Working with portfolio deals (multiple buildings)
How to handle combined and separate financials for multi-property portfolio underwriting in Archer.
Option 1: Combined financials (one T12 and one rent roll for the whole portfolio)
If the seller provided a single combined rent roll and a single combined T12 covering all buildings:
- Search for one of the property addresses (or create a new property using the portfolio name)
- Edit property attributes to reflect the total unit count across all buildings
- Upload the combined files via Run Underwrite
- Parse as normal — all units from all buildings appear in a single rent roll, all financials in a single T12
This is the simplest path. The output is one model covering the entire portfolio.
Option 2: Separate financials per building
If you have individual rent rolls and T12s for each building:
- Search for each property separately on Archer
- Parse the documents for each property individually (use Parse Document, not Run Underwrite, if you want to parse without generating separate models)
- To get a consolidated view: select all properties and download a consolidated rent roll and T12 that aggregates the data
Each building's data also becomes its own comp, so you get property-level benchmarking within the portfolio.
Tips for portfolio deals
- Always update the unit count in property attributes before parsing — if it says 30 units but the combined rent roll has 240, the comp data will be skewed
- If buildings have overlapping unit numbers (unit 101 in Building A and Building B), add building identifiers before uploading
- You can run the combined underwrite for initial screening, then parse buildings individually for detailed analysis
