Yep - investing in property is ok in my opinion, but I'd never consider my home an investment. Our house was an absolutely wonderful find to live in for 10 years, but if I was considering it from an investment point of view, I wouldn't touch it. The two have totally different characteristics. (personally, I'd probably do commercial property rather than residential if I was investing, but that's a different thread)
Yes, I think the property-owning obsession in this country (UK) is ridiculous. The newspapers are full of "millions of young people won't be able to buy a house until they're nearly 40. Oh noes!" bullshit. So? Why the hell do you want a house in your 20s, it's just something else to worry about.
Unfortunately, if you have kids (and thus need some stability) it's a different matter here - nearly impossible to get a rental term over 12 months, and finding decent rental property is very, very hard in the South East.
