Buying investmentry rental properties

[Kunal Mishra]

Hello All,

I own two investment properties (each with two units) in Jersey City, both on a personal loan on my name. 

How can I start buying more properties and grow my portfolio , offcourse just on my income I cannot get loans on 10 properties not even if I include my wife's income. 

Hard Money Lenders are good for flips and will be very expensive.

Do I have to look for portfolio lenders in NJ, How much is the approximate interest rate that they charge.

Thanks
