Evaluate where is a NEED or WANT.  First look at curb appeal, acceptable wall colors, kitchen and bath finishes and floor coverings.  Change these if they need doing.  Be sure the roof and mechanical components are working as they should.  You may have to replace those.  If you go into major renovations to increase the price of your home – YOU MAY NOT GET THAT RETURN ON YOUR DOLLAR.  If you want to do renovations and plan to live there for several more years that is fine.  Remember a buyer has to pay for an appraisal, which may not reflect all the money you put into renovations.  Just look UPDATED and offer a home warranty to cover the mechanical items for usually a year.
