How to Use the MAO Number in a Real Conversation
The MAO — your maximum allowable offer — is easy to calculate and hard to say out loud. On paper it is one line: (ARV × 70%) − repairs − the costs and fee you carry inside it. Across a kitchen table, it is the moment a seller hears a number lower than the one in their head and decides whether you are honest or just cheap. The number does not change. How you build it in front of the seller does. This is how to use the MAO in a real conversation: inputs first, formula second, offer last — so the seller is arguing with the arithmetic, never with you.
Do the math before the conversation, not during it
The conversation is lost or won before it starts. A MAO you calculated calmly at your desk, from sold comps you can name and a repair scope you walked, survives questions. A MAO you invent while the seller watches you think does not — and it should not, because you would not trust it either. So the first rule is boring: never walk into a seller conversation without the run already done. Run the 70% Rule / MAO Calculator, write the inputs and the output on one page, and bring that page. The First-Deal Math Pack exists for exactly this: the MAO one-pager is the sheet you can leave behind when the conversation ends.
Work the example we will carry through this whole post. Every figure is an illustration, labeled as such — your house produces its own. The example house is a 3-bed that needs real work. Three renovated homes nearby sold for $205,000, $216,000, and $209,000, which lands the ARV at $210,000. The repair scope, walked room by room: roof $9,500, kitchen $11,000, two baths $6,500, flooring and paint $7,500, systems and miscellaneous $4,500, plus a $3,000 contingency — $42,000 in total. Inside the advanced layer, the way we actually run it: $3,000 of buy-side closing costs, $4,000 of holding costs, and an $8,000 assignment fee. The calculator's answer: a maximum offer of $90,000. The seller, in this example, is hoping for $115,000. There is a $25,000 gap, and the rest of this post is about what to do with it — honestly, in the open, without moving the ceiling.
Listen first, and let the seller price their own situation
Beginners open with the number because they want the hard part over. That is exactly backwards. Open with the seller's situation: why they are selling, what the timeline actually is, what happens if the house is still theirs in ninety days. You are not stalling — you are learning which problem your offer has to solve, and a MAO only makes sense to a seller when it is attached to their problem. A seller carrying an empty house, paying taxes and insurance on it every month, hears a fast, certain, as-is closing differently than a seller testing the market. Same $90,000. Different conversation.
Ask the price question the way that produces information instead of a standoff: not 'what do you want for it?' but 'if we could close on your timeline, as-is, and you leave whatever you do not want to move — what number would make this feel handled for you?' Whatever they answer, write it down and do not react to it. Their number is data. Your job is not to beat it down in the next breath; it is to show, step by step, how your number was built — because a seller can accept losing an argument to arithmetic far more easily than losing one to a negotiator.
Say the inputs before you say the offer
Here is the order that keeps trust intact: comps first, repairs second, formula third, offer last. Walk the seller through the same three sold homes you used — addresses, sale prices, the fact that they sold renovated. Most sellers have only seen asking prices, and asking prices are wishes; showing them what finished houses actually sold for reframes the ARV without you ever calling their number wrong. Then the repair scope, itemized the way you would show a buyer: roof, kitchen, baths, floors, systems, contingency. A seller who watched you price the roof at $9,500 may disagree with the line — good, that is a conversation about a roof, which can be settled. A seller handed one unexplained discount hears only 'your house is not worth much,' which cannot.
Only then say the formula out loud, in one sentence: 'Investors who buy houses like this can pay about seventy cents on the renovated dollar, minus the repairs, minus the costs of holding and closing it — and that is where my number comes from.' Then the offer itself, stated once, plainly, with what is inside it: '$90,000 is the most I can pay and still make this work — that already has my fee in it, it is as-is, and we close at a title company on the date you pick inside the window we discussed.' Notice what that sentence does: the fee is disclosed, the terms carry weight, and the ceiling is framed as arithmetic, not appetite. You are not saying the house is worth $90,000. You are saying $90,000 is where a buyer who must renovate, hold, and resell it can stand. Those are different claims, and sellers can hear the difference.
