using 70-95% of an appraised value can compensate for selling costs of 5-30% depending on time and market
You bought a condo for $320,000 five years ago. Zillow says it's worth $380,000 - a $60,000 gain on paper. You list it, a Buyer negotiates to $372,000, and then $18,600 in Commissions, $9,300 in Closing Adjustments, and $4,000 in repairs come off the sale price. You receive $340,100. Your actual gain is $20,100 - about a third of what the paper number promised.
Selling costs are the transaction frictions - Commissions, Closing Adjustments, preparation - between an asset's sale price and the cash that actually hits your account. For liquid assets like stocks you lose almost nothing; for illiquid assets like real estate or equipment, multiply appraised value by 0.70 to 0.95 to estimate what you'd actually pocket.
Selling costs are every dollar subtracted between an asset's sale price and the cash that reaches your account - strictly the transaction frictions of converting an asset to cash. They include:
Selling costs do not include price concessions you negotiate with a Buyer. If a Buyer talks you down $8,000 off your asking price, that is a pricing outcome, not a transaction friction. The distinction matters: selling costs are largely predictable before you list, while price concessions depend on negotiation and market conditions.
For liquid assets like publicly traded stocks, selling costs are negligible - under 0.03%. For illiquid assets, the practical rule of thumb is to multiply appraised value by 0.70 to 0.95 to estimate what you'd actually receive. Where you land in that range depends on how fast you need to sell, how many Buyers are competing, and the asset type.
Selling costs show up every time you convert an asset to cash - and Operators touch assets constantly.
On the P&L side: if you buy inventory for $100K and need to liquidate it, you might only recover $70-85K after Liquidation Discounts and Commissions. That $15-30K gap is a real cost on your Operating Statement.
On the Balance Sheet side: your net worth on paper includes the appraised value of everything you own. But what you'd actually have if you converted everything to cash today is lower by the sum of selling costs across all your illiquid assets. A $500K house with 8% selling costs contributes $460K to your practical net worth, not $500K.
This matters for every Capital Investment decision. The true break-even on an asset isn't the price you paid - it's the price you paid plus selling costs on both ends (what it cost to buy, and what it will cost to sell). An asset that appreciated 5% on paper may be a loss once you account for 8-10% in total round-trip transaction frictions.
Selling costs scale with three variables:
1. Asset type determines the baseline
| Asset | Typical Selling Costs | Why |
|---|---|---|
| Publicly traded stocks | 0.01-0.03% | Electronic, standardized, huge Buyer pool; zero-commission platforms mean the only friction is the gap between bid and asking price |
| Car (private sale) | 5-10% | Time, listing effort, negotiation |
| Real estate | 7-10% | Commissions (4-5.5% total post-2024) + Closing Adjustments + preparation |
| Small business | 15-25% | Complex Valuation, broker Commissions, extended transaction timelines |
| Specialized equipment | 20-30%+ | Tiny Buyer pool, Liquidation Discounts |
A note on real estate Commissions: before August 2024, 6% total (split between listing and buyer agents) was standard. After the NAR settlement, sellers typically pay 2.5-3% to their listing agent, and buyer agent compensation is negotiated separately - usually 1.5-2.5%. Total Commissions now run 4-5.5% in most markets.
2. Time pressure increases costs
Selling a house over 6 months in a normal market might cost 7-9%. Needing to sell that same house in 30 days could cost 15-20% because you accept a lower bid to meet your deadline. This is the Liquidation Discounts principle: the faster you need Cash Flow, the more you leave on the table.
3. Market conditions shift the range
When Demand exceeds supply, selling costs compress toward the low end because multiple Buyers compete and you hold pricing leverage. In a Market Downturn, they expand toward the high end because fewer Buyers exist and those who remain negotiate harder.
Apply selling cost estimates whenever you:
You bought a condo for $320,000 five years ago. Current appraised value is $380,000. You want to sell and relocate. This is your primary residence.
You list at $380,000. A Buyer negotiates to $372,000 - an $8,000 price concession. (This is a pricing outcome, not a selling cost, but it reduces what you receive.)
Commissions at 5% of sale price: $372,000 x 0.05 = $18,600 (listing agent 2.75% + buyer agent compensation 2.25%)
Closing Adjustments (transfer tax, legal, title): $9,300
Pre-sale repairs and preparation: $4,000
Total selling costs (transaction frictions only): $18,600 + $9,300 + $4,000 = $31,900
Cash received: $372,000 - $31,900 = $340,100
Actual gain over purchase price: $340,100 - $320,000 = $20,100
Insight: The appraised value showed a $60,000 gain. Selling costs consumed $31,900 and the price concession took another $8,000 - leaving $20,100 in actual gain, roughly one-third of the paper number. Because this is a primary residence, the gain falls well under the $250K/$500K exclusion threshold, so taxes on the profit are not a factor here. On a rental or investment property, taxes on the sale profit plus taxes owed on previously deducted Depreciation could take another $20-40K depending on your tax brackets - a point the first exercise below explores.
Your company has $200,000 in specialized equipment (appraised value). Your warehouse lease ends in 30 days and you need to clear everything out.
You list equipment on industry marketplaces. Specialized gear has a tiny Buyer pool.
A liquidator offers $140,000 for everything - a 30% Liquidation Discounts haircut from appraised value.
Alternative: sell piece by piece over 6 months. Estimated recovery: $170,000. But you'd need $2,000/month in storage at another facility.
