No masterbath. How much does this effect selling price?

[Patrik Kusek]

I know and understand that buyers want an en-suite. I know I do. However with this deal it's not a viable option. My realtor is optimsitic because property in this area is very scarce and demand is high. She's looking for comps that don't have a master bath. Any though thoughts on how to price? I know she'll have suggestions but I thought I'd ask here as well. For instance I know that properties on busy streets can be up to 10% less than the same house on a not busy street. Is there a general rule to calculate no master bath.
