If you've ever received a cash offer for your house and wondered, "Where did that number come from?" you're not alone.
Maybe you own an older home in Newnan that needs a roof. Perhaps you inherited a property in Fayetteville with an outdated kitchen, aging plumbing, and years of deferred maintenance. Or maybe you have a vacant rental in Griffin that needs more work than you can afford.
A cash buyer may walk through the property, ask a few questions, review recent sales, and then present an offer.
But how do they decide what the house is worth?
The answer usually involves three important pieces of information:
After-repair value (ARV): What the home may sell for after renovations.
Repair estimates: What it could cost to bring the property to the buyer's intended condition.
Offer math: What remains after repairs, resale expenses, holding costs, financing, and the buyer's desired return are considered.
Understanding these numbers can help you evaluate an offer, recognize unrealistic promises, and compare a direct cash sale with listing your home traditionally.
Let's break it down in plain English.
What Is ARV, and Why Does It Matter?
ARV stands for after-repair value.
It is an estimate of what a property could reasonably sell for after the planned renovations are completed.
Cash buyers and real estate investors often use ARV when evaluating homes that need significant repairs.
For example, imagine you own an older house in McDonough with an outdated kitchen, worn flooring, and an aging roof.
A buyer may look at recently sold homes in similar condition after renovation to estimate what your property could be worth once the work is complete.
That estimated future sale price is the ARV.
How do buyers estimate ARV?
They usually examine comparable properties, often called comps.
Good comparable sales should be similar in important ways, including:
Location and neighborhood
Square footage
Number of bedrooms and bathrooms
Lot size
Age and construction style
Garage, basement, or other major features
Overall condition and renovation quality
A renovated four-bedroom home in one Newnan neighborhood may not be a reliable comparison for a smaller, older property several miles away.
The same applies to homes in Fayetteville, Peachtree City, Senoia, and other South Atlanta communities.
Fannie Mae's appraisal guidance also emphasizes selecting comparable properties with similar physical and legal characteristics and accounting for meaningful differences. That is why a buyer should not simply choose the highest nearby sale and use it as the property's future value.
Most people don't realize: ARV is not a guaranteed sale price. It is an estimate based on comparable sales, market conditions, the planned renovation, and the property's likely appeal to future buyers.
Step 1: Buyers Estimate the Home's Future Sale Price
Let's use a hypothetical property in Fayetteville.
Assume a cash buyer reviews several recently sold, renovated homes that are genuinely comparable to the subject property.
After considering differences in size, condition, location, and features, the buyer estimates that the renovated house could sell for:
<text>Illustrative ARV: $350,000</text>
That does not mean the current distressed property is worth $350,000.
It means the buyer believes that figure may be achievable after the necessary work is completed.
The estimate can change if:
The renovation costs more than expected.
The finished home has fewer desirable features than comparable sales.
Market conditions weaken before resale.
The buyer discovers structural or title problems.
The selected comparable sales were not truly similar.
A reasonable buyer should be able to explain which sales support the ARV rather than relying on a vague statement that the neighborhood is worth a certain amount.
Step 2: Buyers Estimate Repair Costs
This is often one of the biggest factors affecting a cash offer.
A buyer must estimate what it will cost to bring the property from its current condition to the condition assumed in the ARV.
That may involve cosmetic updates, major systems, or extensive structural work.
Common repair categories
Repair categoryExamplesRoof and exteriorRoof replacement, siding, gutters, windowsHVACHeating and cooling equipment, ductworkPlumbingLeaks, damaged pipes, fixtures, water heaterElectricalUnsafe wiring, panel upgrades, outletsInteriorFlooring, drywall, painting, cabinetsKitchen and bathroomsCountertops, appliances, tile, fixturesStructuralFoundation concerns, framing, water damageExterior maintenanceLandscaping, drainage, fencing, cleanup
A home in Griffin built several decades ago may have older systems that need attention. A vacant property in South Fulton may have additional issues because small leaks, pest problems, or roof damage went unnoticed.
Why repair estimates can differ
Two buyers can look at the same house and arrive at different repair estimates.
One buyer may plan a basic rental-grade renovation. Another may intend to renovate the property for resale to an owner-occupant.
Their budgets will not necessarily be the same.
For example:
Buyer A may use durable, budget-friendly flooring.
Buyer B may plan more expensive finishes.
Buyer A may repair an existing cabinet layout.
Buyer B may replace the entire kitchen.
Buyer A may handle some work with an established crew.
Buyer B may use outside contractors at different rates.
The renovation plan matters.
Common mistake: Assuming every buyer should deduct the same repair amount. Repair estimates depend on the actual work required, local labor and material costs, permits where applicable, and the buyer's intended finished product.
A repair estimate should be more than a guess
If a buyer says your home needs $60,000 in repairs, ask what that figure includes.
Does it cover the roof? HVAC? Electrical work? Kitchen renovation? Water damage? Contractor labor? Permits?
