Seeking Advice On Septic Systems

[Simon Wold]

Hey-

So I am looking at putting an offer on an 8 unit apartment building in the Seattle, WA area.  My only hesitation is that the building is on septic... does anyone have experience with multifamily septic systems?  What kind of maintenance cost are associated with being on septic?

Should this be a big concern for me? I feel like it can lead to problems down the road.
