Op I agree with the poster re furniture.
If I could show you what I've got for free from freecyle which is now usually on Facebook you would be amazed.
I've rarely brought brand new unless argos ikea etc the attractive furniture I had is completely free.
That includes child buggy, child beds wardrobe, drawers, dining table side tables magazine racks, out door furniture sets, toys picture frames!
What is a holiday? To many people on here it's a 5 grand all inclusive to Turkey
To many others it's a self booked, air b n b, easy jet flight to somewhere local? Costs a grand maximum.
Once you have some money behind you, you can save for everything and then you don't get into debt.
So if she wants a car it would be prudent to start putting away 50 quid a month or more for further car expenses: insurance, tax, mot. And get into that habit of saving for different things with 500 I would start a speficic car fund. Soley for what I've mentioned.
With 500 and a rolling 50 going in she would always have enough to cover expenses.
Even if she had to top up it would be a lot less than trying to find 600 at once.
Again for a holiday fund, she could start it with 500 and add to each month until she can afford a short break. With money going in each month she can accumulate for the next year.
Same with saving, get several thousand into a high interest saving account and add to it each month. Have some in pb and invest into the stock market.
Another thing she should do unless she's in line to inherit early is a sipp. Self invested personal pension. If she put. Grand in the gov adds to that but even if she didn't, it would grow quite a bit by the time she retires simply by growing in the stock market.
Doing all this would allow her the luxury of some small new stuff, and a small reasonable holiday perhaps 2 nights in a luxury bed and breakfast?
Set herself up for now and the future by spreading her money around her like a comfort blanket and a safety net.
It would mean she wouldn't have to worry about future bills or if she in two years wanted a break she can afford one.
