Buying now, mortgage free or not?

NameUnavailable

I've sold my last property and am looking for a new home. I have enough equity to be able to buy a smaller property (1 bed flats) outright, or can get a mortgage of say £50K to buy something larger. 

I'd love to be mortgage free, less worry about job security etc., but then again should I get a better property and mortgage now whilst it's no issue and there are low long term fixed rates available.
