Dual Agency in Real Estate: Why “In-House” Deals Can Cost You More

The Misconception That Can Cost You Thousands

In Westchester County—and across Putnam, Dutchess, Rockland, and Connecticut—many buyers and sellers believe they’re getting a financial advantage by working directly with the listing agent or choosing a brokerage that brings in its own buyer.

On the surface, it sounds like a smart move:

But here’s the reality:

That “savings” can come at a much higher cost.

The Real Issue: Conflicted Representation

When One Brokerage Handles Both Sides

When a listing agent or brokerage represents both the buyer and the seller, it creates what’s known as a dual agency situation.

And that changes everything.

Instead of having someone fully advocating for your best interests, the agent is now required to remain neutral—limiting what they can say, advise, and negotiate.

Why “In-House” Deals Aren’t Always a Win

What You Gain in Convenience, You May Lose in Protection

Here’s what’s really happening behind the scenes:

  1. The brokerage represents both sides simultaneously
    This creates a built-in conflict of interest from the start.
  2. Incentives may not align with your goals
    Some brokerages offer bonuses for “double-ended” deals—prioritizing closing the deal over maximizing your outcome.
  3. You lose undivided loyalty and full disclosure
    Buyers and sellers often don’t realize they’re giving up critical guidance that could impact their finances.
  4. The listing agent may effectively represent both parties
    Even if they’re not officially your agent, their role becomes divided.
  5. The same applies to buyer’s agents within the brokerage
    Representation can become blurred, even when roles appear separate.
  6. Negotiation power is limited when it matters most
    If issues arise—like repairs, pricing, or contract terms—the agent cannot fully advocate for either side.

Why the “Commission Savings” Can Be Misleading

What You Save Upfront May Cost You Later

A commission discount can feel like a win.

But the real question is:

What are you giving up in exchange for that discount?

Without full representation:

Even a small shift in negotiation can cost far more than any perceived savings.

The Question Every Buyer and Seller Should Ask

Who Is Actually On Your Side?

Before moving forward with any “in-house” deal, ask yourself:

Because in a dual agency situation, the answer is often: no one completely.

Why Full Representation Matters

Dedicated Advocacy Protects Your Outcome

A true buyer’s or seller’s agent is fully committed to:

That level of advocacy is what ultimately protects your money.

The Bottom Line for NY & CT Buyers and Sellers

Across Westchester, Putnam, Dutchess, Rockland, and Connecticut:

Convenience should never come at the cost of representation.

An “in-house” deal may seem easier—but it often introduces risks that can directly impact your final outcome.
