The air stank.The air began to stink? This line is a bit of a stinker? pun intended. Try for something with a bit more oomph. Beat the brains out as to why he really sold you the house. Good storyline so make it work.

This is a good start for what could be a great zombie tale, but I agree with Marli about the “air began to stank” line. Also, Jason’s thought process might have worked better as a narrative paragraph rather than wrapping it in quotation marks.
