Your buyer sends you a message at eleven at night. They have written a letter to the seller and they would like you to attach it to the offer. It is four paragraphs, it is warm, it is well structured, and it took them ninety seconds, because they did not write it. ChatGPT did.
The letter mentions that they are expecting their second child in March, that the backyard would be perfect for their mother who uses a wheelchair, and that they cannot wait to host Easter there. Every one of those details is a protected characteristic under federal fair housing law, and the person holding the professional exposure for passing them to a seller is you.
An AI buyer love letter is not a new legal category. It is the same old problem, arriving more often, better written, and with more detail in it than the version people used to write by hand.
The problem existed before the tools did
A buyer letter is an attempt to make a seller choose one offer over another for reasons that are not price or terms. That is the entire point of it. The difficulty is that the reasons buyers reach for are almost always the ones the Fair Housing Act protects: race, color, religion, sex, disability, familial status and national origin.
The National Association of REALTORS® has been direct about this. Its fair housing director, Alexia Smokler, has pointed out that a letter describing family holiday celebrations reveals both religion and familial status, and that if the seller then picks that offer, the seller may have broken the law. NAR’s guidance to brokers is to educate clients about the risk, to tell them plainly that you will not deliver such letters, and to document the objective reasons behind whichever offer is accepted.
None of that depends on who or what typed the sentences.
What AI actually changes
Three things, and they all point the same way.
- Volume. Writing a heartfelt letter used to take an evening, so most buyers did not bother. It now takes under two minutes, so far more of them arrive on your desk.
- Detail density. Ask a model to make a letter personal and it will mine everything you gave it. Buyers feed it their whole situation, and the model treats children, faith, health and origin as color rather than as liability.
- Confidence. The output reads well. A clumsy handwritten note looks like what it is. A polished four-paragraph letter looks like something a professional signed off on, which makes it easier for everyone in the chain to stop reading it critically.
The pattern is the same one that shows up in AI-written listing copy: the model is not trying to discriminate, it is trying to be vivid, and vivid is exactly where fair housing problems live.
The one state that tried to ban them
This is worth knowing because it comes up in the conversation, and most agents remember only half of it.
In July 2021 Oregon became the first state to prohibit buyer love letters outright, through House Bill 2550, which barred sellers’ agents from passing on any communication other than customary documents. A brokerage challenged it. On 3 March 2022 a federal judge in Total Real Estate Group v. Strode granted a preliminary injunction, finding the ban an overbroad restriction on protected commercial speech, and noting that the state had less restrictive options available, including redaction and mandatory fair housing disclosures. By May 2022 the state had conceded and the ban was permanently off the books.
So the letters are legal. That is genuinely all the case decided. It did not decide that acting on one is safe, and it did not touch the Fair Housing Act, your state’s own advertising and discrimination rules, or Article 10 of the Code of Ethics. A practice can be constitutionally protected and still be the thing that costs you your license.
The four positions agents take
There is no single correct answer here, and brokerages genuinely differ. These are the four that exist in practice.
| Position | What it means | Where it goes wrong |
|---|---|---|
| Blanket refusal | You do not write, edit or deliver letters, on either side | Nowhere, legally. You may lose a client who thinks you are not fighting for them |
| Deliver unread | You forward whatever the buyer wrote without looking | You cannot claim ignorance of a document you handled, and “I did not read it” is not a defense anyone enjoys giving |
| Deliver after redaction | You strip protected-class references and keep the rest | Workable, but you now own the judgment about what counted as protected, every time |
| Terms only | The buyer writes about the offer, not about themselves | Nowhere, and it is often more persuasive anyway |
Ask your broker which of these is the house position before the situation arrives, not during it. If the answer is that nobody has thought about it, that is useful information too.
What to say when the buyer asks
The instinct is to talk about the law. It lands better if you talk about their offer.
