Even using 3-plex $/square foot would help.  

@Travis Foster I am told the most common profitable strategy is to add square footage or scrape and new builds.

When you remove it, does it also change your square footage of the living area?  

I would highly recommend that you read both The little red book on selling and How to win friends and influence people.

@Dave Madoch Without knowing your price range, areas that you're most likely to find affordable multi-families within the shaded portion of this map are towards the west(Logan Square, Avondale, Irving Park, Albany Park) and North(Lincoln Square, Edgewater, and Rogers Park).  

Paul Winka Hi Paul, If the floors don't have a lot of cupping or deep scratches, I have rented what I call a "square buff" sander from Home Depot and been quite pleased.

Hi Everyone,My husband owns a handyman business and in the last week we have gotten text messages (which are not uncommon for our customers), however the 3 texts I am referring to are scams and I just wanted to share with other contractors so that you are aware.Each of the 3 texts started out asking about a specific service our company offers such as one was hardwood floor install, and the third pressure washing, don't remember what the second one was without looking.The first one gave me a red flag when I asked where they found out about our company when they gave me a website our company is not listed on, but I played along to see where they were going with this.

The property is a little over 2,000 square feet and is a 4bd 2ba.
