Remember, there is no such thing as a perfect house.  As any home owner will tell you, something is always in need of fixing or upgrading.  What you want to do is protect yourself from any unexpected large expenses.  You should also arrange for a home inspection to be made by a professional prior to your purchase.

Another protection plan for you is to purchase a home owners warranty.  The cost is minimal for the wide coverage of this plan.  Please note that this coverage is for one year from purchase unless you extend it.
