The specifics

For a Portland business, the choice hinges on cash flow and credit.

• Credit score – Lenders typically require 620–679 (fair) or 740+ (good). According to Crestmont Capital, a 740+ score can pull rates in the 9–12% APR range, while a 620–679 score may see 12–15% APR.
• Down payment – Most purchases need a 15–20% down portion, but some online lenders may offer 0% down for smaller units. Leasing usually starts with lower upfront costs.
• Loan term – Typical 48–60 month terms are common, with 72–84 months adding ~20–30% more total interest (source: Dimension Funding).
• Cash reserve – A cushion of 3–6 months of operating cash is advised (source: Ameris Bank).
• Occupancy & revenue – Desired occupancy >70% and a monthly payment of 8–12% of gross revenue keep debt service comfortable (source: ECMA).

Qualification & edge cases

If your credit is below 620, you may still qualify with a co‑signer or a secured loan, but rates climb higher. Small businesses operating less than 2 years may need to show projected financials or a strong cash flow statement.

For highly seasonal owners, short‑term leases (12–24 months) can align with revenue peaks. If you’re a contractor with multiple sites, consider bundled leases for cost savings. Businesses with >10 units may qualify for volume discounts from specialty banks like Mechanics Cooperative Bank.

Background & how it works

Commercial rooftop HVAC financing follows the same principles as other equipment loans: lenders evaluate credit, cash flow, equipment condition, and collateral. Leasing shifts the risk to the lessor, offering predictable monthly fees and the option to upgrade. Buying keeps the equipment on your balance sheet, giving you Section 179 expensing potential and long‑term ownership benefits (IRS limit: $1,220,000 in 2026). Decision makers often use an affordability calculator to compare depreciation, lease payments, and operating costs.

Bottom line

If you need quick cash flow relief and want upgrade flexibility, leasing is the smarter path. If you’re ready to invest in long‑term asset ownership and can afford a down payment, buying usually saves money over the unit’s life.
