There’s a specific mental math that almost every Long Island seller runs when they first consider listing, and it goes something like this: “My home is worth $800,000. I owe $200,000 on the mortgage. So I’ll walk away with about $600,000.”
That number is wrong. Not slightly wrong — meaningfully wrong. On an $800,000 Long Island sale, the actual net proceeds after all costs typically land somewhere between $520,000 and $560,000. The $40,000 to $80,000 gap between what sellers think they’ll net and what they actually net is the most consistent source of surprise, frustration, and post-closing regret I see in this business.
This newsletter is about closing that gap. Not by hiding costs or spinning them — the actual numbers are what they are, and Long Island transactions carry specific expenses that don’t exist in other states. But by understanding each line item ahead of time, you can plan realistically, negotiate strategically where possible, and make the sell-vs-stay decision with accurate information instead of optimistic estimates.
If you’re considering listing in the next 6-18 months, this is the piece to bookmark. Real numbers. Real breakdowns. No sales pitch. Just the honest math.
The Three Categories of Selling Costs
Before diving into specific line items, it helps to understand that the costs of selling a home fall into three broad categories, each with different timing, different negotiability, and different degrees of control.
Transaction costs are the fees paid at or around closing to complete the actual sale. Realtor commissions, transfer taxes, attorney fees, title-related costs. These are largely non-negotiable in structure and unavoidable if you want to sell.
Pre-listing costs are what you spend before your home ever hits the market. Pre-listing inspection, targeted repairs, cosmetic updates, staging, photography, professional cleaning. These are largely discretionary in amount but not in principle — some level of preparation is required for a strong outcome.
Transition costs are what you spend during marketing and after closing to move on. Moving expenses, temporary housing if there’s a gap, utility transfers, storage.
I’ll walk through each category with real numbers based on current 2026 Long Island market rates. The examples throughout use an $800,000 Nassau County home as the base case — roughly the current Nassau median — but I’ll also show how the math scales at different price points.
Transaction Cost #1: Realtor Commissions
The largest single cost of selling a home is the real estate commission. Standard Long Island practice is 5-6 percent of the final sale price, typically split between the listing agent and the buyer’s agent brokerage. On an $800,000 sale at 5 percent, that’s $40,000. At 6 percent, $48,000.
Two things worth understanding about commission that most sellers don’t:
First, the commission is negotiable in some circumstances. For very high-priced homes ($1.5M+), sliding-scale structures are common. For homes in less-competitive segments, some negotiation exists. But for the median LI home in 2026, meaningful commission negotiation is limited. What’s more important is understanding what the commission actually buys — marketing, showings, negotiation, transaction coordination, contract expertise, professional network access — and evaluating whether your specific listing agent is delivering that value.
Second, the industry structure changed materially in 2024. Following NAR settlement changes, buyer’s agent compensation is now negotiated separately in most transactions. In practice on Long Island, most sellers still offer buyer’s agent compensation because doing so meaningfully expands the buyer pool. Not offering it (or offering below-market compensation) tends to reduce showings and offers materially. But it’s a decision now, not an automatic outcome.
For the $800K example, budget $40,000-$48,000 in commission.
Transaction Cost #2: NY State Transfer Tax
New York State charges a real estate transfer tax on every home sale, paid by the seller. The tax rate is $2 per $500 of sale price (or $4 per $1,000) — effectively 0.4 percent of the sale price.
On an $800,000 sale: $3,200 in NY State transfer tax.
This is a fixed, non-negotiable cost. Every seller pays it. It’s collected at closing and remitted to the state.
For homes selling at $1 million or above, there’s an additional consideration: the New York State “mansion tax” is technically paid by the buyer, not the seller, so it doesn’t hit your net. But it does affect buyer behavior at the $1M threshold, which can affect what your home sells for and how buyers structure their offers.
Transaction Cost #3: Peconic Bay Tax (East End Suffolk Only)
If your home is on the East End of Suffolk County — specifically the five East End towns (East Hampton, Southampton, Shelter Island, Riverhead, Southold) — a Peconic Bay Community Preservation Fund tax applies. The rate is typically 2 percent of the sale price above a specific exemption threshold that varies by town.
