Speed in CRE acquisitions isn't just a competitive advantage — it's table stakes. We've spent the past year working with mid-market deal teams across the US and tracking how long underwriting actually takes, from rent roll receipt to IC-ready model. The numbers are both familiar and uncomfortable.

The Baseline: Where Most Teams Start

Our data shows the median deal underwriting cycle at mid-market CRE firms runs 3.8 analyst-days from initial rent roll receipt to a completed underwriting model ready for investment committee review. That's not 3.8 days of continuous work — it's elapsed calendar time, accounting for the back-and-forth with brokers on missing lease abstracts, the manual comp research, and the two rounds of model QA before a senior associate feels comfortable sending it up the chain.

The fastest teams we've observed — typically firms that have already invested in structured data workflows — complete the same process in under 18 hours. The slowest are routinely at 7-plus days, especially when the asset is a mixed-use property with stacked leases, or when the rent roll arrives as a scanned PDF with inconsistent formatting. That 7-day outlier is where deals die. A competing bidder who closes diligence in 2 days while you're still normalizing the rent roll on day 4 has already submitted an LOI.

The breakdown we see most consistently: about 38% of analyst time goes to data gathering and normalization — extracting tenant information, standardizing lease terms, filling in missing fields. Another 28% goes to comp research. The remaining 34% is the actual modeling and scenario analysis, which is the part where human judgment genuinely matters. That ratio is inverted from what it should be.

Where Time Goes: The Three Friction Points

In our experience, the underwriting delay problem concentrates in three places almost universally.

Rent roll normalization. The rent roll arrives in whatever format the seller's property management system exports — or doesn't export. We've seen everything from structured Yardi extracts to Excel files with 14 merged cells per row to handwritten-looking PDFs that appear to have been scanned at a slight angle. Every analyst has their own method for getting that into a usable ledger, which means there's no reproducibility and no speed floor. A junior analyst might spend 6 hours on a 40-tenant rent roll. A senior analyst does it in 2. Neither number is acceptable at deal velocity.

Comparable lease research. Comp work is still largely manual at most firms below $2B AUM. CoStar is the default tool, but pulling comps for a specific submarket, filtering by building class, lease size, and signing date, then cross-referencing against broker intel — that's a 4-6 hour task on a typical office or industrial deal. And the output is often a mix of verified and unverified transactions, which introduces its own set of problems downstream in the model.

Model QA and reconciliation. Even after the data is in, the model requires a QC pass — checking that NOI flows match the rent roll, that vacancy assumptions are defensible, that the DSCR at the stated cap rate makes sense. When the input data was assembled manually, errors surface at this stage and kick the process back to the beginning. We've seen deals where the analyst had to rerun the full normalization process twice because of data entry errors caught in QA.

What the Fastest Firms Do Differently

The deal teams that close underwriting in under 24 hours aren't necessarily larger or better-resourced. In many cases, they're smaller — 2 to 4 analysts covering an active pipeline of 30-50 deals per year. What they've done is standardize the assembly layer of the process so that human judgment kicks in at the right moment, not before.

"The analysis itself doesn't take that long. What takes forever is getting the data into a shape where you can actually analyze it." — comment we hear repeatedly from acquisitions directors across office and industrial portfolios in the Northeast and Sun Belt.

Specifically, fast teams share several practices. They have a defined rent roll intake format — either they receive data directly from property management systems via structured export, or they use a normalization tool that converts inbound formats automatically. They maintain a live comps database specific to their target markets, updated quarterly, instead of rebuilding their comp set from scratch on every deal. And they run model QA against a rules-based checklist rather than relying on a senior analyst's memory of what to check.

None of these practices require a large technology budget. But they do require a deliberate decision to treat data assembly as infrastructure rather than analyst busywork.

The Deal Loss Calculation

The real cost of slow underwriting isn't the analyst hours — it's the deals you don't win. We've seen this quantified informally by several deal teams who tracked their pipeline over 12 months. The pattern: roughly 1 in 5 deals where they submitted an offer in the first 72 hours of a deal process, they won or were shortlisted. For deals where their underwriting took longer than 5 days, that rate dropped to about 1 in 9. The competition wasn't necessarily smarter; they were just faster.

At deal economics of $5M-$50M equity checks, even a single incremental closing per year more than justifies any investment in underwriting infrastructure. The math isn't complicated, but it requires teams to stop treating underwriting speed as a nice-to-have and start treating it as a revenue driver.

There's also a secondary effect on deal selection. When your underwriting process is slow, you become more selective about which deals you'll pursue because of the cost of each diligence cycle. Teams with fast underwriting can evaluate more deals, maintain optionality longer, and make better-informed decisions about what to bid on and at what price. That portfolio selection advantage compounds over time.

What 2025 Benchmark Numbers Show

Across deal teams in our early network, we've tracked underwriting cycle times by asset class and deal size. Office deals take the longest on average — 4.2 analyst-days at the median — largely because of tenant-by-tenant credit research and the complexity of multi-floor leases with TI/LC amortization and various CAM cap structures. Industrial deals are faster at 2.9 days median, though they've gotten more complex as lease structures compress to shorter terms with more frequent renewal options. Multifamily sits in the middle at 3.3 days, with most of the delay concentrated in comp research for rent-stabilized or mixed-regulation portfolios where market-rate assumptions need additional support.

These benchmarks matter because they give deal teams a realistic anchor for what's achievable. A 4.2-day median for office underwriting doesn't mean 4.2 days is the floor — it means most teams are still working at 2018-era speeds despite having substantially better data available to them. The teams running at sub-2-day cycles on office deals are outliers today. In two years, they'll be the baseline.

At Tenantvein, we built our platform specifically around compressing those three friction points — normalization, comp retrieval, and model population — so that deal teams can spend their time on judgment rather than assembly. The output isn't just a faster underwriting; it's a model whose inputs are traceable, whose comp support is documented, and whose NOI math has been checked against the underlying data automatically. That auditability matters at IC, at LP reporting time, and when a deal goes sideways and you need to understand why your underwriting missed the mark.

Getting Started: A Practical Benchmark for Your Team

If you want to assess where your team stands, start with one measure: track elapsed time from rent roll receipt to completed underwriting model on your next five deals. Don't filter for "clean" deals — include the messy ones. Average that number. If you're above 3 days, you have a structural inefficiency worth addressing. If you're above 5 days, it's urgent.

Then break down that elapsed time into the three friction categories above. Usually one of them accounts for more than 50% of the total. That's where to start.

The goal isn't to eliminate analyst judgment — it's to make sure your analysts spend their judgment on the things that actually require it. Cap rate selection, market rent assumptions, tenant credit assessment, exit timing. Those decisions are genuinely complex. Copying tenant names from a PDF into a spreadsheet is not. The distinction seems obvious when you state it plainly, but most deal teams are still allocating their highest-value people to the second type of task far too often.

Speed benchmarks exist to make that gap visible. The firms that take them seriously are the ones closing deals their competitors missed.
