Vacancy rate for out of state investing 30%?

[Jarrod Gregory]

I am reaching out to an out of state market. I’ve spoke to a few realtors in the area I’m considering and one who seemed the most knowledgeable said that 10-15% vacancies are the norm but he recommendes out of state investors should make their plans based on double that number so 20-30%. Seems way high to me. What are your thoughts. Btw I’m targeting B class neighborhoods. Thanks
