Why Financing Bias Creeps Into a Pipeline
Lead vendors that filter or score for "loan-qualified" homeowners are optimizing for the one financing path their scoring model can verify cheaply through a credit check. That filter is convenient for the vendor. It is also quietly excluding a growing share of the actual 2026 buyer pool, now that TPO is the majority financing path for many reps and a homeowner's credit profile has little to do with whether a lease or PPA deal is a fit for them.
The Math That Makes This Urgent, Not a Preference
Reps reporting more than half their 2025 book was TPO stood at 44%, and that is projected to hit 65% in 2026. Reps selling zero TPO dropped from 9% to 1% over the same period. A pipeline still built around loan-qualified filtering in 2026 is chasing a shrinking share of the market it was designed for a year or two ago.

Qualification criteria center on real intent and decision-making authority: is this the actual homeowner, do they have a genuine reason to be exploring solar now, is the property in the service area. None of those questions requires knowing in advance whether the homeowner will end up paying cash, financing a loan, or signing a lease. The appointment converts whichever way the homeowner lands, because the vendor was never filtering for one outcome in the first place.
The Cost of Getting This Wrong
If a booked-appointment vendor is quietly optimizing for loan-qualified homeowners only, a rep walks into a growing share of appointments skewed toward a financing path that is shrinking relative to TPO. Every appointment booked against the wrong assumption is a wasted slot in a year where each one costs more to generate. Ask any vendor directly, before you sign, whether their qualification process screens or filters by financing type at all.
Building or Buying a Pipeline That Does Not Play Favorites
Define qualification criteria around intent and decision authority, not around a specific financing outcome. If buying appointments, get a direct answer from the vendor about how they qualify homeowners before you commit a dollar. VA Horizon's own solar appointment model is built this way by design: financing-agnostic, converting whether the homeowner lands on cash, loan, or third-party-ownership financing, at a published $300 one-time setup and $249 per booked appointment.
What this means for you
- TPO now makes up a majority of many reps' books, projected to hit 65% in 2026 up from 44% in 2025, and a pipeline that quietly filters for loan-qualified-only homeowners is optimizing against that trend.
- Financing-agnostic qualification confirms intent and decision-making authority, not a specific payment outcome, so the appointment is worth booking regardless of how the homeowner ultimately pays.
- Ask any appointment or lead vendor directly whether they screen or filter by financing path before you buy from them. A vendor who cannot answer clearly is telling you something.
