Property analysis

[Anthony Gatt]

Hi, I'm doing property analysis and - like many others - want to account for property management in my numbers. I see a lot of people recommend 10%, to be conservative. However, most PM's charge a full month's rent to place a tenant. In order to protect against this happening a few years in a row, should I be bumping this  up to 15 or 20%? 

Thanks,

Anthony G.
