Buying second home - rental

[Drew Slew]

I am in almost exactly same situation as @Richard Donofrio .

I just bought my first 1br condo (layout makes it 2br so rented 1 room), near NYC in Union City about 3 months ago. 
HOME - 

150k listed, bought for 145k, appraised for 148k. I put 30k down, 30yr fixed at 3.5%, total monthlies w utilities, HOA, mortgage, electricity, wifi etc TOTAL only 1100/month. I rented 1 room out for 800/month so now i basically live free and want to quickly buy my second home, purely investment purposes - the closer the better, to walk over, check on tenants etc.

INCOME - 

I have income of around 80-90k, also have monthly 550 student loans.

Total i now only have 10k cash, and that 30k equity i put into first home a few months ago. I have a 12k credit card w no interest too for 1 year. Asked about using that too, but thats tricky. I can get 10k as gift money also quick.

EXPENSES - 

So NET income is around 4000-5000/month, debt is 950 total plus food, travel etc living expenses. 10k cash and 30k equity in home. 

Id like to buy something around 100k quick, Union CIty, NJ or even cheaper areas, rent it asap, purely investment. At least $200-300 profit monthly on renting it out, so 1% rule and so on..

Ideas for loans, financing etc? Foreclosed? Or should I wait and save up more as this current living situation is quite ideal (free basically)?

Thanks
