CapEx Savings Account?

[Aaron Currier]

I currently own 2 positive cash flowing duplexes and intend to grow my portfolio over the next 20 years or so. While analyzing a property for purchase, I allocate %5 of gross rents for capital expenditures. On my most recent acquisition this is about $68 a month. Do you recommend that money staying in the general business checking account or do you bump that money each month to a CapEx savings account to build up a fund for future capital expenditures?
