Hey nice post and simple arithmetic that a simpleton like me can understand.
One thing you didn't factor in is appreciation, minus realtor comm when sold, which need to be considered for the big picture.
I thought that might come up. Here are the numbers:
Average U.S home appreciation, 1987-2005: 5.36% (NAHB)
U.S median home price (Mar 2006): $232,500
Home price after 30 years at 5.36% compounded: $1,113,514
But how much did the homeowner have to invest?
Home cost: $232,500
Interest paid: $275,609
Realtor's commission (1%): $2,325
Property tax (1%): 2,325$/yr x 30 years = $69,750
Home insurance (U.S. Avg): $677/yr x 30 years = $20,310
Maintenance & Repairs: $5000/yr x 30 years = $150,000
Interest deduction (30%): -$2,756/yr x 30 years = -$82,680
Total cost after 30 years (incl. down payment): $667,812
Net profit: $1,113,514 - $667,812 = $445,703
Based on the average home appreciation from 1987-2005 of 5.36% per annum, you would increase your investment by 66.5% in 30 years after costs. That averages out to 66.5% / 30 = 2.22% annual return on investment over 30 years, which doesn't even keep pace with inflation.
