Egress windows in a big basement

[Jared Smith]

I recently bought a 1500 SQFT house with 3 Bedrooms and 2 Full Baths.  This house has an unfinished 1500 SQFT basement too.  This basement has a hook up for a full bathroom and also has 9' ceilings throughout.  My plan is to put 2 Bedrooms and a full bathroom down there with 2 Egress windows (1 in each bedroom).  After all of this, the basement square footage should be counted in the overall square footage.  When this gets appraised, will they call this a 3000 SQ FT house with 5 total bedrooms and 3 full bathrooms?  Or will they call it something else?  I'm looking to add value to this home.  

Thanks!
