Dp and I rent our flat in London. For a variety of reasons, but mainly because with interest rates so high, just paying the bank's interest on a loan that big would cost more per month than our rent!
I've had comments from family and friends back home in the north saying stuff like "Oh you rent :/ " or "Oh renting is just wasting money". "Oh so you don't own your home then" and even "It's not a home unless you buy it" but some of these people have huge mortgages on the properties so they hardly own them. For what it's worth, DH and I have more in investments than many will have in equity or their deposit etc. So renting can and is a sensible choice for many, especially in inner London
