non-conventional duplex calculation

[Monica Litster]

I am working on a non-conventional duplex. Monthly income is $2300. I typically set aside 10% for each vacancy, prop mgmt, and repairs/cap ex. What would be more reasonable amounts to use?

The one side, the largest amount of rent is subsidized, so auto deposit, and the other side is prompt on the 1st every month. Should I go a lower %age on these categories, or  stay with the usual 10%?

Thank you!
