Duplex deal or not. Looking for help.

[Dennis Haber]

Brick Duplex, asking price is 49000. Both sides are least
at $360 and $365. Owner pays water/trash only.

Duplex was built in 1930. Will need a roof soon,
Inside units are in fair condition, no evidence of water
or structural issues. No major repairs needed to
kitchen/bathroom etc.

Duplex has about 675 square feet per side, 1/1 with
detached 2 car garage in rear of property..

Based on the rents alone I would pass. Here the rents are 500-600 for half a house. Can you raise the rents? How are the comps? Does the roof need tear off or can it be reroofed?
