How It Works

Seller Closing Costs

Sellers typically pay 7-10% of the sale price in closing costs. Understanding these costs helps set a realistic net proceeds expectation.

Major Seller Costs

  • Agent commission: The largest cost, typically 4-6%
  • Transfer tax / deed stamps: State and local taxes on the property transfer
  • Title insurance: Seller may be responsible for the owner policy (varies by state)
  • Attorney fees: Required in some states for settlement

    • Prorations and Adjustments

  • Property taxes are prorated to the closing date
  • HOA dues prorated or transfer fees charged
  • Seller responsible for any liens, judgments, or payoffs

    • Negotiable Items

    Seller concessions toward buyer closing costs are common negotiation tools. Limits apply: conventional loans allow 3-9% seller concessions depending on buyer down payment.

    Worked Example

    A $450,000 sale with 5% commission, 0.5% transfer tax, $1,200 title, $750 attorney, $200 recording, $300 HOA, $5,000 seller concessions.

    sale_price = 450000commission_pct = 5transfer_tax_pct = 0.5title_insurance_seller = 1200attorney_fee = 750recording_fees = 200hoa_fees = 300seller_concessions = 5000
    1. 01Commission: $450,000 x 5% = $22,500
    2. 02Transfer tax: $450,000 x 0.5% = $2,250
    3. 03Title insurance: $1,200
    4. 04Attorney fee: $750
    5. 05Recording fees: $200
    6. 06HOA transfer fee: $300
    7. 07Fixed costs: $1,200 + $750 + $200 + $300 = $2,450
    8. 08Seller concessions: $5,000
    9. 09Total: $22,500 + $2,250 + $2,450 + $5,000 = $32,200
