Help analyze a property.

[Moshe Yadgar]

Dear members, 

My name is Moshe, very new to RE investing, reading and learning as I go. I was able to meet a wholesaler with the following deal: 

Location: Shamokin, PA

Age: 50 years

Units: 10-2 BD's and 10-1 BD's

Average Rent: $600 to $750

Property is vacant but has high demand for tenants

Market rent same as average rent

Semi pitched roof needs minor patching

All utilities are metered for each unit both electric and water - tenants pay all utilities

Property tax: $2500 a year

Needs full renovations

Terms: Pay in full $275k  or 100k down with 4 years of installments for total $325k

I would appreciate any pointers to help me analyze this deal.
