Question 1

What does the Lowtility Savings Calculator do?

Accepted Answer

It estimates how much you could save each month by financing solar panels and paying off high-interest debt through a refinance or HELOC. You enter your mortgage details, debts, credit score, and solar system cost. The calculator compares two options — keeping your current mortgage and adding a HELOC, or refinancing into a single new loan — and shows the recommended path.

Question 2

How does the calculator compare a HELOC vs. a refinance for solar?

Accepted Answer

A HELOC keeps your existing mortgage rate intact and adds a second lien for solar and debt payoff with interest-only payments — but only available with a 660+ credit score and combined loan-to-value under 90%. A Lowtility Refi rolls your mortgage, solar costs, and debts into one new 30-year loan with a fixed rate around 6.5% — works for credit scores 540+, but resets your mortgage. The calculator runs both options and recommends whichever produces the lower total monthly outgo.

Question 3

Do I qualify for a HELOC for solar?

Accepted Answer

HELOC eligibility through Lowtility requires a credit score of 660 or higher, no mortgage payments more than 30 days late in the past 12 months, a combined loan-to-value (first mortgage + HELOC) at or below 90%, and a minimum loan size of $30,000. The calculator flags eligibility automatically based on your inputs.

Question 4

What credit score do I need to refinance through Lowtility?

Accepted Answer

A Lowtility Refi requires a credit score of 540 or higher, no mortgage payments more than 30 days late in the past 12 months, and a minimum loan size of $75,000. Loan-to-value above 85% will trigger a flag for additional review but is not automatically disqualifying.

Question 5

Are the calculator's savings numbers a loan offer?

Accepted Answer

No. The calculator returns estimates only based on the figures you enter and current program assumptions. It does not constitute a commitment to lend, a loan offer, or financial advice. A final commitment requires underwriting acceptance, a credit pull, an appraisal, and review of income documentation.

Question 6

Will using the Lowtility Savings Calculator affect my credit score?

Accepted Answer

No. The calculator runs on the estimated credit score you enter — there is no credit pull. A formal credit check happens only if you choose to apply for a loan.

Question 7

What if my credit score is below 660?

Accepted Answer

If your credit score is between 540 and 660, a HELOC won't be available, but a Lowtility Refi may still work. Below 540, neither option is available through this program. The calculator will tell you which paths are open based on your inputs and recommend talking with a Lowtility specialist about alternative solutions.

Question 8

Can I roll high-interest debt into my mortgage to pay it off?

Accepted Answer

Yes. Both a Lowtility Refi and a HELOC can be used to pay off credit cards, car loans, and other consumer debt as part of the financing. The calculator includes a section where you list each debt and choose which ones to pay off, then shows your monthly outgo with those debts cleared.
