Tart up a fixer upper

[TaupePanda]

We are - hopefully - buying a large fixer upper. Its pretty overpriced but the local market is bonkers and there aren't too many houses like this so it got competitive.
As a result, we have about a 50k hole in the budget to finish up the house to a great standard - plaster everything, new kitchen etc. The house needs a lot of work and we can cover the urgent things like fixing the roof and fixing up the basement flat. We intend to do that first to start renting it out to fill that hole.
This is a bit of a preamble to ask if anyone had any tips for cheaply making the rest of the house look nice as we'll have to live with it for quite a while (we think an old kitchen is worth it for the end product). A lick of paint will go a long way but any other thoughts?
Thanks

We might need photos. Just sayin.

Are you doing it yourself? ie, not paying anyone for labour? If so, it'll probably be ok.

Do it bit by bit, prioritising as needed. Finish things room by room instead of trying to do one type of job at a time with nothing getting completed as that's soul destroying. Bear in mind that if you rent out the basement flat a tenant is not going to want their life disrupted by your renovation works, especially not if they're someone who is at home working, etc.

Sorry, I should have been clearer - we'll do the roof and basement as these absolutely have to be done. But then we'll just stop - we'll have run out of money at that point. In an ideal world we'd rip down ceilings and pull out all the skirting etc right at the start. As it is, that won't be happening. We'll have to make do with what's there - strategically placed furniture will cover up holes etc... replacing the bathroom will be next on the list but in the meantime we'll need to be creative about making the space nicer - some of the ceilings look dreadful, for example. Anyone got a fun way to cover up cracks - I'm not really someone who is that inventive with this stuff. My last house was white and magnolia which was fine but in this place we'll end up depressed looking ag how trashed it is if we don't jazz it up a bit

I’ve moved into one, put a lot of pictures up, replaced the worst of the curtains for cheap plain ones, few plants, stuff on shelves, nice bedding etc.

Feels like home despite the 80’s kitchen, which is good because it’s not getting changed for years.

Ignoring the bathrooms 😂

Kitchen shops like wren have interest free loans if that helps?

I’m a bit confused. Are you going to be living in it or renting it? Do you have enough money to replaster or is literally all the money going on the basement and roof?

That's a horrible thing to do. Had it done to me.

Just to clarify: we'll be renting out the basement flat and we'll live in the house upstairs. We don't need the flat space - it's a big house even without it.
So, we'll spend the money we have making it water tight - roof, render etc... we'd do a good job on the basement flat so we can rent it out. Then live in the other three floors, which need renovating but we don't have that extra money as we've had to up our offer to buy it.
I know it sounds mad but we love the area we live in but there are only a handful of roads (I literally am taking like 6 roads) with big houses. The rest are 2-3 bed victorian terraces with 12 foot gardens and no parking. So if we want to stay local and have lots of space, a drive and a massive garden, we'll need to make do with sagging ceilings and walls that need plastering. We think it will be fine once we're in but would like to make it as nice as possible until we're in a position to sort it out.
