off market abandoned property details

[Wendy Busa]

I have located an off market, abandoned property and I am trying to find out specific details about the home so that I can make sure the repair cost that I figure are accurate; In particular, wondering if it is on a septic tank. 

I have looked at the county assessors site and the only info I can find is the acreage. I plan to contact the owner, but she is elderly, so I am not sure how much information she can provide.

Is there any other resources that would show information for a property that is from 1912? 

Thanks.
