Bleach will get it, then use an oil based primer before repainting

If the utilities are not on, you can put in your offer that the deal is subject to the utilities and fixtures are all working in proper order.Obviously check for cosmetic repairs needd, such as sheetrock repair, flooring replacement needed, will you have to replace or repaint the kitchen or bath cabinets or countertops?

If the units are smaller, that cost seems plausible, but would be on the lower end of the range here.Remember that is only the cost of the electrician replacing existing circuits and does not include the repair and repaint you will been to do to walls and ceilings (hopefully the electrician is not planning to surface mount).  

With smoke stains and other smells I've found that priming the walls AND CEILINGS with an OIL BASED primer (not water based) did the trick before I repainted.

I feel that when they leave I will have no choice but to repaint the entire house.   

If you own an asset 20+ years, you will likely have to replace the kitchen and bath, roof, repaint exterior a time or two, etc.  

It's the outside of the property that could be better -- the mansards' tiles don't look great, the windows don't look so good -- so we're repainting the doors in front and placing sun shades over the windows.

Let's put it like this, a 1950 mustang all new repainted and update it or a 1990 mustang with no updates , what is more likely to brake down sooner?

Collecting rent alone is a hassle, much less the increased maintenance by low income not knowing how to take care of things, and then how time intensive turnovers are, like almost always needing to repaint and recarpet.The street I live on often has crimes reported, that alone doesn't give a complete picture of the neighborhood.
