Are you basically calculating the repayment portion out of the annuity?
I wouldn’t necessarily agree that everything except interest counts towards the return in real estate? Or is it really calculated that way in the financial world?
But there are maintenance costs and possibly also depreciation of the property when it gets older, right?
My example is highly simplified and kept brief.
Effects from maintenance, non-allocable ancillary costs, etc. are present in all scenarios and largely independent of the interest rate. Depreciation is only relevant with really old buildings; with young buildings in good condition, depreciation effects are positive for taxes, and even a value increase that only corresponds to the rate of inflation would already cause the equity return to explode.
I just want to point out that the world for capital investors is different from that of private owner-occupiers.
In my view, the question is particularly interesting with single-family homes. These are mostly built and lived in privately.
