It's a fairly long ride, as was noted below. There are a lot of communities along the beach closer to MU that you can look at....lots of development in Long Branch (check out Pier Village for great shops, restaurants and rentals overlooking the ocean). Asbury Park has some really good values, too, as far as new and renovated condos are concerned. You will have many options a lot closer to the university...LBI (Long Beach Island, where beach haven is located) is great, but far.
I don't handle those areas, but I am an old "shore gal", having spent many summers growing up along the Jersey shore.
My friends did just what you want to do......they bought their daughters a condo not far from the university to live in when they attended school. They just sold it this past year, after both girls graduated.
Look around with an agent in the various areas surrounding the school - you will find something.
Good luck to your son!

The ride should be pretty easy in the off season. It will depend on his class load and schedule. I would think he isn't going to run home for lunch.
