@Sharon Patterson, any rehab is a "project" and basic project management principles state that there are 3 key interrelated aspects to all projects: time, scope, and cost.

Thanks for the advice  @Will GastonThis is my first house and I hope to be in real estate for the long haul so Ill take your advice! 

Do i need any license if I start my own property management company in New Jersey to manage my investment properties?

@Josh Cockera house hack isn't supposed to / likely won't cash flow while you live there. 

My goals with BiggerPockets is to learn about real estate investing and network, my wife and I would like to purchase our first house in the next 6 months.

Lists with thousands of records are difficult to manage.

the appraisal should have considered the deficit and wether it was actually one on, like just sold, housing.  

Do you have property management that keeps your money in your pocket?

.)- Ask the neighbors (unfortunately a lot of these houses are in run down areas and the neighbors are transient renters who don't know anything)Pay Sources:- Peoplefinder.com (not too expensive, shows a lot of addresses, married/maiden names, relatives, roommates, etc.

And as a member to an organization that manages well over 10K doors I can say from 1st hand knowledge it would take a LOT of people.