For most Long Island sellers — anyone in Nassau or in western/central Suffolk — this tax does not apply. But for East End sellers, it’s often the second-largest transaction cost after commission. Technically paid by the buyer at closing, but it materially affects buyer behavior and what East End homes ultimately sell for.
Transaction Cost #4: Attorney Fees
New York is an attorney-driven closing state, which means you cannot close a real estate transaction without a licensed attorney representing you. This is different from many other states where title companies handle most of the closing paperwork.
Typical attorney fees for a straightforward Long Island residential closing run $1,500-$3,000 in 2026. Complex transactions (estates, short sales, title issues, unusual contracts) can push higher, sometimes to $4,000-6,000.
The attorney handles: contract review and negotiation, title search coordination, closing document preparation, escrow of deposits, communication with the buyer’s attorney and lender, and representation at the closing itself.
Cheap attorneys are rarely cheap. Attorneys who charge $800 to close a residential transaction are usually doing minimal work, missing details, or subcontracting to junior staff. The $2,000-$3,000 range for experienced counsel is where the value lives.
Transaction Cost #5: Title-Related Costs
The seller typically pays: title search ($300-$500), deed preparation ($150-$300), recording fees ($200-$500), payoff processing if there’s a mortgage ($50-$150), and miscellaneous items ($200-$400).
Total title-related costs on a Long Island sale: typically $1,000-$1,800 for the seller.
Pre-Listing Cost Categories
Pre-Listing Inspection. A comprehensive pre-listing inspection on a typical Long Island single-family home runs $400-$700 in 2026. Add-ons like radon testing ($150-$250), termite/pest inspection ($100-$200), or oil tank scan ($200-$400) can push total to $800-$1,500. Optional in principle but recommended in practice.
Repairs and Updates. Most variable line item on a seller’s cost sheet. Minimal prep (paint, minor repairs, cleaning): $2,000-$5,000. Standard prep (paint, cosmetic updates, safety items): $5,000-$15,000. Significant prep (kitchen/bath refresh, flooring): $15,000-$40,000. Most sellers land in the $5,000-$15,000 range.
Staging. Consultation only: $200-$500. Occupied staging: $500-$2,000. Vacant staging: $2,000-$6,000 initial plus monthly. Virtual staging: $50-$150 per room. For most owner-occupied LI sellers, consultation-plus-occupied is the sweet spot at $500-$2,000.
Photography. Standard MLS photography is usually included by agents. Premium package (twilight + drone + video) adds $400-$1,000. Full media suite adds $800-$2,000. For most $800K homes, upgraded photography pays back.
Transition Costs
Local move within Long Island: $2,000-$6,000. Regional (NY tri-state): $4,000-$10,000. Interstate (Sun Belt, Southeast): $8,000-$25,000. Storage: $200-$800/month. Utility transfers, address changes: $100-$500 in miscellaneous. Move-out cleaning: $300-$800.
For most local LI moves, budget $3,000-$5,000 total. For interstate relocations, $10,000-$20,000 is common.
The Hidden Cost: Capital Gains
For most Long Island sellers of primary residences, capital gains taxes are not an issue — the federal home sale exclusion allows $250,000 in gains for single filers and $500,000 for married filing jointly, provided you’ve owned and lived in the home for at least two of the past five years.
But some LI sellers — particularly those in homes purchased 25+ years ago in appreciated areas — have gains that exceed even the $500K exclusion. Federal long-term capital gains rates are 15% or 20% depending on income; New York State adds another 4-8% on top.
If your home has appreciated by more than $500K over your ownership period, consult a CPA well before listing. There are specific strategies (basis adjustments for capital improvements, timing considerations) that can reduce exposure with proper planning.
Putting It All Together: The $800K Example
Here’s the honest total on the illustrative $800K Long Island home sale:
Gross sale price: $800,000
Minus transaction costs: -$51,100 (commission $44K, transfer tax $3.2K, attorney $2.5K, title $1.4K)
Minus pre-listing costs: -$12,800 (inspection, prep, staging, premium photography)
Minus transition costs: -$4,800 (local moving + cleanup)
Total costs: approximately $68,700
Net before mortgage payoff: approximately $731,300
If there’s an existing $200K mortgage: net proceeds approximately $531,300. That’s 66% of the gross sale price ending up in the seller’s pocket. Not the 75% ($600K) that most sellers estimate when they think “sale price minus mortgage.”
