Part of the value of a house is the value of living in it, the rent. It costs to live in a house, and the amount it costs is the rent. And this is true whether you own the house or if somebody else owns the house.
Living in a house you own vs renting out the house you own decreases your net inbound cash flow by the amount of the rent; rent is paid, even if it is your house.
this is very basic economics, very basic finance, but, as understood by somebody smarter than all of you, who has kindly taken the time to explain it. You are welcome.
(Consider living in a house that you do not own, and paying the rent. Now, marry your landlord. What has changed? Answer: nothing, the rent you now save is also income the couple has now lost.
(you will need to make adjustments for depreciation allowance for investment property, tax deductibility of expenses, etc. but that's details, not conceptual. Do you suspect that these line items actually could make the difference between this being a wash vs a no-brainer money machine? they don't. If tax deductions make landlordship more (or less) advantageous, then the market will shift landlords⇔tenants till a new equilibrium is achieved where the rents and deductions balance out, with people living in all the same places. no value was created or destroyed, except less govt interference in markets is better, dead weight losses and all that))
