Hi Andrea,
It sounds like for this property there is a cost associated with connecting the home to the public sewer system (assumably from a private septic) and that the seller is not willing to pay this cost. This type of disclosure is more commonly seen in a seller's market. These days I'm seeing sellers "assume betterments" for buyers that in a different market would be unheard of. It may be up for negotiation if they truly want to sell.

Good luck! Hope that helps.

I can't be exactly sure...it depends where the sewer issue is. It could be that the development you are interested in has had sewer issues and they are passing the repair &/or replacement charges along to the residents or it could mean the town is putting in public sewer and they are passing along the cost to residents...or some other reason. In any event, if you purchase this property, "assume sewer betterment fees" means you will be responsible for those fees. They could be yearly or even monthly fees. You need to investigate to find out exactly what's involved and what the total cost is going to be and for how long. Are you working with a Realtor?

Sewer betterment is a fee charged to upgrade sewer service to a particular street, local or entire town.
The fees can be substantial, can be a one-time occurrence or stretched over multiple years, so it is important to fully understand the implications. "Buyer to assume sewer betterment" means that the current owners are not intending to pay for the sewer upgrade as part of the marketing

Andrea,
A sewer betterment assessment is a tax that can be assessed by municipalities to properties that have been "bettered" by the construction of a public sewer. Service by a public sewer is an improvement over on-site wastewater disposal (i.e. septic systems, etc.). Therefore, when a municipality constructs public sewers, the value of those properties abutting the sewer line are said to have been improved or "bettered".
Hope this helps.
