Every lender doing more than a handful of deals a year eventually runs this calculation: hire an underwriter, or send the files out? The instinct is that in-house must be cheaper — you are paying a salary instead of per-deal fees. The instinct is usually wrong until volume is high and steady. Here is the actual math.
A competent CRE underwriter or credit analyst runs $90K–$150K in base salary depending on market. Fully loaded — payroll taxes, benefits, software seats, data subscriptions, workspace, management overhead — the real number lands between $120K and $200K a year. Add the one-time costs: recruiting fees or the originator hours spent interviewing, and a ramp period of three to six months before output is committee-ready without heavy review. If the hire does not work out, you pay the cycle twice.
The fixed cost is only half the issue. The deeper problem is utilization. Deal flow in most shops is lumpy — a $150K underwriter carrying two files in a slow month costs you the same as one carrying ten in a busy month. In the slow month you are paying roughly $6,000 per file in loaded cost; in the busy month your underwriter is the bottleneck and files sit anyway. A fixed resource against variable volume guarantees you are wrong in one direction or the other most of the time.
Outsourced underwriting prices per file, typically scaled to complexity — a stabilized multifamily refi is not a construction loan with a three-entity guarantor structure. The structural advantage is that cost attaches to revenue: every underwriting dollar you spend has a live deal, and usually origination income, on the other side of it. Slow months cost nothing. Volume spikes are covered without anyone working weekends. And the deliverable arrives with the underlying models, so your credit team can audit rather than rebuild.
Take a loaded cost of $150K and a realistic capacity of 12–15 files a month for one underwriter. At full utilization that is roughly $800–$1,000 per file — but almost nobody runs at full utilization year-round. At a more typical 6–8 files a month, the true in-house cost is $1,500–$2,000 per file, before recruiting and ramp. Compare that to per-file outsourced pricing and the crossover point becomes clear: below roughly 10–15 consistent files a month, per-file wins on cost alone; above it, in-house starts to compete — provided the volume is genuinely steady. Run your own trailing-twelve numbers: total loaded cost divided by files actually underwritten. Most shops are surprised by the answer.
Two factors do not show up in the per-file math. Independence: a committee reading an in-house underwrite knows the analyst reports to the same P&L as the originator. A third-party read is structurally free of that pressure, and for some credit cultures that alone justifies the model. Seniority: $150K buys you one mid-level analyst; per-file pricing from the right firm buys principal-level review on every file — someone who has closed transactions, not just modeled them. The question is not only what underwriting costs, but what quality of judgment each dollar buys.
Under 10 files a month, or volume that swings: outsource per-file. Steady recurring volume but not enough to keep a hire busy: a dedicated-capacity retainer — defined files per month, consistent clock. Committee wants your letterhead and your formats: a white-label underwriting desk. Fifteen-plus steady files a month with growth ahead: hire — and consider keeping an outsourced bench for overflow so the hire is never the bottleneck.
