There are a couple of data sources that are best used for commercial properties only. Here's how you would create a commercial property report using AUTOPROP.
Firstly, search for a property and create a Property Report:
Once you've clicked Property Report report, click "Adjust Report Contents" and add the commercial sources that will help out with comparables and active listings.
You will want to add:
Paragon Commercial Comparables
Commercial Edge (subscription service created by the REBGV shows past sales)
You can also include a spreadsheet of the nearest broker listings
TIP: If you have a residential favourite list set, you can make a commercial one quickly by firstly clicking "De-Select All" then just choosing the commercial sources.