Piecemeal 6-month path: $170,000 - $12,000 storage = $158,000, plus 6 months of your time managing individual sales.
You take the liquidator's $140,000 (70% of appraised value) because the opportunity cost of 6 months exceeds the $18,000 difference.
Insight: Time pressure pushed selling costs from ~15% (patient sale) to 30% (forced sale). On $200K of assets, that is a $30,000 difference - the literal price of urgency. This is why Operators plan Exit Sequencing before they need it.
Selling costs are transaction frictions - Commissions, Closing Adjustments, preparation. Price concessions from negotiation are a separate concept. Keeping the definition tight lets you estimate selling costs before you list.
An asset must appreciate beyond its round-trip selling costs (buy side + sell side) before you truly break-even. A 5% paper gain can be a net loss after 8-10% in total transaction frictions.
The more illiquid the asset, the wider and more volatile the selling cost range. Publicly traded stocks cost under 0.03% to sell; specialized equipment can cost 30%+.
Treating appraised value as money in your pocket. Your practical net worth is always lower than your paper net worth by the total estimated selling costs across all illiquid assets.
Ignoring selling costs when calculating Returns on a purchase. True ROI must include costs on both the buy side and the sell side, which is why short holding periods on illiquid assets almost always lose money.
Lumping price concessions (what the Buyer negotiated off your asking price) together with selling costs (the frictions you pay regardless of final sale price). Both reduce what you receive, but only selling costs are predictable in advance.
You own a rental property with an appraised value of $450,000 and a mortgage principal balance of $280,000. You originally purchased it for $350,000 and have claimed $40,000 in Depreciation deductions over the years. Estimate your pre-tax equity (cash received minus mortgage principal) under three scenarios: (a) patient sale when Demand is strong, (b) normal market over 3-4 months, (c) must sell within 45 days during a Market Downturn. Then explain what additional cost would reduce the cash you actually keep.
Hint: Use the 0.70-0.95 range for illiquid assets. Strong/patient: ~94%. Normal: ~89%. Forced during downturn: ~75%. Subtract the mortgage principal from cash received. For the additional cost: this is a rental property, not a primary residence - think about what happens when you file taxes on the profit and on the Depreciation you previously deducted.
(a) Strong/patient: $450K x 0.94 = $423K. Pre-tax equity = $423K - $280K = $143K. (b) Normal: $450K x 0.89 = $400.5K. Pre-tax equity = $400.5K - $280K = $120.5K. (c) Forced/downturn: $450K x 0.75 = $337.5K. Pre-tax equity = $337.5K - $280K = $57.5K. The same property yields anywhere from $57.5K to $143K in pre-tax equity - an $85.5K swing driven entirely by selling costs and market conditions. Tax warning: because this is a rental property (no primary residence exclusion), you would owe taxes on the profit from the sale and owe additional taxes on the $40K of Depreciation you previously deducted. Depending on your tax brackets, that could reduce your cash by $20-40K beyond the selling cost estimates above. These exercise numbers show pre-tax equity only - the actual cash you walk away with is lower.
You are evaluating whether to buy a $25,000 piece of equipment for your business. You expect to use it for 2 years, then sell it. Similar used equipment sells for about 60% of purchase price after 2 years of Depreciation. Selling costs for used equipment in your industry run about 15%. A rental alternative costs $550/month. Which option has a lower direct cost over 2 years, and what does this analysis leave out?
Hint: Compute the equipment's resale market value after Depreciation, then apply selling costs to the resale value (not the purchase price). Total ownership cost = purchase price minus cash received after selling costs. Compare to 24 months of rental. For what is missing: think about what else $25K could do if you did not tie it up in equipment, and what ongoing ownership costs exist beyond the purchase price.
Resale market value after 2 years: $25,000 x 0.60 = $15,000. Cash received after 15% selling costs: $15,000 x 0.85 = $12,750. Total direct cost of ownership: $25,000 - $12,750 = $12,250. Rental alternative: $550 x 24 months = $13,200. Buying is $950 cheaper on direct cost alone. Without accounting for selling costs, you would estimate ownership cost at $25K - $15K = $10K, making buying look $3,200 better. Selling costs cut that advantage by 70%. What this leaves out: (1) opportunity cost - tying up $25K in equipment means those dollars cannot earn Returns elsewhere; even at 5% annual return that is roughly $2,500 over two years, which flips buying from $950 cheaper to $1,550 more expensive than renting. (2) Maintenance and insurance - ongoing ownership costs that rental pricing already includes. (3) Execution Risk on the sale itself - if the Buyer pool is thinner than average, actual selling costs could exceed 15%. When the margin is this thin, renting is likely the better choice.
Selling costs are one of the first concepts that separate paper value from real value - a distinction that runs through almost everything in personal finance. This concept feeds directly into Liquidation Discounts (what happens when selling costs hit their extreme upper range under forced timelines), Closing Adjustments (the specific line items that make up the non-Commission portion of real estate selling costs), and the rent-vs-buy decision (where selling costs are a hidden ownership cost that tips the math toward renting for short Time Horizon scenarios). When you study net worth, you will discount every illiquid assets line by estimated selling costs to get a realistic picture. When you encounter opportunity cost, selling costs become part of the hold-vs-sell calculus - sometimes the cost of converting an asset exceeds the benefit of redeploying that capital, making 'hold' the correct choice even when you would rather move. And when you reach Capital Investment analysis, you will see that every asset acquisition carries an implicit selling cost that must be recovered through Appreciation or Cash Flow before the investment pays off.
