In my humble opinion the answer is no. It will most likley help the place sell faster and perhaps for a little more money but not for $17,000 more.
For comparison, if you spent $20K on a pro to come landscape a home, the appraiser only adjusts the value of the home for the cost of materials, not labor.
In very few cases do you see a return that equals or exceeds your investment into the home. I always suggest to sellers that they focus on making sure everything is working mechanicly and physicly in the home first, then address cosmetic issues.
I am sure other Brokers may disagree however this is just my opinion, take it for what its worth!
