Did most of the renovation myself except for a new furnace/ac/chimney liner as well as an upgraded 100 amp electrical service/meter/offset riser which were done by the hvac and electrical contractor I use.In the 4 years I've owned this home I have only had to snake the main drain 2x.

Then have it snaked clean.  

@Joseph Duenas I am talking from experience here:the snake is the grass is not so much what the local bank thinks but rather what the Business line credit does to you.

Not to mention I'm not a fan of giant snakes and alligators.

Contrary to what your plumber freind said, a see snake can give you a very good idea of what the condition of your underground waste pipes are in. 

Your inspection is what matters.Most likely you just need a pipe snaked out.

I remember a Zombie show where they had all these snakes in the house that came in overnight.