A clear estimate helps you understand how the buyer arrived at the offer.
You do not have to agree with the estimate, but you should be able to ask questions about it.
Step 3: Buyers Account for Resale and Holding Costs
Repair expenses are not the only costs involved in purchasing a distressed property.
The buyer may also have expenses while renovating and preparing the house for resale.
These can include:
Property taxes
Insurance
Utilities
Lawn maintenance
Security
Loan interest or financing costs
Closing expenses
Resale transaction expenses
Unexpected maintenance
Contractor delays
Consider a vacant home in Coweta County.
The buyer may need several months to complete repairs, obtain inspections, coordinate contractors, and prepare the property for resale.
During that time, the property still has carrying costs.
What about unexpected repairs?
Older homes can contain surprises behind walls, beneath floors, or inside plumbing and electrical systems.
A contractor may discover water damage after removing drywall. A roof replacement may reveal damaged decking. A renovation may uncover outdated wiring or plumbing that needs additional work.
A responsible buyer considers the possibility of unexpected expenses.
That does not mean every buyer's contingency allowance is automatically reasonable. It means the offer may reflect risks that cannot be fully confirmed during an initial walkthrough.
Step 4: Buyers Consider Their Required Return
A cash buyer is generally purchasing the property as an investment or for another business purpose.
The buyer must decide whether the expected resale proceeds justify the money, time, and risk involved.
That expected return is one factor in the offer calculation.
There is no single profit margin that every cash buyer uses. Different buyers have different financing arrangements, renovation teams, business expenses, risk tolerance, and investment goals.
This is important because you may receive different offers for the same property.
One buyer may specialize in smaller cosmetic projects. Another may be comfortable with major renovations. A third may decide the property does not fit its investment criteria.
Surprising truth: A buyer's offer is not simply the home's ARV minus a repair estimate. It may also reflect resale expenses, holding costs, financing, risk, and the buyer's required return.
Understanding the Cash Offer Formula
A simplified way to understand an investor's offer calculation is:
Estimated ARV − Repair Costs − Resale Costs − Holding and Financing Costs − Required Return − Risk Allowance = Potential Purchase Offer
This is a framework, not a universal formula or a promise that every buyer calculates offers in exactly the same way.
Let's put some hypothetical numbers behind it.
A Realistic Example: How a Cash Buyer Might Calculate an Offer
Imagine a distressed property in Newnan.
The house needs a new roof, HVAC work, interior updates, and some plumbing repairs.
After reviewing comparable renovated homes, a buyer estimates the following:
ItemIllustrative amountEstimated ARV$350,000Repairs and renovation-$45,000Resale expenses-$21,000Holding and financing costs-$9,000Required return-$35,000Risk allowance-$10,000Illustrative purchase offer$230,000
The buyer's simplified calculation produces a potential offer of $230,000.
This is an educational example, not a current market valuation, a recommended offer, or an actual 678 Cash Offer calculation.
The actual numbers may be substantially different depending on the property and the buyer.
What happens if the repair estimate changes?
Suppose a contractor discovers that the roof and underlying decking need more work than expected.
The repair estimate increases from $45,000 to $60,000.
If all other assumptions stay the same, the buyer's estimated purchase offer could decrease by $15,000.
This demonstrates why repair estimates matter so much.
What happens if ARV is lower?
Suppose a more careful review of comparable sales suggests the renovated property may sell for $335,000 instead of $350,000.
With the other assumptions unchanged, the potential offer would decrease by another $15,000.
That is why the quality of the comparable sales matters. An inflated ARV can make an offer appear more attractive than the actual investment numbers support.
Is the 70% Rule Always Accurate?
You may have heard investors talk about the "70% rule."
This is a common real estate investing guideline that suggests a buyer might start by calculating approximately 70% of ARV and subtracting estimated repairs.
For example:
Estimated ARV: $350,000
70% of ARV: $245,000
Estimated repairs: $45,000
Preliminary figure: $200,000
But here's the important part:
The 70% rule is a shortcut, not a law or universal valuation standard.
It does not account for every market, property type, financing arrangement, resale expense, renovation strategy, or risk.
A buyer working in a competitive South Atlanta neighborhood may use a different approach from an investor purchasing a rural property in Meriwether County.
A homeowner should not assume that a buyer's offer is fair simply because the buyer mentions the 70% rule.
Ask for the actual assumptions behind the number.
Why Two Cash Buyers May Offer Different Amounts
If you contact three cash home buyers in South Atlanta, you may receive three different offers.
That does not automatically mean someone is being dishonest.
Buyers may disagree about:
1. The ARV
One buyer may use renovated sales from the immediate neighborhood. Another may use sales from a broader area.
The first estimate may be more reliable if the properties are genuinely comparable.
2. Repair costs
One buyer may estimate a basic renovation. Another may plan a more extensive remodel.
