A lot of people don't use their formal dining rooms for its purpose, especially, if it has a large eat in kitchen.

Between time eating, working out, and commuting you’d be surprised how many books you can get through in a year.As far as getting started investing, I would focus on networking in school, get involved, get a good GPA, and find a way to start making money.

Also more specifically, Cleveland seems to be great for cash flow, but I have heard required inspections from the city can be incredibly frustrating, eating up time and money.

Also military communities are really difficult sometimes because if you miss matching a tenant vacating to the summer or winter manning cycles that people PCS on you could be in for eating a few months on the rent before the property gets filled.

In regards to @Allan Szlafrok point, taxes are high in essex county, so it can definitely eat into the cash flow for buy and hold investments.

No excuse to not pay you , dont they have money for cigarettes cell phones alcohol eating out dog food etc .. geez it’s only been a a couple weeks and they are already planning to stiff you ? 

Be careful putting all your eggs in one basket.

Taxes, Insurance, Property Management, Vacancy, repairs, capital expenditures, will all eat away at your cash flow.

Going to see unmotivated time wasters will eat away at your spirit if you are new to the game.

As well, if an out of state investment goes sideways, a few flights to visit a smaller property can eat up all your annual rental profits.
