Or, are 3 bedroom houses with an office or den, selling for more than a 3 bedroom house without the extra room or are they selling the same as a 4 bedroom.Or, in newer developments (typically master planned communities with multiple builders), Buyer/s can be more informed and really see the difference between builder quality and features, and that can reflect fairly clearly in the prices and Buyer's appeal. 

Then, if there's a need, and your market checks out then start getting it furnished and add all of the amenities, towels, body wash/soap/shampoo/conditioner, washer/dryer, etc. 

Anxiety is the biggest killer for both business ventures and our bodies.
