Sometimes home owners with older appliances, water heaters, AC/heat systems offer home warranty plans as an incentive to buyers.
These home warranty plans typically run about $350 to $500 for a year of coverage. The biggest issue I run into with these plans is failure on the part of the buyer to read the plan coverage and exclusions to know what will and won't be covered. The plans vary from company to company, some have more exclusions than others. All have very specific rules for what the home owner must do if an appliance or system breaks down.
I've read that most of the complaints about these warranties is disputes between the plan holders and the companies regarding what is and is not covered
the quality (or should I say lack of) of work done by the repair companies that do the contract work for these home warranty companies.
Knowing all of this, my thoughts are that being offered a home warranty is a plus, but I would not base a decision regarding the purchase of a home on a $350-$500 home warranty.
