Nice yard and garden to have acquired!! It seems like you must have put in quite a bit of work this summer edging and mulching and trimming since you mentioned that it was neglected when you purchased it, but it looks well cared for now.

It has been in my care for three weeks now. I have put in some work, but can't claim any beauty yet. I maybe misspoke when said neglected, it's overgrown in some areas, and over pruned in others. I think its a bit overwhelming when I think of the scope of work that needs to be done, but I'm taking it one day at a time. There is quite alot in the front (cut back now) that needs to be split. And some things that look squished, but it's beautiful and I can't wait to see spring bloom.

They did in fact enlist a landscaping company. Will I need to re edge every year?

More like every time you mow the lawn. At least the grass will need edging. (Google edging shears). The actual soil edge may not need doing much at all if the grass is done regularly.

I did a test spot, and it seems that they simply mulched over grass, I got almost 4 inches out, so I will be busy in the spring I think.
