An iBuyer is a tech company that prices a home with an algorithm and resells it fast. An investor is a person or local company that buys a house directly, usually in any condition, to renovate, rent or resell. If your Knoxville house is move-in ready, an iBuyer is one option to price. If it needs work, has title or tenant complications, belongs to an estate or faces a deadline, a direct investor purchase is built for that. We buy houses and land in Knox County and East Tennessee as-is, so below we show you how the two models differ, how each one arrives at a number, and what to check before you sign.
TL;DR
- iBuyers use automated valuation and property-review systems. A Chase explainer describes service fees of 5% to 6% as typical, but current pricing and adjustment credits vary by company and offer. Use the itemized written terms.
- Some rehab investors work backward from an estimated after-repair value and may consider properties that need work. Eligibility, access, condition and contract terms still vary by buyer and property.
- Both usually offer less than a traditional sale; what you get in return is speed, fewer showings and less prep.
- Before accepting any cash offer, ask for proof of funds, a written contract and a clear closing date, and never pay money up front.
- Our Tennessee cash offer calculator is a quick way to see where a direct offer might land before you talk to anyone.

What an iBuyer actually is
“iBuyer” is short for instant buyer. According to Chase’s overview of iBuying, an iBuyer uses an algorithm to assess your home and makes an all-cash offer, typically within 24 to 48 hours. It then resells the home quickly. The business depends on volume: lots of similar, easy-to-price houses in markets the company has chosen.
That model explains most of what sellers notice:
- The home must fit that program’s current criteria. Property type, condition, location and price limits vary. Do not assume that an unusual layout, deferred maintenance, damage or a tenant automatically qualifies or is automatically excluded; use the provider’s address-specific review.
- The first number is not always the final one. A quick online estimate is followed by an inspection, and the offer can move after it.
- Compare the itemized net. The same Chase page describes 5% to 6% service fees as typical, while current provider pages say the service charge varies and is shown in the offer. Include adjustment credits and closing costs instead of assuming one fixed percentage.
- Availability changes. Zillow Offers shut down in 2021 and RedfinNow closed in 2022, according to Houwzer’s rundown. Current Opendoor pages are not fully consistent about Tennessee coverage, so enter the exact address and review the resulting offer rather than relying on a general market list.
For a property that fits a current program, an iBuyer can be one option to compare. For another property, the address or condition may not qualify. The provider’s current address check and written terms are the evidence that matters.
What a real estate investor is
“Investor” covers several different kinds of buyers, and the differences matter to you:
- Fix-and-flip investors buy, renovate and resell. They price from the finished value.
- Buy-and-hold investors keep the property as a rental. They price from rent and long-term value.
- Wholesalers may contract for a property and assign the agreement when the contract and applicable law allow it. Some also close purchases themselves. Read the named buyer, assignment language, contingencies and deposit terms.
- Direct buyers may intend to take title themselves. Verify current proof of funds, the closing professional and the signed buyer entity rather than relying on the label.
The label alone does not establish certainty. Chase notes that iBuyers differ from flippers and investors, but each written offer still needs its own funding, access, inspection, cancellation, assignment and closing review. Condition may be less of a barrier for some investors, not all.
How each one calculates an offer
The iBuyer formula
An iBuyer starts from automated pricing based on your home’s features and nearby sales, then adjusts after an inspection. The seller’s cost shows up as the service fee and any repair deductions taken from the final number. The sticker offer and your net at closing are two different figures, so always ask for the line-by-line closing statement.
The investor formula
Some fix-and-flip investors use a rough seller-acquisition ceiling based on after-repair value (ARV). One version multiplies ARV by 0.70 and then subtracts repairs. Beycome’s example uses a $350,000 ARV and $40,000 in repairs, which gives $205,000 before any buyer-specific adjustment or separate assignment structure. The Motley Fool notes that market multipliers vary. This is a buyer-side screening heuristic, not a valuation, legal rule, guaranteed offer or Diamond Home Buyers formula.
