Septic replacement costs

[Josh Longtin]

I found my first flip property. Will likely need a ton of elbow grease and some cosmetics, but I love the deal. Love it.

Will require a 3 bedroom septic system. (Home is 1150 sq ft.) Anything I have ever heard or been told, I am safely looking at 25-30k for septic install. (Property has a cesspool now which needs to be changed over to septic, so its a start to finish install)

Someone just sent me 2 articles (one of which from zillow) claiming that from design to install, a new septic should cost you between 4-8k.

Thats quite a big difference.

I initially planned to budget on the 30k as it still leaves plenty of meat on the bone for my plan. Anyone have any first hand experience with this before I hire a guy to come survey the lot??

Help! And Thanks!!
