Go to “Search Properties for Sale”.
Check property type: “multifamilies” in my case.
Select the location down to the zip code level if you like.
Press search.
When the deals come up, look for the tiny line above the first listing that says “Sort By”.
Click on cap rate and they will be sorted from lowest to highest.
Click on cap rate again and they will be sorted from highest to lowest.
You’ll see the cap rate in the summary.
Alternately I’ll add, call some local brokers. They will give you a good idea as well.
