We would usually do some flower boxes and do some mulch and perennials around the front of the house.

I usually clean it, and make sure it has the best curb appeal possible, whether with fresh mulch out front or with flowers to set the impression.The next thing is for any improvements, I have an outline of the improvements made, and the amount spent.Finally I try to come up with the best comps that match the property.I put that in a package and I make it available to them, without being pushy.Most appraisers appreciate it.

@Josh Flowers I'd encourage you to read Real Estate Wholesaling: The Ultimate Guide here on Bigger Pockets as a starting point.

The New Management signs are also really helpful.Landscaping and flowers are also really good.  

Remove,HOWEVER,If you can turn an eyesore into a feature it would be awesome.You could plant a bunch of climbing roses and cever that entire thing in bulging flowers of all colors.It would be very beautiful, and functional.The smartest thing to do however is to remove it simply because most likely the people that will buy your hose won't need it...

Some have even gone above and beyond by adding flowers and other little things.

I don't like mowing the lawn and landscaping the front flower garden.

Flowers /color out front and a little bit of staging with accessories

She's already gone out to buy some flowers to plant.

A few flowers, getting rid of old, ugly, overgrown bushed and adding some fresh mulch can go a really long way to making a property look nicer - without trashing your wallet.
