Timing of Renting 3 Townhomes

[Loren Buchanan]

Hello- 

First time poster here but pretty avid reader of the forums and looking for some feedback on renting out some townhomes.  I'm jumping into my first multi-unit townhouse property with 3 total units and we are going to manage ourselves for various reasons. 

My main question is for maximizing rent, does it matter if we release all 3 units on the rental market at once or do we stagger them so we don't flood the market? We are in Seattle and the rental market is extremely strong; our other single townhome rented out the day it was listed. 

My guess is that it doesn't really matter but am curious on others experience with the rental psychology. 

Thanks!

Loren
