Washington primarily uses which security instrument?

Washington does not primarily use mortgages. Mortgages create a direct lien between borrower and lender and typically require judicial foreclosure, which is less common in Washington than the non-judicial foreclosure process available with deeds of trust.

Land contracts are not the primary security instrument in Washington. They are installment contracts where the seller retains title until full payment, not the standard security instrument for real estate loans.

Security agreements are used for personal property, not real estate. They govern collateral for business loans and don't apply to real property transactions in Washington.
