First single family home rental, how to plan for vacancy?

[Nick Delfin]

Hi everyone! I am new to bigger pockets and I a looking for some advice.

I am looking to purchase my first single family home coming in 2020. I am looking to buy a home around 150k and rent it out.

My biggest fear is having long term vacancy.

I would have the money to pay for the mortgage when nobody is renting, however, I am planning on buying multiple homes in the future and then that won't be an option.

How does one overcome this fear and plan for it?

Any advice helps.

Thanks,

Nick
