I am truely surprised by having Fannie Mae dictating of a home or total living area to be definitive of heat and/or cold air as mandatorily "built-in" (or pehaps not). Mustn't stand alone heaters or coolers work? How about wall mounted air-conditoners and/or heaters sufficing the general outlay or definition of a "heated" room or is it necassary for any room to must have heat and/or cold seasonal air to be counted within the overall definition of "living area"? Can a fireplace alone in a living room accomodate to justify all other rooms as heated to justify the entire "living area" or must every room have a fireplace, individual heaters, base heaters, radiatiors or central forced-air heat? Please be adviced that I am only debating/discussing matters for the sake of proper understanding, and not what Fannie said this and Frankie said that?
