Sewer Connection to Alley vs. Street

[Julian H.]

Hello Everyone - 

I invest within the Lehigh Valley of PA where the homes are older (1900's) and had a question regarding the sewer drainage.  In one duplex in particular (Allentown, PA), the seller pointed out that the sewer line went to the alley and not the street (front of the home faces the street).  I didn't know if this was his way of discretely disclosing something to me of it doesn't make a difference at all....does if effect the value of the property as well?

I look forward to the replies, hopefully someone has a nugget of information.
