New Investor, need some advice

I am about to sell my personal home, a foreclosure I bought two years ago, for a nice profit. I want to buy some rental properties and I would like to buy another undervalued home to live in and flip again in a few years. My question is what is the best way to get started? If I buy a rental now(there are two I like the numbers on) will it make it harder to finance my personal home? Or, if instead I buy a primary residence that takes up most of my available income will I still be able to finance a rental house in a month or two? I have good credit and 20% down on rental and primary but I'm concerned about the timing. Would it be smarter for me to buy a less expensive primary until I can show a steady income on my rentals? I was ready to jump in until I started thinking about the timing of all of this but I suppose there is always a reason to hold off on taking a risk. I'm ready to jump but I could use some advice on which way to go! Thanks!
