 If total is 4%, then, calculate the amount for traditional way for a house sold in 400,000, you'll find it will be 4% for total (100000*0.07 + 300000*0.03)/400000 = 0.04, so the same for both.  0 ^" L4 l# n$ K* f7 i0 ~: V/ r3 w

 Let's try to calculate the rate for the traditional way: y = (0.07*100000 + (x-100000))/x => y=4000/x + 0.03
