Best Offer Wins: A House, a Deadline, and a Woman Out of Options

Margo Miyake and her husband Ian have lost eleven bidding wars in a row.

Their reward is a 600-square-foot apartment in Washington, D.C., a stack of rejected offers, and a clock ticking on the adoption process they hope to begin.

Then a tip arrives: a renovated 1940s Colonial in Bethesda, Maryland, is about to hit the market off-list.

Best Offer Wins by Marisa Kashino follows what Margo does with that tip — and how far past the ordinary rules of house hunting she travels.

Set against a housing market defined by low supply, high rates, and all-cash buyers, the novel moves from social maneuvering into something considerably darker.

TL;DR: The Short Version

The setup: A PR executive trapped in a tiny D.C. apartment loses her eleventh bidding war and decides she will not lose a twelfth.
The escalation: She tracks the sellers, infiltrates their lives, uncovers a plagiarism secret, and uses it as leverage.
The line crossed: When leverage is not enough, she removes the competition — permanently.
The themes: Housing desperation, curated suburban perfection, marital betrayal, and the small steps that lead to enormous ones.
The tone: Sharp, anxious, and darkly comic on the way to something considerably worse.

Who Will Enjoy This Book

Readers drawn to domestic suspense with an unapologetic antiheroine will find familiar ground here, as will anyone who has followed a real estate market gone strange and wanted to laugh nervously about it.

The novel leans on dark humor as much as tension, and Margo narrates her own decisions without apology.

It suits readers of satirical thrillers, stories about status anxiety and suburbia, and books where the marriage at the center is less a romance than a negotiation.

Best Offer Wins Summary (Spoilers Ahead)

Spoiler warning: the following section describes the plot in full, including the ending.

Margo Miyake is thirty-eight, a vice president at the public relations firm Buzz Inc., and she is running out of time. She and her husband Ian sold their starter row house to fund a bigger purchase and have spent eighteen months losing bidding wars to all-cash buyers.

Their apartment in Shaw is small enough that Margo feels it physically. She wants a house before adoption home studies begin, and she repeats a private mantra at night: no house, no baby.

Her agent, Ginny Gunther, calls with a lead. A renovated 1940s Colonial at 5423 Stonebrook Avenue in Bethesda will list off-market before going public, and the owners — Georgetown economics professor Curtis “Curt” Bradshaw and his husband Jack Lombardi — are still deciding how to proceed.

Margo drives out immediately and falls for the house on sight. White brick, marble kitchen, primary suite, tire swing in the yard. She also learns the sellers intend to list publicly with the area’s dominant agent, Theresa Reynolds.

Rather than wait, Margo researches the couple online and finds Jack’s hot yoga studio. She enrolls, engineers an accidental meeting, and claims she is managing adoption stress. Jack, warm and open, invites her and Ian to dinner.

At dinner, Margo pitches an off-market purchase for $1.3 million. Then Ian mentions their agent’s name, and Jack realizes Margo found him through his yoga class. Curt throws them out and threatens to call the police if they return.

Margo does not stop. Scrolling one-star reviews of Curt’s bestselling economics book, Falling Apart, she finds an anonymous warning from a user called “Ellipsis”: DO NOT TRUST CURTIS BRADSHAW.

She works backward through Curt’s old Georgetown syllabi, calls former students, and eventually reaches Chloe Nelson. Chloe describes Dorothy “Dottie” Ross, Curt’s star student, who vanished in March 2019.

Margo tracks Dottie to an antique shop in Berkeley Springs, West Virginia, and poses as a journalist named Lisa Waters. Dottie tells her the truth: Curt plagiarized the entire first chapter of Falling Apart from her undergraduate paper.

When Dottie confronted him, Curt’s wealthy father paid her $50,000 in cash and cleared her student loans to buy her silence. Margo leaves with the story and a purpose.

She corners Curt in his Georgetown office and threatens to expose him to King’s College in London, where he has accepted a new post. He agrees to steer the house to her offer when it lists on Thursday.

Meanwhile, Margo finds a black Nokia flip phone on her kitchen counter. Ian is having an affair with Alex Stapleton, an EPA colleague. Margo needs Ian’s income and marital status to qualify for the mortgage, so she confronts him, weaponizes his guilt, and makes him sign the purchase paperwork with a new agent, Derrick.

Thursday arrives. The house lists at $1.25 million, and Margo and Ian submit $1.3 million with no contingencies. Curt does not deliver, and Theresa Reynolds refuses early offers, setting a Monday deadline after a weekend open house.

That same day, Margo takes a pregnancy test. It is positive. Now she is certain that another bidding war will trap her unborn child in the apartment.

On Sunday night, she borrows her neighbor Natalie’s red hatchback and steals a silver wrench from Natalie’s toolbox. She drives to Alex’s apartment on Capitol Hill, kills her with the wrench, and packs the body into Natalie’s black suitcase.

Knowing Jack, Curt, and their daughter Penny are away for the weekend, Margo drives to Bethesda and carries the suitcase through an unlatched basement Dutch door she had noticed earlier. She returns Natalie’s car and wrench and waits.

Monday, prospective buyers find the suitcase. Police cordon off the street, and cable news turns the property into the “Murder Mansion” under the hashtag #BethesdaBasementBody.

Buyers withdraw en masse. Then a televised press conference shows surveillance footage of a red hatchback and a hoodie-clad figure unloading a suitcase — and Ian recognizes Natalie’s car.

Margo narrates her reasoning directly to the reader. She explains that she could not have killed Ian because she needed his salary, and that framing Natalie required only Natalie’s own belongings.

When Ian threatens to call the police, Margo explains why the sellers never will. She and Ian are now the only buyers willing to purchase a house with a murder in its basement — and Curt and Jack need that sale to fund their move to London.

She shows Ian the pregnancy test. He breaks.

In the Epilogue, Margo and Ian live at 5423 Stonebrook Avenue. Jack and Curt accepted the $1.3 million offer without negotiation and left for London. Investigators concluded that Natalie killed Alex in a jealous rage and then disappeared or died by suicide.

Margo decorates a coral nursery for her baby girl. Ian spends his nights and weekends compulsively renovating the basement. The novel ends with Margo hearing a faint buzz from Ian’s backpack, where she finds a new vibrating Nokia burner phone, while his power saw roars below.
