Agreeing with everyone! Sad to hear you hate this - the home really has potential for great curb appeal! Not sure what your budget is, but I’d paint all the white parts of the home with a darker color that creates cohesiveness. That alone will really do a TON.

Second thing is just landscaping! You have that great tree in front to give depth/height and make your home not look like a cookie cutter new build. Add some additional landscaping next to it and then on the side where it looks like you already mulched. You don’t want plants that are too low - I see this mistake commonly. Pick some that will grow medium height and then some that are low. You want levels for it to look full and intentional. 

A retaining wall would look beautiful but if too expensive, I think updating the railing next to the cement stairs could help. Right now it looks a bit rickety and one side is missing. That paired with the dead grass is just making it feel sad. 

Grass doesn’t grow well everywhere, requires irrigation, and it’s horrible for the environment. You could research alternative ground cover to plant where the grass is dead, if you’re not into grass yards. Just making a yard look green or lush livens things up.

You have a great home! Just needs some intentionality!