How the Math Scales at Different Price Points
The percentages are similar across price points, but the absolute dollar amounts vary meaningfully. On a $600K home, expect $54K in total costs (9%). On a $1M home, $83.5K (8.4%). On a $1.5M home, $119K (7.9%). The percentage declines slightly as price rises because attorney fees, moving costs, and other fixed-cost items don’t scale proportionally.
What Sellers Commonly Underestimate
Attorney fees for anything beyond routine. Straightforward transactions run $1,500-$3,000. Estate transactions, unresolved title issues, or complicated buyer financing can push attorney fees to $4,000-$8,000.
Repair concessions during negotiation. Buyers routinely ask for credits or price reductions after inspection. Even with a pre-listing inspection, buyer’s inspectors often flag additional items. Budget $2,000-$8,000 for typical inspection negotiations.
Prorations at closing. Property taxes, utilities, HOA fees, oil in the tank. These typically cost the seller a few hundred to a few thousand dollars depending on timing.
The mortgage payoff amount is not your current balance. Your payoff includes accrued interest through the payoff date plus any prepayment fees. Typically $500-$2,000 more than your current balance shows.
Property taxes paid in advance. New York property taxes work on a fiscal year basis. Depending on when you close, you may need to reimburse the buyer for prepaid taxes or receive credit from them. Can shift proceeds by $2,000-$8,000 either direction.
How to Reduce Costs Without Hurting Outcomes
The temptation reading the above is to try to minimize every line item. Some of that impulse is smart. Some is penny-wise, pound-foolish. The honest guidance:
Where to save: Attorney fees are somewhat negotiable if your transaction is genuinely simple. Photography package can be scaled down for homes in strong markets. Staging can often be handled with consultation-only. Moving costs can be reduced substantially by doing more yourself or moving during off-peak times.
Where NOT to save: Do not skip the pre-listing inspection. Do not skip basic prep on a home going to market. Do not hire the cheapest attorney available. Do not try to save on photography for a listing that needs to compete visually. These “savings” typically cost 5-10x their amount in reduced sale price.
The one place where premium spending most consistently pays back: targeted cosmetic updates on kitchens and bathrooms. Not full remodels — those rarely pay back. But refreshes: paint, hardware, lighting, minor fixture updates. $3,000-$8,000 spent on well-chosen kitchen/bath refreshes typically produces $10,000-$25,000 in incremental sale price.
What to Do Before Listing
Get the true valuation. Book the free walkthrough conversation. Real numbers on what your specific home would list for, what net proceeds would look like after all costs, and what preparation would actually be needed. Highest-leverage single step.
Understand your specific tax situation. If your home has appreciated substantially over long ownership, consult a CPA about capital gains exposure.
Get pre-listing inspection early. Even 6 months before you plan to list, having the inspection done gives you time to plan and prioritize repairs at your own pace.
Get contractor bids for any significant repairs. Contractor pricing varies enormously and the time to shop is before you’re under transaction pressure.
Interview attorneys. Real estate closings are attorney-driven in New York. Interview 2-3 attorneys, understand their fee structures, get comfortable with their communication style.
Model different scenarios. Your agent should be able to model what different offer scenarios would net you. Understanding this ahead of time helps you make better decisions during negotiation.
The Honest Bottom Line
Selling a home on Long Island costs meaningfully more than most sellers estimate. On the median Nassau home in 2026, typical total costs run $50,000-$80,000 — roughly 6-10% of gross sale price — before mortgage payoff. Understanding this ahead of time changes how you plan, price, and negotiate.
The costs are what they are. Realtor commissions, NY State transfer tax, attorney fees, prep costs, transition costs — none of these are hidden or unusual. They just don’t make it into most seller mental math until closing day, when the reality hits.
Sellers who plan for the real cost of selling make better decisions across the board: whether to list this fall or wait for spring, how to price accurately, which prep investments to make, how to evaluate offers, and whether the sell-vs-stay math actually works for their specific situation.
The gap between what sellers think they’ll net and what they actually net is one of the most common sources of frustration in this business. Closing that gap costs nothing but a couple of hours of clear-eyed math.
