1. Change the locks. You really don’t know who else has keys to your home, so change the locks. That ensures you’re the only person who has access. Install new deadbolts yourself for as little as $10 per lock, or call a locksmith — if you supply the new locks, they typically charge about $20 to $30 per lock for labor.

2. Check for plumbing leaks. Your home inspector should do this for you before closing, but it never hurts to double-check. I didn’t have any leaks to fix, but when checking my kitchen sink, I did discover the sink sprayer was broken. I replaced it for under $20. Keep an eye out for dripping faucets and running toilets, and check your water heater for signs of a leak.

3. Steam clean carpets. Do this before you move your furniture in, and your new home life will be off to a fresh start. You can pay a professional carpet cleaning service — you’ll pay about $50 per room; most services require a minimum of about $100 before they’ll come out — or you can rent a steam cleaner for about $30 per day and do the work yourself. I was able to save some money by borrowing a steam cleaner from a friend.  

4. Wipe out your cabinets. Another no-brainer before you move in your dishes and bathroom supplies. Make sure to wipe inside and out, preferably with a non-toxic cleaner, and replace contact paper if necessary.
