It's difficult for renters, but as a landlord I'm always careful about what the tenant is permitted to do; there's many good reasons for some caution. Having said that, I'm a generous landlord and am happy to work with tenants and their needs/wants within the framework of my investment needs and what's right for the property itself. Balance. Unfortunately, some tenants only think of themselves and get uppity when I refuse permission to do things, and I deal with that too.
When you get your own place you'll be able to DIY to your heart's content.
Haha yeah... I was always a good tenant, did most stuff myself except when a big flood rotted an entire wall.
That's the fun bit - though mostly in the garden for me =D
