Rental Property Calculator Questions

[Shawn Speelman]

I'm evaluating my first potential income property. I have a few questions about the percentages most of you use? Specifically- repairs, capital expenditures, property management. 

Also future assumptions- Income, Property Value and Expense Increases.

I understand that every market is different but until I gain experience and would like to put some sort of value for now. Its a triplex in Yuba City, CA

Thanks.
