Washington and Bellingham Real Estate Terms Buyers and Sellers Should Know
NWMLS (Northwest Multiple Listing Service)
NWMLS is the regional multiple listing service used by licensed real estate agents throughout Bellingham, Whatcom County, Skagit County, and much of Washington State to list, search, and track homes for sale.
Form 17 Seller Disclosure
Form 17 is Washington State’s standard seller disclosure statement.
This document explains what the seller knows about the property, including roof history, plumbing, electrical systems, water intrusion, environmental concerns, boundary disputes, structural issues, and known defects.
Mutual Acceptance
Mutual acceptance is the exact moment buyer and seller have agreed to all contract terms in writing and both parties have signed.
In Washington real estate, this creates the binding contract.
Earnest Money
Earnest money is a good faith deposit submitted with an offer to show the seller the buyer is serious.
In competitive Bellingham markets, stronger earnest money can improve offer positioning.
Escalation Addendum
An escalation addendum allows a buyer to automatically increase their offer if competing offers are received, up to a defined maximum.
This is commonly used in competitive markets.
Inspection Contingency
An inspection contingency gives the buyer time to inspect the property, review findings, negotiate repairs, request credits, or terminate the agreement.
Financing Contingency
A financing contingency protects the buyer if mortgage approval cannot be finalized.
Appraisal Contingency
An appraisal contingency protects the buyer if the lender’s appraised value comes in below the contract price.
Counteroffer
A counteroffer changes the terms of the original offer and requires acceptance by the other party.
Seller Credit
A seller credit is money the seller agrees to contribute toward the buyer’s closing costs, prepaid expenses, or negotiated repairs.
Closing Disclosure
The lender’s final loan summary showing monthly payments, closing costs, loan terms, and cash required to close.
Title Insurance
Title insurance protects buyers and lenders from ownership disputes, liens, recording errors, legal claims, or title defects.
Recording
Recording is the official filing of ownership documents with the Whatcom County Auditor, transferring ownership to the buyer.
Possession Date
The possession date is when the buyer receives access to the property.
This may happen on closing day or later depending on contract terms.

Buyers should verify access and transfer rights.
Easement
An easement grants another party legal access across or through part of a property for utilities, roads, drainage, or access.
HOA (Homeowners Association)
