Philedelphia investing

[Patricia Bercy]

I have been looking into the Philly area for investing, I have also taken a look in the Allentown area close to lehigh university.  I ran across 2 potential deals:

Lehigh: $70k-- 3 bedroom, single family, rents can be @$899/month (no tenants yet)

Duplex in Philly-- N. 12th st. tenants in place total income $1475, cost of home $85K

Which deal is better?  Any advice is greatly appreciated, thx.
