Typically, the seller signs the closing documents first, before the buyer even arrives at the office where the closing is taking place. Buyers have to sign a LOT more documents than the seller and it is not necessary for the seller to sit and watch the buyer sign their papers.
In most cases, you'll meet with your real estate agent and a title company representative — the seller and their agent don't have to be there. The title company representative will guide you through the process and ensure that all the necessary documents are signed correctly — they take care of the filing.
What is the most important document at closing and why? The deed is the most important document because it transfers the property to the purchaser.
To put it in simple terms, the seller will be responsible for the property tax balance that accrued from the beginning of the tax year until the date of closing, and the buyer will be responsible for property taxes that are due for the period after the closing date. This is a process called proration.
