Doing up house to rent and I’m a novice

[Bodear]

I’m posting for any and all helpful tips you can give. I have a house that is a bit of a mess. I don’t think there’s anything structural but years of not being looked after have left it looking very VERY tatty.
I’d like to rent it out and I know it needs doing up but I don’t really know where to start! How do I make a budget? Who do I start with? I have no idea!

I would do it unfurnished which suits more for families who would have their own things.

You'd be constantly asked to remove x or y items otherwise. House shares & students tend to need furniture

White walls is easiet as there are a million shades of cream/mag and you can touch it up much more easily.

Neutral flooring.
