I do these all of the time- if this is a rental, middle class sort of area; paint the cabinets, new hardware, new lighting, new appliances, resurface the counters and new flooring and all of the sudden it will look like a million bucks. 

Maybe the curtains, ceiling, cabinets, baseboard and trim, or a variety of places.You could try running an ozone generator to see if that helps.

Installed all new cabinets, countertops and appliances.

I have been installing granite in all of my rentals for a while now because they are going to hold up longer than the cabinets will.

I was hoping to get some professional opinions on the following renovations: Staircase (3 apartments), kitchen cabinets, floor, boilers, a single siding beam that is completely misplaced. ( New Heven, CT)
