You don't have to roll an actual red carpet down your walkway every time you show your home. (But it wouldn't hurt!)
The most important thing is to make sure the journey to your front door is a pleasant one. That's when buyers form their first impressions.
Make sure the walkway is swept clean and is clear. The last thing you want is for a buyer to trip on a broken paving stone, or get matted clumps of freshly-cut grass stuck to their pant legs!
