Home Equity & Debt

Are my HELOC and solar payments actually reducing what I owe?

Maybe not. If a home equity line of credit or solar financing is in an interest-only period, your payments may be covering interest without reducing the balance. Many Arizona homeowners don't realize this until they try to refinance — or try to sell — and discover how much they still owe.

A real example from my desk

A homeowner in Paulden, Arizona contacted me wanting a lower monthly payment. Their combined monthly obligations were approximately $4,358 across a first mortgage, an interest-only HELOC and solar panel payments.

We consolidated everything into a single FHA mortgage. The new FHA loan used cash-out equity up to 80% of the home's value, the credit score requirement for their program was a minimum 660 FICO, and because it was an amortizing mortgage, every payment reduced what they owed instead of just covering interest. Their monthly payment dropped by several hundred dollars — and the loan actually pays itself down.

Three questions to ask about your current loans

  • Am I in an interest-only period on my HELOC?
  • Is my solar loan or lease balance shrinking each month, or just collecting interest?
  • If I sold my home today, would the payoff numbers surprise me?

What a refinance can and cannot do

Consolidating an interest-only HELOC or solar financing into one amortizing mortgage can simplify payments and start reducing principal — but it moves that debt into a loan secured by your home, and loan-to-value limits, credit requirements and program guidelines all apply. Every situation is different, so it's worth reviewing the full picture before deciding.

Related Questions

What does an interest-only HELOC payment mean?

During an interest-only period, your payments cover interest but do not reduce the principal balance. The balance only starts shrinking once the loan enters its repayment period — or if you pay extra toward principal.

Can I refinance if I have solar panels?

Often, yes. Solar loans, leases or power purchase agreements affect how a refinance is structured, and whether the solar balance is paid off, assumed or left in place depends on the arrangement and the loan program. It's one of the first things I review.
