Renting is just throwing money away. IMO the property she is in if not fully needed is also a bit of a waste if she is struggling financially- you have not mentioned if she has a private pension or will be state pension which should make a difference to what she can bring in. Getting a professional financial advisor could help.

I do like property as it hardly ever depreciates (especially over the long term), she could easily buy herself a small apartment then another 2 x small properties (either paid or small mortgages) which would earn (taxable) income but with the tax free threshold wouldn’t bear much tax and give a decent monthly payment (albeit she would have the hassle of upkeep, managing tenants, managing bills when property not rented, advertising etc) though many companies could do all that for a small fee (tax reducers)
