If you've ever wondered how cash home buyers calculate offers — the real math, not the vague "based on market conditions" line — you're in the right place. Most buyers in North Carolina treat their formula like a trade secret. You get a number, you're told to take it or leave it, and nobody explains where it came from.
I think that's backwards. If you don't understand how I got to my number, you can't push back. You can't compare it to listing with an agent. You can't tell whether I'm being fair or leaving money on the table. You're flying blind — and that's not how I do business.
So here's the formula. The whole thing. With actual numbers from a deal in Wake County. If our math is off on your property — if we missed an upgrade, pulled bad comps, or overestimated repairs — I want you to see it and call it out. You can also run numbers yourself using our cash offer calculator.
The Core Formula
Every number in that formula is real and verifiable. I'll break down each component with actual NC costs so you can see exactly where your number comes from — and check my math.
Component 1: After Repair Value (ARV)
This is the most important number in the calculation. ARV is what your home will be worth after it's been fully renovated — new kitchen, updated bathrooms, fresh paint, new flooring, modern fixtures, whatever the renovation requires to bring it to market-ready condition in your specific neighborhood.
ARV is not my opinion. It's not a guess. It's derived from actual recent sales of comparable homes in similar condition in your area.
Here's how we build it in a Wake County market. We look at the past 90 days of closed sales for homes that are:
- Within a half-mile of your property (tighter radius in urban areas, slightly wider in rural)
- Similar square footage — within 15-20% of your home's size
- Similar bedroom and bathroom count
- In fully renovated or retail-ready condition (since that's what we'll be selling after repair)
- On similar lot size and with comparable amenities (garage, basement, etc.)
We typically find 3 to 6 strong comps and average them, weighted toward the most recent and most similar. In a competitive area like North Hills or Cary, comps are tight and ARV is reliable. In transitional neighborhoods or rural areas, we need more data points and we price in more uncertainty.
A renovated 3/2 on the east side of Garner and one on the west side of Garner can have different ARVs even though they're a mile apart. School district lines, proximity to US-70, noise from I-40 — all of it affects buyer demand. We pull comps that are genuinely comparable, not just geographically close.
Component 2: Estimated Repair Costs
This is where most cash buyers lose sellers. Either they overestimate repairs to justify a lower offer, or they underestimate them and then reprice after inspection. Both are problems.
We walk every property before making an offer. Here's what we're looking at and roughly what each category costs in the current NC market:
| Category | Typical NC Range | Notes |
|---|---|---|
| Kitchen renovation | $18,000 – $35,000 | Full replacement; cabinets, counters, appliances, flooring |
| Bathroom renovation (each) | $8,000 – $16,000 | Full tile, fixture, vanity replacement |
| Flooring (full house) | $6,000 – $14,000 | LVP throughout; hardwood refinish adds cost |
| Roof replacement | $8,000 – $18,000 | Depends on size, pitch, material |
| HVAC replacement | $6,000 – $14,000 | Full system; common in homes 15+ years old |
| Electrical updates | $3,000 – $15,000+ | Panel upgrade, knob-and-tube replacement, code compliance |
| Plumbing updates | $2,000 – $20,000+ | Polybutylene pipe replacement adds significant cost |
| Interior paint (full house) | $4,000 – $8,000 | Professional prep and paint, trim included |
| Foundation repair | $5,000 – $30,000+ | Wide range; pier work and drainage add cost |
| Landscaping / exterior | $2,000 – $8,000 | Curb appeal work to retail standard |
For a typical 1970s or 1980s ranch in Wake County that needs meaningful updating but no major structural work, total repairs might land in the $45,000 to $65,000 range. A house with a failed HVAC, older electrical panel, and kitchen that hasn't been touched since 1994 could be $70,000 to $90,000 in renovation costs.
Polybutylene pipes — Homes built between 1978 and 1995 across Raleigh, Durham, and Charlotte often have poly pipes that insurers refuse to cover. Full replumb runs $8,000 to $20,000 depending on slab vs. crawlspace.
Red clay foundation issues — North Carolina's clay soil expands when wet and contracts when dry, cracking block foundations on older homes. Pier work or drainage solutions can add $5,000 to $30,000.
Humidity and mold — Crawlspaces in the Piedmont and Coastal Plain trap moisture year-round. Encapsulation and remediation run $3,000 to $12,000.
Termite damage — NC is in a high-risk termite zone. We see active damage or old damage on roughly 1 in 4 properties we walk. Structural repair after termites can be $2,000 for cosmetic framing patches up to $15,000+ for load-bearing member replacement.
We'd rather show you exactly what we found and explain why each line item costs what it does than pad the estimate to justify a lower number.
Component 3: Holding Costs
This one often surprises sellers. Between the day we close and the day we sell the renovated property, we carry the house for 4 to 6 months on average. Those months are not free.
