I plan to refinance the property at the 6 month mark into a 30 year fixed mortgage and I was wondering what types of improvements boost the appraisal the most. 

Why on Earth would a stranger give you that deal, mark it up an make a better profit. 

@Mark H.A 401(k) is an employer sponsored plan. 

My father in law is a plumber in the area and he is marking up most of the new construction jobs he's doing by at least 20% because he is so busy.

And if the rent is around that 4400 mark, and you're putting 100k into...

@Mark AndrewsYou are required to first allocate the purchase price to land and the building.The amount allocated to land is non-depreciableThe amount allocated to building is depreciableYou may also make improvements to the property which can possibly be added to the basis(if not expensed). 

@Mark Gee - I've noticed the reduction in rent prices at Hoboken as well, and it seems like the rentals do not get snatched up as quickly as they used to anymore.

@Mark Anderson don't be so quick to give away the farm!
