I would also recommend driving the area at night as what can seem like a not so bad street transforms after dark as the partying picks up and the students get  routey.  

My parents, who found it, say it could use another coat of paint on the walls to mask the old colors and hopefully the mild smoke.

Additionally, the rooms are small, narrow and dark. 

Oh and for what it's worth unless it is just a smoking hot deal please don't find a house on the MLS, negotiate it down a few thousand, get it under contract, then try to flip it to an investor. 

(ie.. the doors open, the windows work, the furnace works, and smoke alarms are functional with 10yr batteries).  

Envision little faces pressed against the bars through the smoke...

With that be said I can image it has no CO2 alarms, smokes or exhaust fan for bathroom.

Dark pictures of cluttered houses get less traffic and thus less offers. 

In either scenario, I am very transparent and keep everyone in the loop during every phase of the transaction so no one is left in the dark. 

When I charge $5 for a bulb or battery for a smoke detector don't complain.
