I've never heard of tenants painting a
property when they leave.
And
As a landlord I definitely would NOT want a tenant to get a flat repainted.
You'd (as a tenant) end up spending $5k to mitigate $250 of unreasonable wear, that I could have had done at cost. Then you'd incur an additional $2k of costs to put the mess you 'randomly specified' right.... but it still wouldn't be right.
Don't do it; it's lose:Lose .
Just my 2c as an experienced landlord.
p.s. Please feel completely free to follow up the question/discussion; I'm in no way trying to 'shut you down' ok?
