Walk throughs are important

Walk throughs are an important step in the final stages of closing on your home purchase. It is essentially your opportunity to make sure everything with the property you are purchasing it is as it is expected including broom-swept clean, free from the sellers possessions and complete with any inspection commitments.
Given the proximity to the actual closing day, it is easy to get restless and rush through this step to just "get it done." However, you don't want to underwhelm this step. Here are a few considerations for you to make sure you get the most of your final walk-through.

Clarify Up Front: Don't make the mistake of making assumptions about "what is included" only to be surprised on walkthrough. To help this, spend the time with your real estate representative to clarify what fixed items are included or excluded... pay special attention to tvs/mounts, lighting, window treatments, etc.
Take Your Time: Set aside a good hour to allow yourself adequate time. You don't want to be rushed through this step.
Timing is Everything: Make sure that it has been confirmed that the seller's stuff has been moved out and repairs/cleaning have been completed before going through. Typically the walkthrough is done 24-48 hours before the closing date/time.
Have a Contract on Hand: Having your contract and any subsequent documents with inspection or other agreements with you is helpful to refer back to in order to ensure that you have the accurate information to compare to.
Verify repair work: Using the documentation from the agreement, check any items that were agreed to be fixed as part of the inspection process to ensure the work has all been completed. If it is something that was required to be completed by a licensed professional, ask for receipts/verifications in advance of the walkthrough.
Check things that close: It's always a good idea to check windows, doors, cabinets, drawers and other items that open and close to make sure they are fully functional. Also check to make sure any locks are functional.
Heating and cooling: Check to make sure that the heater/air conditioner as still fully functional. 
Appliance check: Check all kitchen appliances to make sure they are functional and in working order.
Lights out: Check to make sure that lights are working (you may even want to bring along standard light bulbs as a way to make sure a lighting failure isn't just a burnt out bulb.
Power Up: You could also test electrical outlets if you bring something that can plug in (a phone charger is an easy option).
Let the Water Flow: Check to make sure that faucets work and toilets flush. It is also a good time to make sure you don't see any unexpected leaks.
Screen for Screens: Make sure that all screens are in place or available. At the same time, make sure that if there are removable hurricane shutters that they are all accounted for wherever the seller has them stored.
Things attached: Check to ensure that any items that were fixed and expected to remain are still in tact (tvs, mounts, light fixtures, window treatments, etc).
