How to Integrate Your Own Excel Underwriting Model

Updated over a week ago

Many teams prefer to continue using their own Excel-based underwriting models, especially when they’ve been refined over years of deal-making. IntellCRE’s Enterprise Model Integration allows you to keep that workflow—while seamlessly syncing your underwriting data into the platform for analysis, reporting, and marketing.

With this feature, you upload your full Excel model directly into a new deal, and IntellCRE automatically extracts and maps your financials, assumptions, rent roll, and property data into the platform. This eliminates double entry and ensures your existing modeling workflow stays intact.


What Is the Model Integration Feature?

Model Integration is an Enterprise feature that connects your internal Excel underwriting model to IntellCRE. Once configured for your team, it enables:

  • Automatic extraction of data from your Excel model

  • Mapping of all key data points into IntellCRE (rent roll, assumptions, expenses, valuation, and more)

  • Support for multi-tab, complex models (e.g., multifamily, self-storage, industrial, retail, and other custom models)

  • A frictionless workflow where you underwrite in Excel and generate all marketing materials in IntellCRE seconds after

Once your model is integrated, every time you create a new deal, you can simply upload your Excel file and the system will map your entire underwriting into the platform within seconds.


Step 1: Upload Your Excel Model

To begin the integrated workflow, upload your in-house underwriting Excel model during deal creation:

  1. Start a new deal Analysis in IntellCRE

  2. Choose the Property Type

  3. Drag and drop your full underwriting Excel file into the Complete Excel Model box.

  4. Click Create Property and Analysis

  5. Within a few seconds, the key financial and property data in your model are mapped into the platform.


Step 2: How the Platform Maps Your Model

Once uploaded, the platform auto-populates the analysis form and the right-hand sidebar with data from your file. This includes:

Unit Mix & Rent Roll

For asset types like self-storage (as shown in the example), the system imports all unit-mix details across multiple tabs:

  • Climate-controlled units

  • Non-climate units

  • Ground and non-ground units

  • Drive-up units

  • Parking and other unit types

It maps dimensions, counts, vacancy, current rents, market rents, square footage, and more.

Income

Pulled from your assumptions tab:

  • Rent growth

  • Vacancy

  • Rent loss

Other Income

Extracted from your Proforma tab:

  • Per-unit or per-square-foot income

  • Current vs. proforma

  • Any custom income line items

Expenses

Mapped directly from your proforma’s expense section:

  • Operating expenses

  • Taxes and tax-resets

  • Expense growth rates

  • Custom expense categories

Valuation & Financing

From your price proposal tab:

  • Property value

  • Price assumptions

  • Sensitivity-based valuation inputs

  • (If included) sales comps or acquisition assumptions

Every data point flows into the correct field in IntellCRE—no manual entry required.


Step 3: Create the Property Analysis

Once the data is mapped:

  1. Click Create Analysis.

  2. IntellCRE generates your full financial analysis, including cash flows, performance summary, and underwriting outputs.

  3. You can now proceed to comps or to generating marketing materials.

Your Excel model becomes the foundation for your deal analysis inside the platform.


Step 4: Use Your Underwriting for Marketing Materials

After your analysis is built, you can immediately create:

All sections for your marketing presentations—financials, rent roll, assumptions, charts—pull directly from the data extracted from your Excel model. No additional formatting or re-entry is needed.