3. Contractor access and pricing
Buyers with established contractor relationships may have different renovation costs from buyers who hire outside crews.
4. Holding time
One buyer may expect to complete renovations quickly. Another may anticipate delays.
5. Investment strategy
Some buyers intend to renovate and resell. Others may plan to hold the property as a rental or pursue a different strategy.
6. Risk tolerance
A property with title concerns, major structural damage, or an uncertain repair scope may lead buyers to make more conservative offers.
The important thing is to compare the assumptions behind each offer—not just the final number.
How Homeowners Can Tell Whether a Cash Offer Is Reasonable
You do not need to become a real estate investor to evaluate an offer.
You just need to ask the right questions.
Before accepting a cash offer, consider asking:
What comparable sales did you use to estimate ARV?
Are those homes similar in size, location, and condition?
What repairs are included in your estimate?
Can you explain the major repair allowances?
Are holding, financing, and resale costs included in your calculation?
Are there additional fees or deductions in the purchase agreement?
Who pays the closing costs?
Is the offer subject to another inspection or price adjustment?
What is the proposed closing date?
What happens if title work reveals a lien or ownership issue?
A reputable buyer should be willing to explain the offer in straightforward language.
Watch out for these warning signs
Be cautious if a buyer:
Refuses to explain how the offer was calculated.
Uses an unrealistic ARV to make the offer sound attractive.
Changes the purchase price repeatedly without explaining why.
Pressures you to sign immediately.
Requests money upfront without a clear, legitimate contractual reason.
Uses confusing paperwork or will not give you time to review it.
Promises a closing date without considering title and payoff requirements.
You should have time to review the purchase agreement and ask questions. Consider having a Georgia real estate attorney review unfamiliar or complicated terms before signing.
What Does This Mean for Fayetteville, Newnan, and Other South Atlanta Homeowners?
Local market conditions matter.
A buyer evaluating an older house in Griffin may use different comparable sales and repair assumptions from a buyer looking at a newer property in McDonough.
Likewise, a vacant home in South Fulton may have different maintenance and security concerns from an inherited rural property in Coweta or Meriwether County.
Recent September 2026 market data illustrates why local comparisons matter. Realtor.com reported a Coweta County median sold price of approximately $401,000, while its Fayette County report showed approximately $512,650. These are countywide figures, not values for distressed homes or individual neighborhoods.
The numbers should not be used to estimate the value of your property without reviewing recent comparable sales and its actual condition.
For a meaningful evaluation, buyers should consider:
The specific neighborhood
Recent closed sales
Property size and layout
Age and condition
Lot characteristics
Renovation quality
Current buyer demand
The likely resale timeline
A home in Newnan should be evaluated against appropriate Newnan-area comparables whenever possible—not simply against a broad South Atlanta average.

Final Thoughts: Understand the Math Before You Accept an Offer
Cash buyers generally evaluate as-is homes by estimating what the property could be worth after repairs, determining the cost of the work, and subtracting expenses and the return they need to make the investment worthwhile.
That process can sound complicated, but the basic idea is simple.
The buyer is estimating what the property may be worth in the future and working backward to determine what they can pay today.
As a homeowner, you should understand the assumptions behind that calculation.
Ask about the comparable sales. Review the repair estimate. Understand the expected deductions. Compare the offer with what you might realistically receive through a traditional sale after repairs, commissions, concessions, and carrying costs.
A cash offer may be lower than the home's potential renovated value. But when a property needs substantial work, selling as-is may save time, expense, and uncertainty.
The right decision is the one that makes sense for your property and your circumstances.

FAQ
How do cash buyers determine the value of an as-is home?
Cash buyers generally review comparable sales, estimate the home's after-repair value, calculate repair costs, and account for resale expenses, holding costs, risk, and their required return.
What does ARV mean in real estate?
ARV means after-repair value. It is an estimate of what a property could sell for after the planned renovations are completed.
Do cash buyers use the 70% rule?
Some investors use the 70% rule as a preliminary guideline, but it is not a universal standard. Buyers may use different calculations based on local market conditions, repairs, expenses, and investment strategy.
Why do cash buyers subtract repair costs from their offers?
Buyers subtract estimated repair costs because they expect to spend money bringing the property to the condition assumed in their ARV estimate.
Can I negotiate a cash offer on my house?
Yes. You can ask the buyer to explain the ARV, repair estimates, and other deductions. You can also compare the offer with other buyers' offers or a traditional listing estimate.
Does a cash buyer have to show me the repair estimate?
There is no universal requirement that every buyer provide a contractor's estimate. However, asking for a written breakdown is a reasonable way to understand the buyer's assumptions.
Does selling as-is mean I don't have to disclose problems?
No. Selling as-is does not give a seller permission to conceal known material defects. Georgia seller disclosure obligations and the terms of the transaction should be reviewed carefully.
Can 678 Cash Offer buy a house that needs major repairs?