Here is that arithmetic laid out so you can run your own numbers:
| Step | Example |
|---|---|
| After-repair value (ARV) | $350,000 |
| ARV x 0.70 | $245,000 |
| Estimated repairs | $40,000 |
| Rule-of-thumb offer | $205,000 |
In that simplified arithmetic, changing the repair estimate by $20,000 changes the result by $20,000. Real offers may also account for financing, holding, resale, transaction and risk estimates. Do not subtract the same repair scope twice. This account of how one owner prioritized a home renovation is a general renovation resource, not a Knoxville repair bid or endorsement.
The 70% rule is optional shorthand, not a law, market value or promise. A seller should compare the actual written price and estimated net. Diamond Home Buyers reviews the property, ownership, condition and closing requirements individually; not every property or situation qualifies.
iBuyer vs investor: side-by-side
The figures below come from the Better Business Bureau’s guidance on quick-cash sales and the Chase page above, plus how the two models work in practice.
| Factor | iBuyer | Direct investor | Traditional listing |
|---|---|---|---|
| How the offer is made | Algorithm, then inspection | Review of the property and title | Market price set by buyers |
| First offer | Typically in 24 to 48 hours | Varies by buyer | Not applicable |
| Typical closing | As little as a week, often longer | Varies; use the written date and remaining conditions | Can involve a 45-day escrow |
| Condition accepted | Decent shape, many exclusions | Varies by buyer and property | Best when prepped and staged |
| Fees | Service fees typically 5% to 6% | Agreed in the contract | Agent commission and seller closing costs |
| Prep and showings | Low | Lowest | Cleaning, staging, photos, showings |
| Complicated situations (estate, tenants, liens) | Program-specific | May be considered; verify terms | Depends on buyer, financing and title |
The BBB gives broad examples: home investors can usually close in a month or less, an iBuyer may provide a tentative offer quickly, and a financed sale can take longer. Treat those as consumer-education ranges, not Knoxville promises. Confirm title, access, contingencies and the exact date in writing. A direct sale may avoid public listing preparation, but negotiated property access can still be required.
Which one fits your situation
Your house is in good shape and you are not in a hurry
Get a traditional listing estimate and an iBuyer quote and compare them. A move-in-ready house in a strong Knoxville neighborhood can attract traditional buyers who pay for charm and condition. The BBB notes that traditional buyers may pay even more than market value for a home they love, while investors buy purely on numbers. If you have the months and the budget for prep, listing is a legitimate choice, and it should be the benchmark for every cash offer you receive.
Your house needs repairs or is unfinished
Some investors consider deferred maintenance, foundation or crawl-space issues, old plumbing, stalled renovations, fire damage or water damage that an iBuyer program may decline. The buyer may price the work into the offer, but eligibility and access still vary. See our guide on selling a house that needs repairs in Knoxville for a repair-versus-as-is comparison.
You inherited the property or have co-owners
Estates add paperwork: who has authority, whether probate is open, and whether everyone agrees. Investors who work with these sales know the questions to ask. We are a property buyer, not a law firm, so authority and probate questions belong with an attorney, and we review ownership and title before making an offer.
You are a landlord with tenants
Occupancy criteria vary by iBuyer. Some investors will consider a tenant-occupied rental, but the lease, deposits, notices and access still matter. Review our Knoxville tenant-occupied rental guide before comparing written offers.
You have a deadline
When payments, a lien, relocation or shared ownership creates a deadline, compare the buyer’s verified funds, remaining contingencies and written closing date. Cash can remove a mortgage dependency, but it does not clear title or guarantee timing. We are not a lender or foreclosure-rescue service and do not give legal or tax advice. Use the appropriate housing counselor, attorney or tax adviser alongside any offer.
Comparing net proceeds, not offers
A cash offer and a list price are not the same kind of number. To compare fairly, line up what you would actually keep.
- Start with the realistic list price. Ask an agent for comparable sales, and be honest about condition.
- Subtract listing costs. That means agent commission, seller closing costs and any concessions to the buyer.
