Origination and Underwriting Process
The portfolio loan process begins with the borrower approaching a portfolio lender, typically a community bank, credit union, or regional bank with an active commercial or investor lending program. Unlike conventional loans, which are processed through standardized automated underwriting systems (DU or LPA), portfolio loans are underwritten manually by the lender’s credit team. The underwriter evaluates the borrower’s overall financial picture, including personal and business financial statements, tax returns (if applicable), a schedule of real estate owned, global cash flow analysis, and the specifics of the subject property.
The global cash flow analysis is a distinguishing feature of portfolio underwriting. Rather than applying rigid DTI ratio limits, portfolio lenders often calculate the borrower’s total income from all sources (employment, rental income, business income, investment income) against total obligations (all mortgage payments, business debt, personal debt, living expenses). This holistic view can benefit investors whose conventional DTI is too high due to multiple mortgages but whose overall cash flow is strong when rental income from all properties is properly accounted for.
For entity borrowers (LLC, LP, trust), the lender reviews the entity’s operating agreement, articles of organization, and authorized signers in addition to the personal financial profile of the guarantor(s). The lender assesses whether the entity is properly structured and whether the guarantor has sufficient personal net worth and liquidity to support the guarantee.
Loan Structuring and Terms
Portfolio loan terms are more varied than conventional products. Common structures include 30-year fixed rate (less common and more expensive), 5/1 or 7/1 adjustable rate (fixed for an initial period, then adjusting annually based on an index plus margin), 10-year or 15-year fixed with a balloon (the rate is fixed, but the loan must be paid off or refinanced at the end of the term), and 20 or 25-year full amortization (no balloon, but a shorter payoff period than 30 years).
The lender and borrower negotiate the specific terms based on the lender’s product offerings and the borrower’s preferences. Interest rates are typically set based on a spread over a benchmark rate such as the 5-year or 10-year Treasury yield, the prime rate, or the lender’s internal cost of funds. The spread reflects the lender’s assessment of the borrower’s risk, the property’s risk, and the lender’s target return on the loan.
Loan-to-value ratios on portfolio products typically range from 65% to 80%, depending on the property type, the borrower’s strength, and whether the transaction is a purchase or refinance. LTV limits tend to be more conservative than conventional guidelines for riskier scenarios (entity borrowers, non-standard properties) and comparable for straightforward investment purchases with strong borrowers.
Ongoing Servicing and Renewal
Because the portfolio lender retains the loan, servicing is handled internally rather than transferred to a third-party servicer. This can be advantageous for borrowers: the same institution that approved the loan manages it ongoing, and any issues (payment modifications, escrow disputes, payoff requests) are handled by a relationship contact rather than a faceless servicing center.
For loans with balloon provisions, the renewal process is a critical ongoing obligation. As the balloon date approaches, the borrower must either pay off the loan in full, refinance with a different lender, or negotiate a renewal with the existing lender. Most portfolio lenders are willing to renew balloon loans for borrowers who have maintained good payment history and adequate property condition, but the renewal is at the lender’s discretion and the terms (rate, amortization, new balloon period) are renegotiated at renewal. This creates uncertainty that borrowers must plan for.
