If you want a potential home buyer excited from the start, you need to have curb appeal in your front entry and street view. When they pull up to your home or see the first online photo, your home needs to stand out as a well maintained home with a beautiful landscape.
As you can see from the photos below, the specimen cacti in those homes will only grow and mature over time, which increases the value of your home. Over the course of 20 years, does a kitchen upgrade, bathroom upgrade, pool install, room addition, or solar panel install increase in value? A professional landscape that is well maintained (watered, fertilized, and treated with disease prevention) will mature and even become better looking over time. When you make the investment in a 12 foot organ pipe today, what do think that organ pipe is worth in 20 years?
Before you start your next home improvement project, remember great landscaping is the only one that increases in value from the original purchase.
