New Investor, am I building too fast

[Sarah Schneider]

Hello Everyone,

My name is Sarah, I purchased my first property this July in Onslow county, North Carolina. I have an itch to keep going but I hesitate wondering if I’m moving too fast.  I had savings to put a large down payment down on my first one and for my second one I still have some savings to use and can also use equity from my first house. Although I have income, a big fear is getting too many loans, (the crazy thought of loosing my job, can’t get tenants) and then can’t make all my payments. I could use some encouraging words or realistic grounding. 
thank you in advance!
