Im very optomistic but what happens if the home doesnt lease out?

[Joshua Brewer]

My fiance and I are wanting to get started in the real estate business, but our main concern is what if the first property we buy doesn't rent out for a few months. We both work full time jobs, but we are also not wealthy. our concern is what if the property that we get goes months without making cash flow and we are stuck paying the mortgage on the home and we don't have enough saved up. Do we purchase the home and take out extra loan for a  "just in case fund"? and if we do that then we are having to pay back that loan that could effect the cash flow. I do not want FEAR to take control of my future. but i don't want to be stuck paying another mortgage that we cant afford right now. any advice?
