Even though you will want to get a thorough inspection from a company that specializes in that sort of thing, you can check a number of things on your own in order to have an idea about what may be wrong with a house.

• Have a look at the foundation of the house and any other cement for cracks or damage. Also, check the walls for any type of damage.
• Look for any evidence of water damage or moisture problems.
• Remember that minor settling crack in concrete will not affect the structure significantly.
• Be sure that all water is draining properly from the home and yard.
• In wet areas, check for a sump pump for foundation and sanitary drainage. 
• If there is a crawl space, make sure that it is dry. A wet crawl space is a sign that more water problems could arise in the future.
• Have the home inspected by an exterminator. This will save you from problems with rotting wood due to termites in the future. 
• Be sure that the flooring is in good condition.
• Make sure that the bridging and joists are constructed in a solid manner.
• Have a look at all of the walls for watermarks. This could be a sign of leakage in the home. 
• Inspect the attic and make sure that it is insulated and ventilated because this can lead to the loss of heat in the winter.
• If there is a fireplace, make sure that the damper works and that the chimney is all cleared out. 
• Have a look at the heating and air-conditioning to ensure that regularly scheduled maintenance has been completed. You can do so by checking the filters, the fan motor, and the bearings for maintenance. If they are in bad shape, you will have problems in the future with them. 
• Have a look at the hot water tank and note how large it is and what type it is. Also, have a look at how old it is, as older ones will need to be replaced. 
• Look at the electrical box to make sure that everything works properly and that the electrical system is good enough for everyday usage. Also check the wiring quickly, to make sure that there is no significant damage to it. 
• Be sure that the water pressure is strong enough in the home and check to make sure that all faucets are in working shape. 
• Have a look at all of the bathroom and kitchen fixtures because they should all be in working shape. This includes things like the oven, fridge, and any laundry and dishwashing appliances that are included with the home. 
• Be sure to have a look at the yard and make sure that it has been taken care of. Also, be sure that it has enough trees and shrubs to make you happy because having to plant new ones can be an expensive process. 
• Make sure that all fences are in working shape. Also have a look at the patio and driveway concrete because fixing this can also cost you a great deal of money.
• Confirm that the outside walls of the house will stand up to all of the weather conditions in your area. Also, be sure that the windows and doors are all in working order and see how difficult they would be to replace if need be. 
• Look at the roof for any significant damage. Also, look at the gutters and downspouts to make sure that they do what they are supposed to do.
• If you have a garage, make sure that the garage door opener is in good shape and works properly. Also, make sure that there is electricity and heating in the garage.
