Answer:
Step-by-step explanation:
Salvage value = price(1+i)^n; i -interest rate; n-time period
Salvage value = 1,200,000*(1+0.05)^25 = 4,063,680
Monthly rent = ((price+building cost) - salvage value)*(i(1+i)^n/[(1+i)^n-1]) +
+ i*salvage value + maintenance cost*12*number of buildings + insurance and property tax) * (return/[(1+i)^n-1]) =
((1,200,000+4,800,000)-4,063,680)*(0.12*(1+0.12)^25/[(1+0.12)^25 -1]) + 0.12*4,063,680 + (100*12*40) +400,000)*(0.009489/[(0.009489 +1)^12 -1]) =
= (6,000,000 - 4,063,680)*2/16 + 487,641.6+ 48,000 + 400,000) * 0.0791 =
=( 1,936,320 * 0.125 + 487,641.6 + 448,000) * 0.0791 =
= (249,398.016 +487,641.6+448,000)*0.0791 = 97.636.63
So the minimum monthly rate is 97.636.63
