30% CAP on potential contaminated site

[Dinesh T.]

$8000/month rent on 200K investment. Fully rented. Talk about the 2% rule. The catch is that a neighbors property (dry cleaner) is potentially contaminated. Seller is insisting on cash purchase as bank will not finance due to environmental concerns.

Is this property worth further investigation or should I not even touch a potential contaminated site with a 10 ft pole?
