Non-QM lending growth
Maine is a notable Non-QM lending market, with 2,817 Non-QM loans originated in 2025, representing an increase of 18.71% from the previous year. Non-QM lending activity is highly concentrated in the state's most active metropolitan areas, particularly Portland-South Portland, Bangor, and Lewiston-Auburn. Even so, a meaningful share of alternative lending occurs outside these major statistical areas, reflecting the broad geographic expansion of housing across the state. These markets combine unique borrower demographics, including self-employed professionals and real estate investors, driving sustained demand for flexible mortgage products. Leading the charge in origination volume for the state are top-tier lenders such as Rocket Mortgage, Llc, Guild Mortgage Company Llc, and Cmg Mortgage, Inc.. As the housing landscape evolves, Maine continues to demonstrate ongoing reliance on specialized financing solutions beyond traditional agency guidelines.
Polygon Vision estimates that Maine presents a Total Addressable Market (TAM) of approximately 23,720 potential Non-QM borrowers. This opportunity is comprised of 15,285 self-employed households and 8,435 small real estate investors. These segments often struggle with traditional 'box' underwriting due to non-standard income documentation or complex asset structures. Using Polygon CensusVision, we identify the self-employed households via American Community Survey (ACS) data, representing a substantial demand for bank-statement and P&L-based programs. Simultaneously, using Polygon HMDAVision, we identify small real estate investors holding 1 to 4 properties, highlighting a massive need for Debt Service Coverage Ratio (DSCR) lending products. Bridging the gap between this vast combined potential and current origination levels represents a primary growth lever for Non-QM specialists in Maine.
This figure reflects Polygon Research’s estimate of the total addressable Non-QM market in this state. It combines modeled counts of self-employed households with mortgage-relevant income and small real estate investors using ACS microdata processed through CensusVision. How we size the Non-QM market
Polygon Research calculates that Non-QM loans represented 10% of total U.S. mortgage originations in 2025 by loan count and 9.8% by dollar volume, totaling over $232 billion across 697,404 loans. This is based on loan-level HMDA data classified using the ATR/QM regulatory framework. This market size analysis is based on Polygon Research's methodology described in a recent whitepaper.

Non-QM loans include mortgages that do not meet Qualified Mortgage standards due to factors such as alternative income documentation (bank statement loans), debt service coverage ratio underwriting (DSCR loans for investors), interest-only payment structures, pricing above QM thresholds, or sale to private securitizers rather than government-sponsored enterprises. For analytical purposes, Polygon Research also flags business-purpose and DSCR loans separately within the Non-QM category.

Each HMDA loan record from 2018 through 2025 is evaluated against year-specific Ability-to-Repay and Qualified Mortgage standards from 12 CFR §1026.43. Classification is based on observable loan characteristics including pricing thresholds, product features, fee structures, and purchaser type. The full methodology is publicly documented: https://www.polygonresearch.com/whitepapers/unlocking-non-qm-market-intelligence
Most industry estimates rely on securitization data, inferred flags from known Non-QM lender names, samples, or lock activity. Polygon analyzes all funded HMDA loans, including portfolio lending, providing a more complete and transparent view of the Non-QM market.

Yes. For analytical purposes, business-purpose and DSCR loans are incorporated into the Non-QM category and flagged separately, even though ATR/QM rules do not govern business-purpose credit. Learn more in our methodology whitepaper.
Yes. Polygon's Non-QM classification is fully transparent and built on specific, loan-level reason codes (pricing, fees, product features, purchaser type, and more).
