One way is to stop thinking you 'need' new stuff just becuase it is dated.
Our kitchen and bathrooms are dated - especially the kitchen. The floor is knackered. I've hated it for years. Finally came around the the realisation we will never afford a new kitchen and started to really show it love. I keep it clean and tidy, polish the horrible floors and have filled it with eye catching beautiful plants and crockery. People have started saying it looks nice again. Haven't said that in twenty years!
Same with bathroom - scrub it until it gleams and put a few cheap but pretty things in it to catch the eye.
Can you rent a Rug Doctor and steam clean the carpets? Makes a massive difference. Then put down a few cheap rugs (or free from Freecycle - ask for rugs in neutral colours) over any bare patches or hideous patterns.
Can you just mend the fence? Ask a handyman to quote for mending it rather than a new fence. Or take it down entirely and put up wire between posts then train plants along it.
Take the gate off the hinges if it's broken and have no gate. We did that. It looks nicer.
You can also ask for paint on Freecycle. If you ask for a particular neutral or common colour, you might get some from several different sources - a few half pots of gloss white will make a massive difference to all rooms if you just do the woodwork.
I know it's not ideal but deep cleaning, mending, prettifying and using Freecycle or similar make a massive difference. I even know of people offering good washing machines in freecycle because they've moved into a house with an integrated one. Just put your wanted posts into not only your area but any nearby very well-off areas. Unlikely but worth a shot.
Spend any money you do have on the absolute essentials like the roof leading and a new washing machine.
