It depends.
If you buy the right property it will increase in value which gives you options later on; if your salary increases substantially in 5 or 10 years, would you want to sell and buy bigger / better location?
Do you intend for this to be your forever home? Or might you want, in the future, to move to somewhere on the ground floor for old age, or buy with a partner? In which case you do not want your £60k to have lost value.
A rental? You move out you have nothing. A mortgage? You sell up and have your equity: what you paid plus increase in value.
If you can buy for £60k somewhere that you can live forever, or can be sure it won’t lose value: great!
But if mortgage free buys you a short lease / a declining area etc then it could be a better investment to buy ‘better’ with a mortgage..
Look at the economics of paying service charge and ground rent v a mortgage.
You can see from this thread that many inattentive pp have posted places that are auction/ tenanted / retirement / shared ownership etc and the genuinely affordable ones are few and far between.
Whatever you decide, good luck!
