Stage the home if you can. A good staging will garnish you better photos, attract more qualified buyers, and help to sell the property for you.
All the homes we remodel or flip get staged for this reason. Think about the frame that a buyer is operating in as they shop. Viewing a home is an experience in itself. We want that experience to come as close to "I could live here. I have to have it." as possible. We even use scented room sprays before showings so that ALL the buyers senses are attacked as they go through. Things like this will help the property stand out in the buyers mind when they viewed 4 other homes that random Saturday.
I know you said the property is slightly dated and you are listing below what the comps are, but in my experience you can bump up what a buyer is willing to pay if you utilize staging.
So, yes. If possible I would stage the home.
Our ROI has grown on the staged properties versus the non-staged. They also seem to sell quicker (I know most markets are hot right now as it is, but thats just my perspective)
Should you stage - try to use a professional that does it often. Ask how long the contract is for the staging. What if you need to extend that contract for some reason, is it an option. Make sure they showcase the rooms appropriately - for example we had a large room that lacked a closet in a flip soooo it wasn't a "true bedroom" - so that room was staged as an office.
Hope this helps.
