A First-Time Buyer's Guide to Reading a Purchase Agreement

TL;DR: A purchase agreement is the legally binding contract between buyer and seller that fixes the price, earnest money terms, contingencies, and closing date. Once both parties sign, you're on the hook for the terms as written, so read the financing, inspection, and appraisal contingency language before you sign, not after. If you're buying a rental, the purchase agreement also sets the cost basis you'll depreciate for years, so keep every page.

You're staring at a 15-page contract full of dense clauses, and the seller wants an answer by tomorrow. That pressure is normal, but signing something you haven't fully read is how first-time buyers end up losing earnest money or stuck with a property that has problems they never checked for.

Okoniq Property Hub helps you keep the signed agreement, addenda, and closing disclosure in one place so you can pull the right page months later when a tax question or repair dispute comes up.

What exactly is a purchase agreement, and why does every line matter?

A purchase agreement is the contract that turns a verbal offer into a legal obligation. It states the purchase price, who pays which closing costs, what's included in the sale (appliances, fixtures, sometimes furniture), the closing date, and the conditions under which either side can walk away without penalty.

Once both parties sign, the terms are enforceable. If you miss a contingency deadline written into the contract, you can lose your earnest money deposit even if you had a legitimate reason to back out. That's why the document deserves a full read, not a skim of the highlighted fields your agent points to. If you're buying with plans to rent the property out, this contract is also the starting point for your future recordkeeping — a chart of accounts for landlords begins with the numbers on this page, not the numbers you remember later.

What money terms do you need to check before signing?

The money terms in a purchase agreement are the purchase price, the earnest money deposit, who pays which closing costs, and any seller credits or concessions. Each of these should be spelled out in exact dollar figures or exact percentages tied to the final sale price, not left vague.

Pay close attention to how the earnest money is described: how much is due, when it's due, and under what circumstances it's refundable versus forfeited. Also check whether the seller is crediting you money toward closing costs or repairs, and confirm that credit shows up again on your closing disclosure at settlement. Numbers that appear in the purchase agreement but vanish from the closing paperwork are a red flag worth raising with your agent or attorney before you sign anything at the closing table.

What contingencies actually protect you if something goes wrong?

Contingencies are the clauses that let you cancel the contract and get your earnest money back if specific conditions aren't met. The three most common are the financing contingency, the inspection contingency, and the appraisal contingency.

The financing contingency protects you if your loan falls through. The inspection contingency lets you renegotiate or walk away if a professional inspection turns up problems. The appraisal contingency protects you if the home appraises for less than the agreed price. Every contingency in the agreement has a deadline attached, and missing that deadline can waive the protection entirely, even if you didn't realize the clock was running. Read the dates, not just the clause titles.

| Contingency | Protects you against | What happens if waived | |---|---|---| | Financing | Loan denial or delay | Risk losing earnest money if financing falls through | | Inspection | Undisclosed defects | No renegotiation leverage after signing | | Appraisal | Low valuation vs. price | Must cover the gap in cash or renegotiate before this clause exists |

What tax and basis details start the moment you sign?

The purchase agreement is where your cost basis begins, and cost basis determines how much you can depreciate and how much gain you'll owe tax on when you sell. The price, allocated land-versus-building split, and any closing costs that get added to basis all trace back to the numbers on this contract and the closing disclosure that follows it.

If you're buying a rental, some of what you spend right after closing may qualify for immediate expensing instead of being depreciated over years. The de minimis safe harbor lets landlords expense items costing $2,500 or less per invoice or item (without an applicable financial statement), which covers plenty of the appliances and fixtures you might replace right after taking possession. Separately, qualifying property placed in service after January 19, 2025 may be eligible for 100% bonus depreciation under current law, a significant change from the phase-down schedule many buyers still assume applies — confirm the current rules before you file, since bonus depreciation rules changed more than once in recent years. If the property is large enough to justify it, a cost segregation study can also break out components of the building for faster depreciation, but that decision starts with an accurate purchase price allocation in the contract itself.

What should you do in the days before closing?

In the days before closing, compare every number on your closing disclosure against the purchase agreement, and don't sign the final paperwork until the two match. Confirm the closing date hasn't shifted without a signed addendum, verify that repair credits or seller concessions from the contract actually appear as line items, and keep a copy of every addendum, not just the original agreement.

If your property tax bill on the listing looks off relative to the assessed value, this is also the point to start researching whether you'd have grounds to appeal the property tax assessment after you take title. And if you're converting the purchase into a rental rather than living in it first, the tax treatment differs in ways worth understanding before you close, covered in more detail in how converting a primary home into a rental affects your basis and depreciation start date.

FAQ

Is a purchase agreement the same as a closing disclosure?

No. The purchase agreement is the contract you sign when your offer is accepted, setting price and contingencies. The closing disclosure is a separate document you receive shortly before settlement that itemizes the actual costs and credits at closing.

Can I back out of a purchase agreement after signing?

Only within the terms the contract allows, typically through a contingency deadline for financing, inspection, or appraisal. Backing out after those deadlines pass, or for reasons not covered by a contingency, usually risks forfeiting your earnest money deposit.

Does the purchase agreement affect my taxes later?

Yes. The price and allocation in the purchase agreement, plus qualifying closing costs, establish your cost basis, which drives your depreciation deductions each year and your taxable gain when you eventually sell.

What's the difference between a contingency and an addendum?

A contingency is a condition built into the original agreement that lets you cancel under specific circumstances. An addendum is a separate document that amends or adds terms to the agreement after the fact, and it needs to be signed by both parties to be enforceable.

Should I keep the purchase agreement after closing?

Yes, permanently, along with every addendum and the closing disclosure. These documents support your cost basis calculation and can matter years later if you're ever asked to show your audit trail for the property.
