You don't need to save up $100K or quit your job today in order to become a successful investor. 

That is my day job.

I'm doing quite a bit myself but the cast iron part is a job bigger than I can handle.Any recommendaitons for rough-in plumbers in NJ and willing to travel about 15 miles outside of Newark?

No one checks the maintenance crew to see if the did a good job (as far as I can tell, their in house folks miss stuff). 

Can they be more passive than having a 9-5 job?

A client of mine recently invested there and raves aboutt the ease of finding solid contractors who stick to the budget.One piece of advice: before jumping into any market, spend time understanding the local economy, demand drivers (like job growth and population trends), and the landloard laws.

Also, focus on 2 years of job/income stability.Class D Properties:Cashflow vs Appreciation: Typically, all cashflow with little, maybe even negative, relative rent & value appreciationVacancy Est: 20%+ should be used to cover nonpayment, evictions & damages.Tenant Pool: majority will have FICO scores under 560 (almost 30% probability of default), little to no good tradelines, lots of collections & chargeoffs, recent evictions.

U live a lifestyle not a job huge difference..

STR it will cost you big.this isn't a difficult job depending on the fridge location.