On a house with an acquisition price of $185,000, here's what holding costs look like over a 5-month renovation and sale period:
| Cost Component | Monthly | 5 Months Total |
|---|---|---|
| Private money / financing cost (interest at ~9%) | ~$1,388 | ~$6,940 |
| Property taxes (Wake County rate) | ~$220 | ~$1,100 |
| Insurance | ~$150 | ~$750 |
| Utilities during renovation | ~$200 | ~$1,000 |
| Total Holding Costs | ~$9,790 |
Call it $10,000. That's real money that comes out of the deal before we make a dollar. When market conditions slow or a renovation takes longer than expected, this number grows. That's a risk that stays on our side of the ledger, not yours — but it has to be priced into the offer.
Component 4: Selling Costs on the Back End
When we sell the renovated property on the open market, we pay agent commissions just like any other seller. In NC, total commission is typically 5 to 5.5% of the resale price. On a $290,000 ARV property, that's $14,500 to $15,950 in commissions alone.
North Carolina also requires an attorney to handle every real estate closing — no title companies doing closings on their own like in some states. Attorney fees for a residential closing in the Triangle run $600 to $900. On top of that, NC charges an excise tax (sometimes called the revenue stamp) of $2 per $1,000 of the sale price. On a $290,000 resale, that's $580 in excise tax paid to the county. Add recording fees, title insurance, and any HOA-related transfer charges, and total closing costs on our end run 1 to 1.5% of the resale price — roughly $2,900 to $4,350.
Total selling costs: approximately $17,000 to $20,000 on a $290,000 resale. That's real money we spend after renovation and before we net a dollar of profit.
Component 5: Our Margin
Here's the number most buyers hide. We don't.
We target a profit of 10 to 14% of ARV on a standard renovation project. On a $290,000 ARV property, that's $29,000 to $40,600 in profit. That's our target. It's not always what we get — renovation overruns, market shifts, longer-than-expected sale timelines all eat into it. But that's the range we're aiming for.
Why does this matter to you? Because if you run the formula yourself with our repair estimates and comps, you can check whether the offer leaves us an unreasonable margin or a reasonable one. If our number works out to a 30% margin on a house that needs $20,000 in cosmetic work in a hot Cary neighborhood, something is wrong. If it works out to 12% on a house that needs $80,000 in full gut renovation in a softer market, that's a business that can function and close reliably.

A Complete Example: Wake County Ranch, Needs Full Update
Let's run a real scenario. Three-bedroom, 1.5-bath ranch on a quarter-acre lot in the Garner/Southeast Raleigh corridor. Built 1978. Original kitchen, two original bathrooms, carpet throughout, HVAC from 2008, needs exterior paint, roof has 3-5 years left.
That's roughly $139,000 to $140,000 on a house with an ARV of $290,000. At first glance, a $150,000 gap feels enormous. But that's the wrong comparison. Nobody is offering this seller $290,000 — the house needs $88,000 in work. The real question is: how much do you actually net if you list as-is on the MLS instead?
The Real Gap Is Smaller Than You Think
If this seller lists as-is on the Triangle MLS and finds a buyer at $175,000, they still pay 5.5% in agent commissions ($9,625), 1.5% in closing costs ($2,625), and the NC excise tax ($350). Even on an "as-is" sale, buyers almost always request inspection credits — call it $5,000. Add two months of carrying costs while the house sits, and the seller nets roughly $155,000.
Against our $139,300 cash offer with zero repairs, zero commissions, and a 7-day close: the actual net gap is about $16,000.
Is $16,000 worth it for some sellers? Absolutely. But for sellers who need speed, certainty, and zero hassle — who can't afford to carry the house for 60–120 days and risk the MLS buyer's financing falling through — that $16,000 difference buys peace of mind. The comparison that matters is $139,000 versus $155,000, not $139,000 versus $290,000.
| Cost Component | Cash Sale to Cinch | List As-Is on MLS |
|---|---|---|
| Agent commissions | $0 | $9,625 (5.5%) |
| Seller closing costs | $0 | $2,625 |
| Repairs / inspection credits | $0 | ~$5,000 |
| Carrying costs while listed | $0 | ~$2,400 |
| Net to seller | $139,300 | ~$155,000 |

When the Gap Is Bigger — And When to Say No to a Cash Offer
Not every situation favors a cash sale. The formula above produces a tighter gap on houses with fewer repairs needed. A house in Cary that's been maintained well, just needs cosmetic updates, and sits in a neighborhood where updated comps are $420,000? The math might look like this:
- ARV: $420,000
- Repairs: $25,000
- Holding: $12,000
- Selling costs: $25,200
- Margin (10%): $42,000
- Cash offer: roughly $315,800
That's a gap of over $100,000 to ARV — but if the seller can list as-is at $390,000 with minimal concessions and a strong agent, the net might be $360,000. That $44,000 net gap might be very much worth taking to market. We'd tell them that.
