EXCLUSIVE

Balki may be moving back in with cousin Larry ... a Pennsylvania bank has foreclosed on two of Bronson Pinchot's homes after he missed more than $270k in mortgage payments.

According to the court docs, the "Perfect Strangers" star stopped making payments on 2 of his homes 2 years ago, and apparently the bank had it and foreclosed. The homes were featured on his now-defunct DIY Network show, "The Bronson Pinchot Project."

Pinchot owed $186k on one, and more than $85k on the other. The bank now owns both properties.
