- P, `3 s. S+ D/ M6 m6 r " U1 n- x& R! t% a/ W7 v. KThank you for your reply . I know there are some people like me meeting the same question. Now I need to know which number the City of Edmonton using for the property assessment. If one day I sell my house, I will write the MODEL SIZE(because I paid this money to the builder), but the city uses the net area (not includeing the stairwells). The buyer could say that I am a liar???
