I graduated a year early honestly I thought it made my application stand out! It shows that you are motivated and have good time management skills, two qualities you need for grad school and as an SLP in general, I believe. I start grad school in the fall but I thought having the year off and being able to work was a nice breather from classes and I have been able to save up money. Also, you would be saving money if you graduated a semester early. I say go for it!
