Opendoor Preliminary Offer vs Final Offer: What Actually Changes

How Opendoor Builds the Preliminary Number

The first number comes from a machine, not a person. Opendoor's automated valuation model has been trained on hundreds of thousands of transactions since 2014, weighted toward comps from the past few months. It pulls county records: assessed value, ownership history, tax obligations. It pulls neighborhood comps, square footage, bed and bath count, lot size, year built, ZIP-level market trends, and whatever condition and upgrades you reported yourself.

Then comes the part most sellers miss: risk adjustment. Opendoor is not just pricing what your home is worth today. It is pricing what could change between the day it makes the offer and the day it resells the house: inventory levels, interest rates, seasonal shifts, its own holding and resale costs. All of that gets baked into the preliminary number before anyone sets foot on the property.

What Changes Between Preliminary and Final

The final offer follows a home assessment: either a self-assessment through Opendoor's app or an in-person walkthrough, depending on your market. That assessment covers structural integrity, major systems like HVAC, plumbing, and electrical, interior and exterior condition, and code and safety issues. Opendoor then estimates repair costs and deducts them from the offer as its own "Estimated repairs" line item. You do not hire contractors. You do not manage the work. Opendoor handles repairs after closing.

If the house matches or beats what you described, the offer can hold steady or even go up. The most common seller mistake, according to Opendoor's own guidance: downplaying condition on the initial questionnaire. The assessment catches the issues anyway, and the downward adjustment lands harder than if you had just reported them upfront.

Two more things matter before you compare your net. Opendoor does not publish a fixed service-charge percentage: the rate varies by market and by home. And the net proceeds math subtracts the service charge, estimated standard costs, and estimated repairs from the offer price, so the headline number is not what you actually walk away with.

The Trade Opendoor Names, and the Route That Skips It

Opendoor's own article says its number "trades some of that potential upside for speed, certainty, and simplicity." Translation: your offer can land below what an open-market sale would bring. That is not a knock on Opendoor. It is how the model has to work: it prices in resale risk and repair costs before you sign anything. You may decide that trade is worth it.

With Cash Flow Deals, you have two offers to compare: the Fast Cash Offer, where we buy your house as-is and close, and the Premium Cash Offer, where a pre-approved FHA or conventional buyer we already have, ready to go, pays more and buys directly from you. You choose. If your home is in Florida and you are weighing a model-driven number against a sale to a real buyer, start at our Florida hub: /florida/sell-my-house-fast.

Here is how you move from comparing offers to closing with Cash Flow Deals.

1. You share your property details and compare the Fast Cash Offer and the Premium Cash Offer. The number is agreed before any work starts, and it changes only if you agree. The one exception: if something structural surfaces that was not visible or disclosed before we signed — foundation issues, hidden moisture, old wiring, cast-iron drain failure — we re-cost it and bring the number back to you. You decide. You can walk away. We disclose what we know at offer time so this almost never happens.

2. If you choose Premium, you sign with us at the agreed number and give us permission to bring a buyer in our place. Your home may be listed through Silver Door Realty, a licensed Florida brokerage, with a licensed agent and scheduled showings. The buyer signs a new contract directly with you, title transfers directly from you to that buyer, and their lender funds the purchase. We cover repair costs, and we figure out a way, so nothing comes out of your pocket. Only what the buyer's lender requires gets fixed, with costs settled from the sale proceeds from our share. With Fast Cash, we buy as-is and you make no repairs. We are paid as a separate line item on the Premium closing statement.

3. Closing moves in 45 days or less, on a date you help pick. If your Premium buyer's loan falls through, that is our problem, not yours. You can still choose the Fast Cash Offer at its own number alongside the Premium Cash Offer.