The formula works both ways. It shows us what we can offer, and it shows sellers when listing is the better move. We'd rather you understand the math and make the right choice than accept an offer that wasn't the best path for your situation.
Cash Sale vs. Listing: Side-by-Side on a $290K ARV Home
| Cash Sale to Cinch | List As-Is on MLS | |
|---|---|---|
| Sale price | $139,300 | $175,000 |
| Agent commission | $0 | -$9,625 |
| Seller closing costs | $0 | -$2,625 |
| Repairs / buyer inspection credits | $0 | -$5,000 |
| Carrying costs while listed | $0 | -$2,400 |
| NC excise tax ($2/$1,000) | $0 | -$350 |
| Net to seller | $139,300 | $155,000 |
| Time to close | 7 days | 60–120 days |
| Risk of deal falling through | Near zero | ~15% of MLS deals fail |
The real gap on this deal is about $16,000 — not the $150,000 it looks like when you compare the cash offer to the ARV. Whether speed, certainty, and zero hassle are worth $16,000 depends on your situation. For sellers facing foreclosure, divorce, or a probate timeline, the answer is usually yes.
Who Benefits Most From a Cash Offer in NC?
The math above works the same statewide, but the sellers who benefit most from a cash sale tend to be in specific situations. Across the 150+ properties I've purchased in North Carolina, the most common scenarios are:
- Inherited homes with deferred maintenance — Heirs who live out of state and can't manage a renovation from 500 miles away. Especially common in Durham and older Raleigh neighborhoods where homes have been in families for decades.
- Pre-foreclosure with an auction date approaching — When Wake or Mecklenburg County has already posted a sale date, there's no time for a 90-day MLS listing. Cash closes before the hammer drops.
- Corporate relocation on a tight timeline — Tech workers leaving the Triangle or banking professionals transferred out of Charlotte who need to close and move within 30 days.
- Properties with title complications — Liens, code violations, unpermitted additions. These are deals that traditional buyers walk away from at inspection. We handle them.
- Landlords done with problem tenants — Selling an occupied rental with non-paying tenants in NC means navigating the eviction timeline or selling as-is to a buyer who'll inherit the problem. That's us.
If your situation doesn't fit any of these, listing on the MLS with a good agent might net you more. I'll tell you that up front. Interested in learning more about how Cinch works across the state? Visit our investor page or explore our NC-wide selling guide.
Frequently Asked Questions
Because a cash buyer takes on risk and cost that a retail buyer doesn't. The cash buyer pays for repairs you don't have to make, absorbs the uncertainty of renovation overruns, carries the property for 4-6 months while renovating and selling, pays agent commissions on the back end, and provides certainty of close with no financing contingency. When you factor out commissions, repairs, carrying costs, and the risk of a retail deal falling through, the gap between a cash offer and a retail listing narrows considerably — sometimes to less than $10,000 net.
ARV stands for After Repair Value — what your home will be worth after all renovations are complete, in fully updated condition. It's calculated by looking at comparable sales (comps) of similar homes in similar condition that have sold in your neighborhood, typically within the past 90 days and within a half-mile radius. In NC markets like Wake County, comps need to be tight — a house on New Bern Avenue in Raleigh and one in Garner are different markets even though they're 15 minutes apart.
Yes. At Cinch, we'll walk you through every line of our repair estimate if you ask. Some sellers want the detail; others just want the bottom line. We're ready for both conversations. You're also welcome to get your own contractor quotes and bring them to the discussion — if your numbers are lower than ours and they're credible, we'll look at it.
For a legitimate buy-fix-sell investor in NC, a realistic target profit is 10-15% of ARV on a straightforward renovation, and up to 20% on higher-risk projects with major systems work or significant layout changes. On a $280,000 ARV home, that's $28,000 to $42,000 in profit — which sounds like a lot until you account for the 4-6 months of capital tied up, renovation risk, and carrying costs.
Yes, significantly. ARV calculations are hyper-local. What sells in North Hills in Raleigh doesn't translate to a house in the same condition in Goldsboro. Holding costs vary by market too — a house in a hot Triangle neighborhood might sell in 30 days after renovation; the same renovation in a slower market might sit for 90+, adding months of carrying costs. We run market-specific comps for every offer, not a statewide average.
That risk falls on us, not you. Once we've closed and you've been paid, our renovation cost overruns are our problem. That's one of the real advantages of a cash sale — you walk away with a fixed amount and the uncertainty of renovation stays on the buyer's side. We price that risk into our offer, which is partly why the offer is lower than retail. You're essentially selling certainty.
