That's not the actual comparison. Any expense beyond principal will be paid by the renter, that includes interest, insurance, maintenance, tax, depreciation, etc, even if its not line-item billed like that. As well, basically every landlord is leveraged up to the neck, so you are also having to pay their monthly principal.
The actual comparison is
owning: principal (equity) + property appreciation - costs
vs
rental: capital gains - rent (principal + costs)
because both have "- costs", we can simplify to (principal + property appreciation) vs (captial gains - principal)
You have to compare the rate at which you pay principal vs the increase of the market **not the rate at which you can invest into the market**, because you still have to pay the base costs no matter what. The only way to have extra left over for investment into the market is to judge a rental for a smaller property against a larger one, or getting a sweetheart deal from a family member with a paid off property, which is just dishonest.
