Is a lease binding if I never moved in?

Yes. The lease became a binding contract when both parties signed it, and your obligations started on the lease start date whether or not you ever picked up the keys. Not moving in does not void it or convert it into an offer you declined. Legally, walking away is breaking a lease, with the same framework for what you owe.

Do I owe the full year of rent?

Rarely. In most states the landlord has a duty to mitigate damages, which means making reasonable efforts to re-rent the unit. You are on the hook for rent while it sits vacant despite those efforts, plus reasonable re-rental costs like advertising, and any difference if it re-rents for less. Once a replacement tenant starts paying, your obligation generally ends.

Can I just lose the deposit and walk away?

Sometimes, and it is a common negotiated outcome, but it is not automatic. The deposit is security for what you owe, not a pre-agreed exit price, so a landlord with a longer vacancy can pursue more. Some leases include an early termination or buyout clause with a set fee; if yours does, that clause is usually your cleanest path.

What is the best thing to do if I know I will not move in?

Tell the landlord immediately, in writing, before the start date if possible. Early notice gives them maximum time to re-rent, which directly shrinks what you can be charged. Then negotiate: offer the deposit or a fixed buyout in exchange for a signed mutual release. Silence is the expensive option, because the clock runs while nobody is marketing the unit.

Will backing out of a lease hurt my credit or rental history?

It can if it ends badly. An unpaid balance can go to collections and surface on credit reports and tenant screening for years, and the landlord can sue in small claims. A negotiated, documented exit with a mutual release avoids all of that, which is a big part of why negotiating beats disappearing.

You Signed a Lease but Never Moved In: Are You Still on the Hook?

The job fell through, the relationship ended, or a better place opened up, and now there is a signed lease for an apartment you will never live in. The instinct is to assume that no keys and no boxes means no deal. The law sees it differently: the contract formed at signing, and what you do in the next few days decides whether this costs you a deposit or a judgment.

The lease bound you at signing

A lease is a contract, and contracts take effect when signed, not when performed. The landlord promised you possession starting on a date; you promised rent for a term. Never collecting the keys does not unwind those promises any more than never picking up a special-order couch unwinds the purchase. So the question is not whether you are obligated. It is how much of the obligation you will actually end up paying, and that number is far more negotiable than people expect.

What you actually owe

Not, in most cases, the whole term. The realistic components:

Rent while the unit is vacant, starting from the lease start date, until a replacement tenant begins paying.
Reasonable re-rental costs, such as advertising or a prorated leasing fee, where state law and the lease allow.
Any shortfall if the unit re-rents for less than your rate, for the remainder of your term.
An early-termination fee instead of all of the above, if your lease contains a buyout clause and you use it.

The duty to mitigate is your leverage

Most states require a landlord to make reasonable efforts to re-rent rather than letting the unit sit empty and sending you the bill. A landlord who does nothing for four months and then demands four months of rent has a weak claim in most of the country. This duty is why speed matters so much on your side: the sooner they know, the sooner marketing starts, and the shorter the vacancy you can be charged for. The mechanics mirror an ordinary early exit, covered in breaking a lease early.

The playbook, in order

Notify the landlord in writing today. Email is fine. State plainly that you will not be taking possession and that you want to resolve it.
Read your lease for an early-termination or buyout clause. If one exists, invoking it is usually cheaper and cleaner than open-ended liability.
Offer a concrete deal: commonly the deposit plus a set amount, in exchange for a signed mutual release ending all claims.
Help the re-rental if you can. A referred replacement tenant who signs ends your exposure outright.
Get the release in writing before treating it as over. A verbal we will figure it out is how collections letters happen a year later.

What the landlord cannot do

Even in this situation the rules hold: the landlord cannot keep the deposit and simultaneously collect full rent for a unit they promptly re-rented, cannot skip the state's deposit accounting deadlines, and cannot double-collect rent from you and a replacement tenant for the same weeks. If the numbers they demand ignore a quick re-rental, that is the dispute to raise, in writing. See what a landlord cannot do.

For landlords holding a no-show lease

Document the tenant's notice, start marketing immediately and keep records of the effort, and account for the deposit within your state deadline. A clean mitigation record is what makes your claim collectible; a dark unit and a demand letter is what loses in small claims. A lease with a clear early-termination clause turns the whole event into arithmetic. See documenting lease changes.
