC without explaining the variable rate risk. A HELOC at Prime + 1% that starts at 8.5% can move to 11% or higher if the Fed raises rates. Borrowers who need predictability are better served by a cash-out refinance into a fixed rate.
- 3.Not disclosing the repayment period payment shock. A borrower who draws $80,000 during the draw period and makes interest-only payments of $550 per month will face fully amortizing payments of $900 or more when the repayment period begins.
- 4.Ignoring the simultaneous close HELOC opportunity on purchases. A borrower who can obtain a HELOC simultaneously with the purchase can use the HELOC to cover part of the down payment, potentially avoiding PMI on the first mortgage.
HELOC vs Cash-Out Refinance: The Rate Math That Drives the Decision
The right choice between a HELOC and a cash-out refinance depends almost entirely on your existing first mortgage rate and how much equity you need to access.
If your current first mortgage rate is lower than today's market rate, refinancing to pull cash out means replacing the entire loan balance at a higher rate. On a $350,000 loan balance, moving from a 3.5% rate to a 7% rate costs roughly $1,200 per month more in interest on that balance. A HELOC on a $100,000 draw at 8.5% costs about $708 per month in interest. The HELOC wins decisively if you are preserving a low first mortgage rate.
If your first mortgage rate is already near current market rates, the comparison is closer. A cash-out refinance into a fixed rate gives you predictability and a single payment. A HELOC gives you revolving access but at a variable rate with payment uncertainty.
For Kern County homeowners who locked in rates in 2020 or 2021 at 3% to 4%, the HELOC is almost always the right tool for accessing equity in the current rate environment. Trading a 3.5% first mortgage for a 7% rate on a large balance to pull $100,000 in cash is nearly always a poor financial outcome.
HELOCs as a Purchase Strategy: The Piggyback Structure
A simultaneous close HELOC, often called a piggyback or 80/10/10 structure, is obtained at the same time as the purchase first mortgage. The borrower takes an 80% first mortgage, a 10% HELOC, and puts 10% down, effectively creating an 80% LTV on the first mortgage without needing to reach 20% total down payment.
The practical benefit: at 80% LTV, the first mortgage avoids private mortgage insurance (PMI). PMI on a 90% LTV loan typically costs 0.5% to 1% of the loan balance annually. On a $400,000 loan, that is $2,000 to $4,000 per year. A HELOC interest-only payment on a $40,000 line at 8.5% is about $283 per month, or $3,396 annually, which is competitive with or better than the PMI cost depending on the specific numbers.
The secondary benefit: the borrower retains revolving access to the HELOC after the purchase, which can be used for renovations, emergencies, or future investment.
Not all lenders offer simultaneous HELOC closings on purchases, and those that do have specific timing and documentation requirements. The HELOC lender must agree to be in second lien position behind the first mortgage lender. This requires coordination, but it is a strategy I use regularly for purchase clients who want to minimize their down payment while avoiding PMI.
The number of homeowners in Bakersfield who refinanced in 2020 or 2021 and locked in rates below 4% is significant. Almost none of those borrowers should be doing a cash-out refinance today to access equity. A HELOC preserves the first mortgage rate while giving access to equity. The only time I recommend a cash-out refi instead is when the borrower needs a large fixed payment and cannot tolerate the variable rate risk of a HELOC.
