Hi. Improving your kitchen can help to sell your home. The kitchen and bathroom are normally considered by buyers to be the most expensive rooms to modify and if it looks like more work will have to be done, it could well hamper your sales. Many people want the work to be done so they don't have the hassle and expense.
It might not increase the value of the property, but you wanted tips on making it sell, therefore not presenting it in the best light could well put people off or worse force them to give a lower offer or even worse than that, not offer at all. It's stressful enough selling a home, so try to make it easy on yourself.
Also make sure the garden is in good order - gardens can increase the property value by up to 5k. These days, the garden really should be treated as an extra room, particularly when many of us live a fast-paced life, we'll need somewhere to relax.
Good luck!
