The Commercial Real Estate Due Diligence and Underwriting Playbook

Introduction

A commercial real estate deal can look completely flawless on a spreadsheet and fall apart the moment you step foot in the parking lot. The numbers may align, the cap rate may look attractive, and the listing broker's pro-forma will often promise material upside.

As we consistently reinforce at Price Capital Group, a business or a real estate deal rarely fails because of a bad idea — it fails because of bad fundamentals. As Jason outlines in our breakdown on Why Small Businesses Fail Before They Even Start, success comes down to strict implementation and process. In commercial real estate, that process is your underwriting discipline and due diligence framework.

Phase 1: The Boots on the Ground Physical Inspection

You cannot accurately underwrite a commercial property from behind a desk. A critical part of any real estate due diligence checklist is the physical site visit. Get a drone in the air and walk the property yourself.

In The Route EP 1: Commercial Property Inspection, our team went to evaluate a 34,000-square-foot multi-tenant building. On paper, it presented $367,000 in NOI and an $8.9 million asking price. On-site, the reality diverged from the listing package — drainage problems, a failing parking lot, and a tenant base leaning heavily on below-market rents.

When a defect shows up, stop the line and adjust the offer immediately, or walk away.

Phase 2: Stress-Testing the Financials and Downside Risk

Once the physical real estate is verified, your underwriting must stress-test the income. Consider a 14,000-square-foot industrial distribution center priced at $3.4 million backed by a strong NNN lease with only three years of committed term left. If the tenant leaves, the dark-shell value might drop closer to $60 per square foot — over $800,000 of downside exposure.

Industrial real estate remains near the top of our buy list. Class A distribution centers with 22- to 25-foot ceilings are typically flexible and ready for the next tenant the day the last one moves out.

Phase 3: The Private Lender Hierarchy — Protecting Principal

As outlined in Private Money Lending on The Route: 3 Deals, 3 Answers, every underwriting decision follows three rules: protect the principal, target the yield, and capture appreciation. Principal protection does not move.

Evaluate collateral by its current state, not its potential. A $600,000 loan against a parking lot claimed to be worth $2.2 million once developed is a pass — undeveloped land is weak collateral.

Phase 4: Calculating LTV and Alternative Deal Structures

In our deep dive on Commercial Real Estate Lending: The 800K Burger King Deal, we reviewed a short-term private loan against a freestanding NNN property generating $147,000 annually. At a 7% cap rate, Asset Value = NOI ÷ Cap Rate = $147,000 ÷ 0.07 ≈ $2,100,000.

An $800,000 bridge loan yields LTV = ($800,000 ÷ $2,100,000) × 100 ≈ 38.09%. Sub-40% LTV provides a meaningful equity cushion, and $147,000 of annual income covers debt service roughly two times over.

Build Your Deal System

Due diligence is a system. Watch the scoreboard daily, establish a rigorous inspection process, and only commit to deals where the fundamental leverage makes sense.
