Steel or fiberglass entry door for city rental property?

[Devin Berrian]

Hey BPeople. Finally closing on my 1910 duplex tomorrow in City of Poughkeepsie, NY. Not the worst street (by far) but still some shady looking pedestrians passing through. I'm at Lowe's wondering...do you pay the extra $500 for a stainless steel entry door? We have a back door to replace too. We have about a six month rehab coming up and plan to put "no copper on premises" signs up (thoughts?). 

Thanks.
