Vacancy & Ongoing CapEx

[Robert Meagher]

Hey team,

I'm 26 y/o and very new to RE investing. I'm exploring the possibility of house-hacking in the Chicago area. I have a Property Analysis spreadsheet that was shared with me by a friend. As I evaluate different options here, I wanted to ask - what are fair vacancy and ongoing capex rates to account for in my analysis? 

I currently have 8% for vacancy and 5% for ongoing capex. Are these fair estimates?

Similarly, if anyone is open to connecting with a stranger, I'd love the opportunity to hear from someone who's already house-hacked a property in the area and hear their story (and advice). 

Thanks!
