4br to 3br to add master bath

[Byron Bohlsen]

I realize it can be location specific but in general do you guys know if it increases the value of the house to take a 4 bedroom house and convert it to a 3 bedroom house to add a master bath and walk in closet where there is none (and probably increase the size of a not very big master bedroom). 

House I am loooking at is 1800 sft, 4br, 1.75 bath.
