Your home is a pretty big investment. You probably worked hard to get it, and now is not the time to stop working hard to keep it! Maintaining it and keeping it in good repair will ensure many years and maybe many decades of continued enjoyment in your current home.
I always say that here in Southern California the things to keep an eye on are termites and water damage issues, though these are not the only things to maintain and keep an eye on. Have your home inspected for termites and/or damage. Repairs and fumigation may be an order, but well worth it in the long run. Perhaps schedule a routine maintenance program with a professional pest control company.
Have your pipes tested or inspected for leaks. Have your water heater serviced or replaced if needed. Adjust sprinklers so they do not hit the walls of your home. Have your furnace inspected and serviced and keep the filter clean. A roof inspection can detect any leaks and perhaps head off larger leaks in the future. It is far less costly to have a routine maintenance program than to wait for disaster to happen at inopportune times like when you are away or in the middle of the night. When you go to sell, a buyer will want to see that the home has been well-maintained and may ask you to repair or replace things if it is not.
A well-maintained home will reward you in money saved, added equity, pride of ownership and peace of mind.
