Cash For Houses: How The Offer Number Actually Gets Built

A cash-for-houses number is comps minus a repair estimate minus a margin, and it lands below full market value. That's on purpose. Cash Flow Deals is one of the real options that builds a Florida seller's number this way, alongside iBuyers and other cash-buying investors, and each uses a different formula. Home sales closing without a mortgage hit 39.1% of the U.S. total in 2025, the highest share since 2013, according to ATTOM Data Solutions, so this math now touches four in ten sellers, not a fringe few. Know the three numbers behind the formula, and you can tell a fair number from a lowball one before you ever sign.
| Cash Flow Deals | Traditional Listing | |
|---|---|---|
| How The Number Gets Built | Locked from real comps before any repair estimate exists. Discount is priced in once, never renegotiated after signing. | List price set by comps, then tested, and often cut, by buyer offers, inspection credits, and a low appraisal. |
| Timeline To Close | As little as 10 business days once the number is set. | 85 to 100 days from list to close, per Opendoor's own published cash-vs-traditional timeline breakdown. |
| Repairs | None required. Repair estimate is subtracted once, up front, never reopened after signing. | Buyer-requested repairs or credits after inspection can cut into your net a second time. |
| Fees | One flat fee, disclosed before you sign. | About 5.70% total agent commission on average, split between the listing and buyer's agents, per Clever Real Estate's survey, plus typical seller closing costs. |
The Three Numbers Behind Your Cash-For-Houses Number
So why does the exact same house get a lower number from a cash buyer than a financed buyer would pay for it? Three numbers build that gap, and none of them is a mystery.
The first number is the comp baseline: recent, closed sales of similar houses nearby, the same data a listing agent would pull for a market analysis. The second number is the repair estimate, a dollar figure subtracted for whatever the house needs before it could resell at retail, whether that is a new roof or fresh paint. The third number is the buyer's margin, the amount a company needs to keep as its return for taking on the house as-is, funding it, and carrying the risk until it resells or rents.
Stack all three and you get the number in your hand: comps, minus the repair estimate, minus the margin. You can ask any real cash buyer for those three inputs individually. A company that will not break out the math for you is usually hiding one of the three, and it is almost always the margin.
Why That Number Sits Below Retail, On Purpose
A cash-for-houses number is not a lowball attempt. It is the visible price of trading market-value uncertainty for a locked number and a fast close.
A traditional listing chases the highest possible price through showings, multiple offers, and negotiation, and it pays for that upside with time and risk: a buyer's financing can fall through, an appraisal can come in low, or an inspection can reopen the price after you have already mentally moved out. A cash-for-houses number skips that whole process. You are not paying a fee on top of your sale so much as trading the top slice of retail value for certainty that the number will not move and the closing date will hold.
That trade is not automatically bad for you. It is a bad trade only when a seller does not know they are making it, or when the discount is bigger than the risk it is actually buying off.
How Big The Gap Really Is, By Buyer Type
Not every cash buyer prices a house the same way, and the gap between them is bigger than most sellers expect.
Franchise buy-and-resell companies, the type with a sign in the yard, generally price at 50% to 70% of fair market value, a range Opendoor itself publishes when explaining how that business model works: the discount funds the repairs, the holding costs, and the resale profit the company needs after it takes ownership. iBuyers like Opendoor price closer to market value instead, pulling more than 100 comparable sales per ZIP code and disclosing a separate service fee rather than folding a bigger discount into the number itself. Cash Flow Deals sits in a third lane: a Florida real estate investor that locks the net price from comps before a repair estimate exists, arranged through a licensed local broker partner instead of built on a resale margin the way a franchise buyer's number is.
Ask which lane a company is in before you compare two numbers side by side. A 70%-of-value number from a franchise buyer and a near-market number with a disclosed fee from an iBuyer are not the same math, even when the two final dollar figures happen to land close together.
How Cash Flow Deals Builds Your Number In Florida
Florida sellers deal with one factor most cash-for-houses explainers skip: who actually holds the license that makes the closing legal, and what happens if something the number was based on turns out to be wrong.
Cash Flow Deals is a Florida real estate investor that locks in a net price for a seller's house before repairs are scoped, using a novation-based, flat-fee process arranged through its licensed FL brokerage partner, Silver Door Realty - not a traditional listing, and not a brokerage itself.
The process runs in three steps. Step 1: Cash Flow Deals reviews the house and builds your number from real comps, before any repair estimate exists. Step 2: the house gets a walkthrough, and a repair estimate and margin get applied once, not renegotiated later. Step 3: Silver Door Realty, the licensed FL brokerage partner, handles the paperwork that connects the house to a real end buyer, and the deal closes on the timeline you set, often in as little as 10 business days.
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.
Common questions
Why is a cash-for-houses number lower than market value?
Because it is priced for certainty instead of maximum price. A cash-for-houses number starts with comps, subtracts a repair estimate, and subtracts a margin for the buyer taking on the house as-is and carrying the risk until it resells. That discount buys you a fast, certain close instead of weeks of showings and a buyer's financing that could fall through.
How does a cash-for-houses number actually get calculated?
Three inputs: the comp baseline from recent nearby sales, a repair estimate for what the house needs before it could resell at retail, and the buyer's margin for taking on the risk. Cash Flow Deals locks that number from comps before a repair estimate exists, then applies the repair math once instead of renegotiating it after you have already signed.
Do all cash-for-houses buyers price a house the same way?
No. Franchise buy-and-resell companies typically price at 50% to 70% of fair market value, a range Opendoor's own materials use to explain that business model, because the discount funds repairs, holding costs, and profit after they take ownership. iBuyers price closer to market value and disclose a separate fee instead. Ask which model a company uses before you compare two numbers.
How many home sales close without a mortgage now?
39.1% of U.S. home sales closed without a mortgage in 2025, the highest share since 2013, according to ATTOM Data Solutions. Separately, the National Association of Realtors found cash made up 26% of primary-residence purchases in 2025, an all-time high in its own survey. Either way, this is a mainstream path now, not a rare one.
