Walgreens ground lease

[John C]

There is a listing for a walgreens ground lease I noticed on the internet. The walgreens is on a hard corner in the outskirts of the city. The asking price is $2M with a 4% cap rate, basically it's only making $80K per year for quite a while. I don't understand, how did it come to this? How did walgreens work out a deal were they only pay 80K for years to come. And why would the owner allow this deal to happen?
