It'a a lot of money for a poorly decorated run down flat.
The carpets are worn and dirty and need replacing, the kitchen is dated
The woodwork on the stairs is damaged and needs stripping and painting
The fencing in the garden is crap and needs replacing.
Basically it looks like a money pit.
The photos are.poor, the description more so...for a leasehold the length should be stated. And I think 250 is great for a mortgage lender but if it doesn't state it, I personally am going to assume it is under 100 years which is then more difficult to get a mortgage on.
