Commercial Underwriter Training

Underwriting is not spreadsheet operation. The spreadsheet is the last step. The work begins with reconstructing net operating income from primary evidence (a rent roll, a trailing twelve-month operating statement, tax returns, bank deposits) and reconciling those sources against each other rather than accepting the sponsor's stabilized pro forma at face value. Most of what separates a competent underwriter from a junior analyst happens here, in the normalization: adding back non-recurring items, marking below-market rents to market only where lease expiry actually permits it, underwriting a management fee whether or not the sponsor self-manages, and sizing replacement reserves the borrower left out.

From a defensible NOI, loan sizing becomes an exercise in finding the binding constraint. A deal is not sized at the maximum LTV; it is sized at whichever of LTV, debt service coverage ratio, debt yield, or loan-to-cost produces the smallest proceeds. This program teaches the underwriting models that run those four tests simultaneously, including the circularity that arises when a DSCR-constrained loan amount feeds the debt service it is being tested against, and the amortization and debt-constant mechanics that determine how a rate or term change moves proceeds.

Credit judgment is then layered on top of the arithmetic. Sensitivity and stress testing establish how far occupancy, rents, exit cap rate, or the refinance rate can move before coverage breaks: the break-even analysis that tells a committee where the real risk sits. Valuation is treated across all three approaches, because an underwriter who cannot interrogate an appraisal's cap rate selection, adjustment grid, or terminal assumptions is dependent on it. Alongside this runs the risk taxonomy (sponsor capacity, tenant and lease rollover concentration, refinance risk, deferred maintenance, environmental and title findings) and the loan structure that responds to it: recourse and non-recourse carve-out guaranties, reserves and escrows, covenants, and cash management triggers.

The program closes the loop with full deal lifecycle simulation. Worked case studies and scored simulations put you inside files where the numbers do not reconcile, a tenant concentration is disguised, or a structure has to be renegotiated: the situations where underwriting judgment is actually tested, rather than confirmed.
