One thing we don't know about is how many bathrooms, where they're located and if they are attached, etc.
As others have mentioned I think it depends on where the bedrooms and baths are located. Two bedrooms down with two full baths down seem to have good demand either for multi-generational families living in the same home, or parents wanting smaller children on the same floor. I'm also with the agent who asks why it would cost more to build, (unless you are adding a bathroom). If everything is the same, but you are just combining two rooms into one, it should be less. One less wall, one less door, etc and that should cost less. One less wall should not take any kind of architectural redesign. Anyway, good question and make sure you use a realtor during your purchase. Every day we get questions about how the builders screwed up this or that and how can they fix it now. It's always a good idea to take a realtor with you on every visit to the builder and especially the first time. If you haven't signed a contract yet, now is a good time to enlist help. For a whole list of common issues we have seen with builders see me website at http://www.teamlynn.com and click on the new home link. No need to go at this alone, have someone fighting for you in your corner at typically no cost to you.
If you are purchasing this thru a builder you need an agent that works on your behalf therefore you area also covered under your agent e & o insurance policy.
Have you also had your realtor do all the other required research prior to signing the sale contract? Determine what is your best interest. Allot of details need to be involved prior to doing this.

BR up would also have a bath to share. If you dont get a master bath, you dont have a master BR, in my opinion. If so go the 4 BR route.

The trend of the homes that are really selling the best are those with the master on the first floor and a second bedroom on the first floor. Of course, you would need another full bath on the first floor.
This is very convenient for people that may have elderly parents visiting or living with them that cannot do stairs or if someone is sick and cannot do stairs.
However, a master bedroom up and one down would not add much to the value but make it much more appealing for resale for people that want to be on the same level with the kids while they're young, etc.. 6K is not bad for adding another bathroom either, I would do it if these were your only choices.
