The thing that pushed me over the top on renting was purchasing a house with an accessory dwelling that we could rent. Houses with rentable space often don't sell for that much more than those that don't have said space, but they come with an income stream.
That's an excellent point. Like I said in my original comment, it is comparable if you buy a place outright. I suspect if you are able to both extract rent while also save on your own rent, that may be the best of both worlds.
Perhaps I should take your idea and use it myself =D
