@turboizak I think that there is a fatal error in your analysis.
You count your $350,000 deposit as an expense when purchasing the property, but then don't count this as a gain when selling the property.
You get your $350,000 capital back when you sell the property, so this should show as part of the net gain realised when selling the property.
The only expense related to this use of capital is the opportunity cost (the difference between investing the $350,000 in housing vs stocks). You are assuming an interest rate of 7.25% on the cost of borrowing, and a return of 8% on stocks, so the opportunity cost is 0.75% return compounded over 10 years.
Happy to be proven wrong, but I don't think I am.
