How to estimate variable expenses for deal analysis? (Orlando)

[Amie Lamb]

I am wondering if any of you would share the numbers YOU use for estimating repairs, vacancy, capex and PM? I have used the BP calculators and things I have learned in the podcasts to come up with my own deal analysis spreadsheet. This would be for an initial analysis of the property before really viewing it or gathering house specific data. 

I am thinking that these percentages may be off (hoping they are high...). Would love to hear what you use to estimate variable costs in your own deals.

Percentage of rent:

Repairs: 15%  (Targeting an area with older homes at this time)

Vacancy: 10% 

Capex: 15%

PM: 12% (I will be doing my own PM but want to build this in so I have the option in the future)
