Should Your Borrower Put More Money Down — or Reduce Their Energy Bill?
Sacramento Solar Guide helps mortgage professionals compare the energy-cost side of homeownership so borrowers can think beyond principal, interest, taxes, insurance, and HOA.
Borrowers experience total monthly cost — not just the mortgage payment.
PITI + HOA is only part of the story. Utility bills, EV charging, pool equipment, summer AC usage, and backup power concerns can quietly reshape what a borrower can actually afford month to month.
When a borrower has extra cash, ask a better question.
The default question is: “How much more should they put down?”
A better question may be: “Where will this money create the greatest monthly benefit?”
Six places that extra cash can go.
Larger down payment
Lower loan balance and monthly principal & interest.
Rate buydown
Use cash to reduce the interest rate and monthly payment.
Reserves
Keep cash on hand for safety, repairs, and life events.
Solar + batteries
Reduce utility cost and add backup power resilience.
Battery-only option
Cut peak charges and add backup — even without panels.
Home improvements
Address near-term needs that affect comfort or value.
A high-usage home with extra cash on the table.
A borrower buying a high-usage home may be concerned about a $500–$700+ PG&E bill and has extra cash beyond the required down payment. It may be worth comparing whether extra cash toward the mortgage — or toward solar/batteries — creates a better monthly cost-of-ownership outcome for that specific borrower.
