Cost of fixing advisories

Hi I am looking to buy my first car and due to budget constraints want to buy a cheap car.

It is a Suzuki Ignis from 2004 and it has the following advisories:

Nearside front lower suspension arm ball joint dust cover severely deteriorated (5.3.4 (b) (i)) - Minor
Offside front lower suspension arm ball joint dust cover severely deteriorated (5.3.4 (b) (i)) - Minor
Nearside front valve stem slightly damaged (5.2.3 (j))
Offside front valve stem slightly damaged (5.2.3 (j))
Nearside rear tyre slightly damaged/cracking or perishing (5.2.3 (d) (ii))
Offside rear tyre slightly damaged/cracking or perishing (5.2.3 (d) (ii))
Oil leak, but not excessive engine (8.4.1 (a) (i))

How much would it cost to repair these advisories?

It also said there is a mileage discrepancy- is this a big issue?

I just need a car for a year to practice my driving skills, use it for shopping etc. no motorway or long journeys just city driving. And save up money for a year then I can buy a better car.

This is the car’s number plate if you want to check its full MOT service history: LT04XGG

Thank you!
