It depends how much you want to sell.
If you really want to, what some sellers do is go into a rental and put their stuff into storage.
But if the pool of houses you want is very low, you may not be able to move anywhere at all for a long time.
I don't understand your 'what buyers are looking for'.
Every buyer is different! Different needs.
Are you in the catchment area for schools?
Is there demand for your house? Is it a family 3 bed semi as a starter home or a £2M home for someone moving up market?
You must know what gets snapped up and what hangs around for months in your road/ town.
Buyers work on these -
1 Budget
2 Location
3 Type of house
4 Garden/ no garden, access to good schools or shops or transport.
You can only sell what you have!
Make sure it's maintained, isn't a do-er upper unless you're pricing it at that level, is clean and tidy, clear kitchen worktops other than for a few applicances, remove all products from your bathroom, put all personal stuff away for the EA photos, mow the lawn, clean the patio, repair anything that looks tatty (ie fences or gates) hide signs of pets (I wouldn't be keen on seeing litter trays or bowls of pet food), make the front welcoming and clean.
