Best Strategy to Grow My Portfolio & Cash Flow

[Tony C.]

Hi,

I am looking for some advice in terms of the financing strategy to grow rental portfolio. Now I have no mortgage debt on my primary house (market value 700K) and  2 investment properties (total market value around 480K), generating 3K gross rental income per month. I have a stable full time job salary and great credit score. If I want to buy more investment properties, hold for 5 to 10 years, and perhaps double my current rental cash flow per month. What are the best way in terms of financing strategy to achieve this? I am in Raleigh-Durham-Cary, NC area, and the local rental market is quite strong and solid.
