The Tenantvein Platform
From rent roll ingestion to LP-ready deal brief in under 90 seconds. Tenantvein replaces days of manual data assembly with a single automated workflow built for mid-market acquisition teams.
The Problem
Acquisitions analysts and asset managers at mid-market CRE investment firms and regional REITs face the same problem every time a new deal enters the pipeline: the underwriting process requires stitching together rent rolls, comps data, macro market signals, and tenant credit profiles from a dozen separate data sources.
The process is manual, error-prone, and slow at exactly the moment speed matters most. Downloading a rent roll PDF and reformatting it by hand takes hours. Pulling comparable lease transactions from CoStar and broker emails takes a day or more. Cross-referencing each tenant against credit data requires Bloomberg access or laborious manual research. By the time the model is ready for IC review, the market has moved — or a faster-moving competitor has already signed.
This is not an analytical failure. It is a data infrastructure failure. The judgment to evaluate a deal exists in-house. What's missing is a system that assembles the data fast enough for that judgment to matter.

How It Works
Three inputs. One automated workflow. A complete underwriting package delivered in under 90 seconds.
Step 01 — Input
Submit a PDF, Excel, or CSV rent roll in any format — Tenantvein handles inconsistent layouts, scanned images, and multi-sheet workbooks. Add the property address and select the asset class (office, multifamily, industrial, retail, or mixed-use). That is all the input required to start.
Step 02 — Processing
Tenantvein's AI normalizes the rent roll into a structured tenant-by-tenant ledger, cross-references each tenant against credit bureau signals and sector revenue benchmarks, retrieves comparable lease transactions from the proprietary database of over 2 million CRE leases, applies market vacancy and rent growth forecasts for the specific submarket, and generates a risk-weighted underwriting output with scenario analysis — all in under 90 seconds.
Step 03 — Output
Receive a downloadable Excel underwriting model with pre-built DCF, NOI bridge, and sensitivity tables; inline AI commentary identifying rent roll risks and upside; a market comps summary with sourced transaction data; and a one-page deal brief formatted for LP review and IC approval. Every output is ready to defend in an investment committee meeting.
Platform Features
From the moment you upload a rent roll to the moment you hand an LP-ready brief to your investment committee — Tenantvein handles the data work so your analysts can focus on the judgment calls that actually require their expertise.
AI Rent Roll Normalization
Convert any rent roll format into a clean structured ledger in seconds
Upload a PDF, scanned image, or Excel rent roll in any format and Tenantvein's extraction engine automatically identifies tenant names, suite numbers, lease start and end dates, base rent, escalations, and CAM charges. The system flags anomalies — below-market tenants, lease expiries clustering in the same window, and missing rent steps — so analysts catch risk before it compounds in the model.
Tenant Credit Intelligence
Assess tenant credit quality without a Bloomberg terminal
For each tenant in the rent roll, Tenantvein surfaces sector health data, D&B credit ratings, recent lease activity, and parent-company financials where available. Analysts get a credit tier score (A through D) per tenant plus a portfolio-weighted credit quality index — replacing the hours typically spent on manual tenant research with a single structured view.
Submarket Comps Engine
Pull verified lease comps for 50 major US metros in real time
Tenantvein's proprietary comps database aggregates over 2 million verified CRE lease transactions updated quarterly. Filter by asset class, submarket, building class, and lease size to generate a comps package that directly populates the underwriting model with market-supported rent assumptions — eliminating the back-and-forth with CoStar brokers or manual comp sheets.
Scenario Modeling
Run base, bear, and bull cases instantly without rebuilding the model
Once the baseline underwriting is generated, analysts can adjust vacancy assumptions, market rent growth trajectories, cap rate ranges, and exit timing with a single slider interface. Every scenario variant updates the DCF, IRR, and equity multiple outputs simultaneously, making sensitivity analysis fast enough to run live during LP calls or IC presentations.
Portfolio Dashboard
Track asset performance and lease expirations across your entire hold period
The portfolio dashboard aggregates all active assets into a single view showing NOI performance vs. underwriting, upcoming lease expiries, tenant credit changes, and submarket rent trends for each property. Asset managers get a weekly digest of the highest-risk events across their portfolio, so proactive leasing and capital planning decisions get made before problems surface in cash flow.
One-Page Deal Brief
Auto-generate an LP-ready deal summary from every underwriting run
At the end of every underwriting session, Tenantvein generates a structured one-page deal brief covering asset description, tenancy quality, market positioning, key assumptions, risk factors, and return profile. The brief is formatted for LP review and IC approval — reducing the time from underwriting completion to investment memo by two to three days.
Integrations
Who It's For
Tenantvein is for
Acquisitions directors and senior analysts at mid-market CRE investment firms, regional REITs, and family offices actively acquiring office, industrial, and mixed-use properties in major US markets.
Firms managing $100 million to $2 billion in AUM with active acquisition pipelines of 20 to 100 deals per year — teams large enough to have a real pipeline but lean enough that every analyst hour matters.
Deal teams that currently spend more than a day per deal assembling rent rolls, hunting comps, and reformatting data before the actual analysis can begin. If your analysts are doing data entry instead of analysis, Tenantvein was built for you.
Tenantvein is not for
Residential real estate brokers, individual flippers, or agents working below the commercial threshold — Tenantvein is purpose-built for commercial property underwriting, not residential transactions.
Institutional mega-REITs with fully-staffed in-house research teams, proprietary data infrastructure, and dedicated data science departments. If you already have 30 analysts and a custom data pipeline, Tenantvein adds less marginal value than it would for a lean team.
Firms that do fewer than 20 deals per year opportunistically — the ROI on a structured underwriting platform scales with pipeline volume. At very low volumes, the existing manual process may be sufficient.
