3 bedrooms with huge mst bath or 4 bed and smaller bath, WWYD?

[Stephanie Anson]

I am getting ready to purchase a home and would like to get opinions on what other people would do. The home was built in 1987 2500 sq ft and is currently a 4 bed 2.5 bath with a bonus room. The current master bath is pretty small, normal for the time frame built. It has a single stall shower and 1 bowl vanity. The closet is also not very big. So my question is do I bump out one of the bedrooms and convert it to a 3/2.5 with bonus? Other homes in the neighborhood that have sold were 4 bed but looking in sold pictures it looks like they had bigger master baths. I could justify costs beccause if I really decked out the baths I could ask more...what would you do?
