Buying a second multi family property

[Miguel A Calderon Jr]

Hello Everyone,

I am new on the Bigger Pockets forum and I am looking for opinions/advice from experienced real estate investors on how should I go about buying my second property. First, let me give you a rundown on my situation. Back in 2014, I purchased a multifamily that was flip for 317K, I put in 40k into the house (finish basement, central air and heating. Fast forward to 2016, I recently refinance to a conventional loan because the property was appraised for 375k which eliminated my PMI. Now, I am looking to buy my next multi family property within the next 10 months or so, my question is was the best way of economically buying my second property?

1) Buy the property under an FHA loan put down 3.5% ,live there and refinance down the road? (kind of leaning towards this)

2) Should I save up 20% for downpayment and the stay where I currently live because I am making a profit? 

3) Are there ways of buying a second property for investment purpose without putting money down? (Any small banks in NJ that do 100% financing?) 

Thanks,

Miguel
