There are so many factors that influence asset prices that a bad economy or high unemployment may not even drive prices down.

@Michael LoweKeep doing what you are doing and gravitate towards more positive influences.

My guess is somewhere around 25-50 units.Some variables that will influence that are: your distance from the property, the tenant/property class, etc...if you have 1 rental you should probably be self managing.

The purchase price influences that estimate, but the estimate is not set to the purchase price, and the estimate is typically less than fair market value.
