now lets talk about renovations, additions, etc, etc.
I was just doing rough numbers. They can change quite a bit based on where the house is and what it has (eg pool adds ins and maintenance costs). I used 6000 tax, 4000 insurance and maintenance of ~4000. Some years may be lower, other years much higher.That seems high. Though I'm not in the city. On my $900000 house, insurance and taxes are about $520/month. Renters are paying those costs for the owner on the property.
Maintenance cost would be very difficult to nail down to a monthly cost. Could be next to nothing for years then be quite high. Depends on the quality of the house and if things have been neglected.
Obviously it is more to rent than own once the mortgage is clear, the point was it is not zero to own, it still costs an decent amount of money just to keep the asset. If lightcycle wants to take off to Thailand for a year, he rents a storage locker in he boonies for $200 a month and still has $~12000 in his annual travel budget that the homeowner would be spending just to keep the house. His investments continue to grow with no carrying costs.
As the discussion goes on, we have had good arguments on both sides and some decent modeling showing outcome over time. I think it is reasonably clear at this point that either option can win financially by cherry picking time and place or equities. They key to financial freedom is save your money and get it compounding somehow. You will be ok. As for renting vs buying, I have a clear preference for me but it is based more on personality and risk aversion than being the financially optimal decision.
