Droopy young maple tree?

Hello! I would be so grateful if anyone could offer any advice or insight. We moved into a new home about a year ago, and the builder planted a maple tree in our backyard.

We drenched it with water over the summer last year and tried our best to take care of it, but the leaves are very droopy no matter what we do. It went dormant over winter and is coming back now, but looks droopy and sad again. Is this fungus/wilt?

I noticed the neighbors on both sides had brown/dead areas in their maples last year, which I know is typical of wilt, but overall their trees looked healthier than ours. Our tree has also come back where theirs are still bare??

Thanks again :)
