Question: When Phoebe is on the phone with Ray, he mentions that the Ghostbusters fire house is now a Starbucks. In the post-credits scene, we see that Winston has purchased the fire house so the Ghostbusters can get back to business, but the fire house looks like it has been abandoned for several years and no other company ever took it over. Did I miss something here?
Answer: Perhaps nobody wanted to take over the place for a few reasons. Historical purpose, high cost... hauntings.?
Answer: It's been 40 years since the Ghostbusters disbanded, Ray mostly likely passed by the old place and saw a Starbucks there. It has since shut down.
But they left the ghost trap active? Not likely.

Question: What animal power did Newt have, bursting into flames, and what animal power did the girl that turned into ice have?
Answer: Their power is thermoregulation. I don't think it's stated which animal it came from, but any animal that thermal regulates (i.e. warm blooded animal).
Sharks do it when they deep dive to keep their organs from freezing.
Answer: Ray was probably being sarcastic, and was simply making a general comment about gentrification in the area.
