This is the heart of the reason housing isn't mroe affordable, that landlords bear these types of costs every day.You could probably find cheaper labor, especially to haul away the junk, but not easily as an out of state investor. 

A great deal will easily sell itself. 

As soon as a tenant fails to pay rent, you can file a complaint without waiting 30 days or issuing a separate notice (unless your lease requires one).That being said, it could be a waste of time/fees to run to court because tenants in NJ may come even on rent (even after you win the eviction case) and then they won't be evicted: “The tenant shall have three business days after service of the warrant for removal to pay all rent due.”

But where you will win in MA is appreciation.

Congrats on the wins @Jarrod Ochsenbein!

so you can easily do some background on the principals..

There are easily 5-6 meetings per week you can go to and learn from people who have been in this business for decades.

Are you able to reduce your expenses quickly and easily if needed?
