For a fair number of people it is simply not possible to get their finances in order without massive life changes. Doesn't mean they shouldn't do it, for values of "shouldn't" such as "wouldn't be better off and happier, five or ten years down the road".

> I don't think that becoming a life-long renter is a smart choice either.

As someone contemplating if not life-long then seriously long-term renting, serious question, why do you not think it's a smart choice?

Firstly, there is a lot less security in renting. I can be evicted with a months notice. While I'm young that's part of the trade off but when I have a family I wouldn't appreciate that level of control over my life being in the hands of my landlord.

The second reason is the fact that when I fully own a house I will feel more financially secure. I won't have to worry about making rent payments for the next X years of my life and I'll feel better prepared for unforeseen circumstances. I might be able to achieve the same security by investing my money in other areas; but I much prefer investing in something tangible.

if nothing else, most landlords have loans so you're subsidising their loan (so paying at least as much as you would if you had the loan).

Perhaps, not certainly, but is that a drawback?

A mortgage is essentially a huge long-term bet, renting is a smaller, shorter term bet. The owner is betting that everything lines up nicely: the value of his property stays put or rises, nothing bad unexpectedly happens to the property, undesirable people don't move in around it, a whole-sector bubble doesn't pop. As a renter, there is no commitment: if the house is outdated you can move to a newer one with far less hassle; you don't have to worry about cost of maintenance; if you move during a bubble you can move once again when the bubble pops and pay less. The owner may end up with a property in 20 years if everything goes well, but a renter will never be underwater.
