Septic Experience? Should it scare me off?

[Lyle Silverman]

What's everyone's experience with septic tanks? Just curious as I have no experience with them at all and it hasn't scared me away yet from a 3 unit property that I just put an offer on.

My main takeaways:

Need strict rules in lease about what can be used for toilet paper, laundry frequency, waste/chemicals going into the sink.

300-800 maintenance every couple years for pumping/inspection

Expect five-figure costs if you have major repairs or replacement.

Anything else I should be looking out for?

Thanks in advance!
