Commission Formula
Commission = (house selling price) x (commission percentage)
Simple Interest Formula
Interest = (principal amount) x (rate of interest) (time)
28/36 Rule or “The Mortgage Rule of Thumb.” Formula
Housing costs to qualify for most loans= (gross monthly or annual income) x (.28)
Property Tax Rate
Property Tax Rate = (assessed value) x (mill rate)
Assessed Value
Assessed Value = (assessment rate) x (market value)
1 mill
1 mill = equal to 1/1,000th of a dollar or $1 in property tax.
1 Acre in square feet
1 Acre = 43560 square feet
1 Mile in linear feet
1 Mile = 5,280 linear feet
1 square yard in square feet
1 square yard = 9 square feet
1 cubic yard in cubic feet
1 cubic yard = 27 cubic feet
1 square mile in acres & sections
1 square mile = 640 acres = 1 section
1 acre in square feet
1 acre = 43,560 square feet
Area of triangle
1/2 base X height
Area of trapezoid
(average of both base lengths) X height
Annual gross rental income
(monthly rental income) x (12)
Gross Rent multiplier equations (GRM)
Sales price = monthly rental income X GRM
Monthly rental income = sales price / GRM
GRM = sales price / monthly rental income
Gross Income Multiplier equations (GIM)
GIM = sales price / annual income
Sales price = annual income X GIM
Annual income = Sales price / GIM
Coast approach formula
Value = Land Value + (improvements + capital additions - depreciation)
Depreciation
Annual depreciation = beginning depreciable basis / depreciation term (number of years)
Depreciable basis
Initial property value + any capital improvements - land value
