> Unless you think landlords are running a charity, some part of your mortgage is going to them as profit (over a large enough sample of renters anyways), and some percentage of your rent is covering 'bad tenants' (which you're not, right?).

You can make the same argument about a bank not being a charity and making a profit from selling you a mortgage (both are true but are not helpful indicators about rent vs buying). Similarly the interest you pay is insuring the bank against bad debtors, which you presumably will not be.

> With home ownership though, things like a modern kitchen, a shed, new laundry machines not only better your life today but also (likely) have some value add.

You can improve your living situation in a number of ways when renting. If you want a new kitchen or bathroom, rent somewhere new with those things. Renting also affords you the freedom to leave when things go from good to bad (crime, noise, building ammenities, etc.).

So when you rent you have to cover the landlord's profit/risk and the bank's profit/risk because the landlord probably has a mortgage.
