There's an old saying, rent money, spent money, you'll never see it again.
On the other hand the house you buy for £,000 could be worth £400,000 in thirty years, so even with interest you could be up £200,000 or alternatively you could rent at £600.00 a month, £7200.00 a year works out at over £200.000 in rent to some rich landlord, I know which way I'd go.