I can’t pass that one along, and it’s not a technicality. It tells the seller you’re expecting a baby and that someone in the family uses a wheelchair. If they pick you and the other buyer ever asks why, those two sentences are the whole case. Sellers’ agents know this, which is why a lot of them throw these out before the seller sees them.
What does move the needle: you’re conventional at eighty percent down, you can close in twenty-one days, and you’ll take the shed. Let me put that in writing instead.
Most buyers accept this immediately, because you have not told them no, you have told them what works. The ones who push back are usually in a bidding war and frightened, and the honest answer is that the letter was never the thing that was going to win it.
If your brokerage does allow them
Then read every one before it goes anywhere, and take out anything in this list. AI-written letters trip most of these at once, because personal detail is precisely what you asked the model for.
- Children, ages, schools, pregnancy, “growing family”, “starting a family”
- Any religion, place of worship, or religious holiday
- Disability, accessibility needs, medical history, aging parents moving in
- Country of origin, first language, immigration status, family surnames offered as heritage
- Marital status, “my husband and I”, “as a single mother”
- Photographs of anyone, and any link to a personal social profile
- Anything about the neighborhood’s people rather than the neighborhood’s features
That last one catches people. “We love how family-friendly the street feels” is a statement about who lives there. The same instinct causes trouble in listing descriptions, which is why the prompts that work for MLS remarks all forbid describing the buyer.
A prompt that produces the version you can actually send
If the buyer is going to use AI regardless, and they are, give them a prompt that keeps the letter on the offer. Send them this rather than arguing.
Write a short note from a buyer to a seller, under 150 words, to accompany an offer.
The offer: [price], [financing], [deposit], [closing date], [contingencies waived or kept], [anything you are flexible on].
What I noticed about the house: [two specific things — the workshop, the trees, the fact it has one owner].
Rules: write only about the offer and the house. Do not mention my family, my children, my religion, my health, my job, my background or my reasons for moving. No adjectives about me. No photographs. End with the closing date and nothing else.
The result is short, specific and boring in the way a strong offer is boring. It also tends to be more persuasive than the emotional version, because a seller reading it learns something they did not already know: that this buyer will not fall out of escrow.
On the listing side
If you represent the seller, the letters arrive at you. Decide in advance and put it in the listing agreement conversation: you will not forward buyer letters, and here is why. Sellers accept this far more readily than agents expect, because the risk being described is theirs.
Document the offer comparison in objective terms — price, financing, contingencies, timeline — the same way you would document any recommendation you made using a tool rather than a spreadsheet. The reasoning behind that habit is the same one covered in the piece on where AI helps with a CMA and where it does not: the number and the narrative need to be defensible separately.
Common questions
Are buyer love letters illegal?
No. One state tried to ban them and the ban was struck down on First Amendment grounds in 2022. What remains illegal is choosing a buyer on the basis of a protected characteristic, and a letter is the most common way that information reaches the person making the choice.
Does it matter that AI wrote it?
Not to your liability. It matters to the volume and to the amount of protected detail per letter, which is a practical problem rather than a legal one. The same principle applies when a model explains a contract clause: anything reaching your client through you is yours, which is the subject of the piece on AI and contract questions. When to mention AI involvement at all is worked through in the piece on telling a client you used AI.
Can I just redact the risky parts?
You can, and the Oregon court specifically pointed to redaction as one of the less restrictive alternatives available to a state. The catch is that you are then making a judgment call on every letter, in writing, on the record. Some brokerages are comfortable with that. Ask before you assume yours is.
What if the other buyer sends one and mine does not?
Then the other buyer has handed the seller a fair housing problem and you have not. In a genuine multiple-offer situation, terms decide it. If you want an edge that is entirely within your control, put it in the follow-up instead, using the approach in the piece on follow-up emails.
Should I write one for my buyer myself?
If your brokerage allows letters at all, drafting one yourself is the version where you control the content completely. It is also the version where your name is on it. Most agents who think this through end up at terms only.
