pricing of a twin home vs. single family home

[Amy C.]

Hi,

Does anyone know if there is a price differential (%) between a twin home vs. a true single family home.  We are looking to sell our home and of course, will consult a realtor, but in doing early research, I'm uncertain if I should deduct a particular percentage from the sold prices of similar sized homes.  There are no listed sold twins that are as large as ours to make a relevant comparison.

Thanks!
