operating reserves for my first deal in indy

[Jason Malabute]

Hi All,

For my first apartment deal how much should I put aside for  "operating reserves"?

Operating reserves for apartments are insurance, mortgage (principal and interest), and property taxes right?

So Biggerpockets says you should have 6 month of operating reserves, but my mentor says he does 1 month of operating reserves (but he has over 400 units so I think that's why he can do that).What is the right approach for my first apartment?

Thank you
