Every new home has its special features. The ones that require homeowner operation will require that you know how to use them properly. If it is not obvious how a feature works, ask. Ask where the owner's manuals are and if there aren't any, make sure you know how to operate everything, as you may not be able to find out later.
How does everything work on the inside?
If the house is run on well water, know how your pump works, know where the water supply to the hot water heater is located and where the water main is if you have a leak. Try every faucet in the house to see if it works properly. Know where all the keys are. Are there also keys to things you did not expect? Know how to operate your automatic garage door, where the remote controls are, how all the other remote controls to things like ceiling fans work and how to set and turn off alarm systems. If you have a gas fireplace, know how to turn it on and light it and how the damper works.
Know what all the wall switches are for and make sure that they work. If you have an intercom system, know how to operate it properly. Where is your fuse box? How do you operate the thermostat? Will you know how to operate all of your appliances? This sounds simple, but some new appliances may have features you cannot figure out easily on your own. Make a list of paint colors and know where the leftover paint, pieces of tile and carpet remnants are if they were saved. Don't forget to check that all of the windows, cabinets and doors open and close properly.
How does everything look and work on the outside?
Make note of anything out of order with the landscaping, gutters, roof, driveway, sidewalks and fences. Check for evidence of water draining away from the foundation. There should be no pools of water forming to indicate that the grading was done improperly. Will you know how to operate the swimming pool pump? Replace chemicals? Operate the pool cleaner? Take off and put on the pool cover? Know where all of the switches for the outdoor lights are located. If you have things like a built-in outdoor grill, know how to operate it.
Who did the work?
It is a good idea to know the name and contact information for the builder in case you need to contact him afterwards. Find out the names of all the subcontractors who performed the various installations such as the heating and air conditioning contractor, electrician, plumber and roofer. This way, if you have any problems, you will know who is familiar with the systems installed in your home. If something malfunctions in some way it may have been caused by defective materials, which the subcontractor can replace.
There can be a lot to remember to look for during the walk through, but much of it is common sense. Think of yourself living in the home and needing to know how to work a certain gadget. This will help you know what to be concerned about and what to ask.