- Subtract repairs and prep. Include the work a buyer’s inspection would likely demand, plus cleaning and staging.
- Subtract carrying costs. Mortgage, taxes, insurance and utilities for every month the house sits.
- Compare with the cash offer. A direct purchase does not require seller repairs or a listing-agent commission, so there is less to subtract. Confirm any closing costs in writing.
A higher list price does not always win once the subtraction is done, and a lower cash offer does not always lose. The gap is smaller on a house that needs work and larger on a pristine one. You can see where a direct offer might fall with our cash offer calculator for Tennessee houses and land and then run the list-price math beside it.
What to check in any written cash offer
This applies to iBuyers, investors and us alike. Before you sign:
- Proof of funds. Ask for current evidence that matches the buyer entity and purchase amount. Protect account numbers and verify the document through a trusted channel. Proof of funds is available from Diamond Home Buyers on request.
- A copy of the contract. Read it before you commit, not at the closing table.
- An answer on assignment. Ask plainly whether the contract will be assigned to another buyer. That is the wholesaler pattern.
- Escrow. Earnest money should sit with a title company or attorney, not with the buyer.
- Dates and terms. Closing date, inspection rights, contingency periods and termination clauses should all be on paper. Every verbal promise belongs in the agreement.
- No money from you. The BBB advises that you never give money to an investor before closing, that all transactions go through a closing or escrow agent, and that you should not be pressured into off-the-books payments.
- A real business behind the offer. The BBB recommends looking up the company on BBB.org and confirming it has an official name, phone number and physical address, then reading complaints and reviews.

A short Knoxville scenario

Say you own a 1970s ranch in Halls with an aging roof, dated kitchen and some crawl-space moisture. An iBuyer’s algorithm sees the age and the condition flags and either declines or sends a lower number after inspection. A traditional buyer’s inspector adds a repair list, and you either fix things before listing or negotiate credits. A direct investor walks the property, estimates the work and prices it in. You trade some price for not managing contractors, showings or a financing contingency. Whether that trade is worth it depends on your timeline and your cash, which is why the net-proceeds math comes first.
A practical comparison method
Put every route on one worksheet: realistic starting price, seller-paid costs, repair or adjustment credits, carrying costs, remaining contingencies, assignment terms, possession and the written closing date. Mark missing answers rather than assuming the best case.
Diamond Home Buyers considers as-is purchases in Knoxville, Knox County and East Tennessee. A proposed direct purchase does not require seller repairs or a listing-agent commission, but property access, price, costs and timing are confirmed in the written agreement and depend on title and due diligence. Not every property or situation qualifies.
Ready to compare a direct offer?
If your Knoxville or East Tennessee property is a house, rental, inherited home, mobile home with land or vacant lot, Diamond Home Buyers can review it for a written, no-obligation offer. A direct purchase does not require seller repairs, a public listing or a listing-agent commission; reasonable property access and other written terms still apply.

FAQ
Is an iBuyer the same as a real estate investor?
No. An iBuyer is a technology company that uses an algorithm to make an offer, then resells the home quickly. An investor is usually a person or local company that prices a house from its repaired value or rental potential and can take more conditions and complications.
Is Zillow an iBuyer?
Zillow ran an iBuying program called Zillow Offers, but it shut down in 2021. Today Zillow is mainly known as a listing site, so a Zillow estimate is not an offer to buy your house.
Is an iBuyer legit?
National iBuyers are real companies, and many sales close. Still, verify any buyer: look them up on BBB.org, confirm a physical address and phone number, and follow the BBB’s advice to pay nothing before closing. Compare the final net, not just the first quote.
Which closes faster, an iBuyer or an investor?
The BBB provides broad examples in which an iBuyer may close in as little as a week and an investor may close within a month. Those are not guarantees. The buyer, title work, property access, contingencies and signed agreement determine the actual date.
Do I pay a commission when I sell directly to a buyer?
With a direct purchase from us, there is no listing-agent commission and no seller repairs required. Closing costs and other terms are agreed in writing before you commit.
