All Financing Options Compared
Manufacturer financing (Generac PowerPay, Kohler)
Pros
Convenient, applied at point of sale. Promotional 0% periods available spring and fall.
Cons
Rates jump after promo period. Deferred interest: if not paid in full during promo, interest is charged retroactively.
HELOC (Home Equity Line of Credit)
Pros
Lowest ongoing rate for homeowners with equity. Interest may be tax-deductible. Flexible draw schedule.
Cons
Variable rate means payments can increase. Uses your home as collateral. Requires equity and good credit.
Home equity loan
Pros
Fixed rate and fixed payment. Predictable. Lower rate than personal loans.
Cons
Closing costs ($500-$2,000). Slower to fund than personal loans. Home is collateral.
Unsecured personal loan
Pros
Fast funding (1-3 days). No collateral required. Simple application.
Cons
Highest rate option. Requires good credit for best rates. Shorter terms mean higher monthly payments.
Utility on-bill financing
Pros
Very low rates. Payments added to monthly utility bill. Some utilities subsidize generator installation.
Cons
Limited availability. Only in select markets with grid reliability programs. May have income or home value requirements.
PACE financing
Pros
Repaid through property tax. Stays with the property if you sell. Long terms mean low monthly payments.
Cons
Only available in FL, CA, and select states. Creates a tax lien on the property. Some mortgage lenders have restrictions.
0% Interest Promotions
Generac and Kohler periodically offer 0% APR financing for 12-18 months through their dealer networks. These promotions typically run in spring (March-May) and fall (September-October) to stimulate off-peak sales. The catch: these are usually deferred interest programs. If you do not pay the full balance within the promotional period, interest is charged retroactively from the purchase date at rates of 18-26%. To benefit from 0% financing, you must be able to pay the full amount within the promo period. On a $12,000 generator at 18 months, that means $667/month. If that is not feasible, a HELOC or home equity loan at 6-9% is a better option with lower risk.
