Having said that, the furniture should be in good condition and shouldn't "stand out." For instance, not to stereotype, but older folks sometimes have large, overstuffed, furniture, sometimes with large prints. This tends to scream out: "older people." (Understand, everyone: I'm not talking about age discrimination, Fair Housing, or anything similar. I'm talking about the buyer's perception that the house isn't for them because it's for "older people.") So: good condition, "neutral" furniture. If you don't have any, a stager can provide it. Or you can rent, short-term, from a furniture rental company.
Hope that helps.
It is very difficult to give you a choice one or choice two answer.
We really have to see the house because the answer really depends on the house, the surrounding, the neighborhood and the kind of furniture, accessories you might have in the house.
I think the best advise I can give you is to ask a Realtor to come in and give you a market analysis on your house and general idea on what you should do. Realtors will mostly do this as a free service.