When the seller pushes on the number, answer the input, not the pressure
The pushback comes in predictable shapes, and each one is really a claim about an input. 'Zillow says it is worth more' is a claim about ARV — answer it with the sold comps: an automated estimate has never walked the house or priced the roof, and it averages in the renovated sales without subtracting what renovation costs. 'My neighbor got $115,000' is also an ARV claim — ask, genuinely, what their house had: if it sold renovated, it belongs in the comp set at its renovated price, which is exactly how your $210,000 was built, and it still leaves the $42,000 of work between that house and this one. 'It does not need that much work' is a repairs claim — go line by line, and invite their contractor's number if they have one. Every pushback gets the same respectful move: 'Show me which input is wrong and I will re-run it right here.' That is not a tactic. Sometimes they are right.
See what a corrected input actually does, because this is the only legitimate way the ceiling moves. Say the seller produces a fourth sold comp you missed — a renovated sale at a price that honestly lifts the ARV from $210,000 to $225,000. Re-run it in front of them: $225,000 × 0.70 = $157,500, minus the same $42,000 of repairs is $115,500, minus the same $15,000 of costs and fee — the MAO is now $100,500. A $15,000 correction to the ARV moved the offer $10,500, because every $10,000 of ARV is worth $7,000 of MAO at the 70% factor. Repairs move it the other way, dollar for dollar: $10,000 more of honest repairs is $10,000 less of offer. When a seller watches a real correction change your number on the spot, the number stops being your opinion. It becomes the output of a machine they have seen work both ways — including in their favor.
When the gap is real, trade everything except the ceiling
Sometimes the inputs are right and the gap is still there — $90,000 against a $115,000 hope, in our example. This is where beginners break the rule and professionals get creative with everything around it. You can trade speed: a closing date matched to their move, not your convenience. You can trade effort: as-is, cleanout left behind, no showings, no repair list from a retail buyer's lender. You can trade certainty: earnest money in fast, a short inspection window, a title company they can call. And you can trade your own fee — know what that is worth before you offer it: cutting the assignment fee in the example from $8,000 to $5,000 moves the maximum offer from $90,000 to $93,000. That is a real $3,000, and it is yours to give. What it is not is a discovery that the math was wrong; it is you spending your margin, once, knowingly, instead of pretending the ceiling rose.
What you cannot trade is the ceiling itself, because the ceiling is not yours — it belongs to the end buyer and the renovated comp set, and an offer above MAO is a contract you cannot place, cannot close, and will eventually have to retrade or abandon. Sellers can smell a retrade coming, and they are right to. If the gap does not close, the professional move is a clean, kind walk-away that leaves the number standing: 'My $90,000 holds as long as you need it to. If your situation changes, call me and we start there, not over.' A MAO left on the table respectfully is a future deal; a blown-up contract is a burned street address and a story the seller tells their neighbors.
What never to do with the number
Four habits destroy MAO conversations, and all four are versions of the same lie. Never pad the repair estimate to justify the offer — the seller will get a second pair of eyes on that roof eventually, and one invented line costs you every true one. Never hide the fee — it is inside the number, it will be visible at closing, and a seller who learns about it from the settlement statement learns something else about you at the same time. Never promise to 'sharpen the pencil' or 'talk to your partner' to conjure a higher number with no new input — if a partner can approve $100,000 today, your $90,000 was never a ceiling, and the seller now knows your ceilings are theater. And never run the house down to defend the price: the goal is a seller who feels the arithmetic was fair, not a seller who feels insulted into signing. Pressure can produce a signature. It reliably produces a cancellation, a complaint, or a seller who stops answering the phone during the inspection window.
Close the conversation by leaving the math behind
End every MAO conversation the same way, whether the answer is yes, no, or not yet: recap the three inputs and the offer in writing, and leave the sheet. A one-page recap — the comps, the itemized repairs, the formula, the offer, the terms — does three jobs. It lets the seller re-check you after you leave, which is when trust is actually decided. It lets a spouse, an heir, or an advisor who was not in the room follow the same path you walked, instead of hearing 'some investor lowballed us' secondhand. And it makes your follow-up honest: when you call in two weeks, you are not re-pitching, you are asking whether any input has changed — a new comp, a new repair fact, a new timeline. If nothing changed, the number stands, and both of you know why.
That is the whole skill, and it is smaller than people make it: calculate the MAO before the conversation, listen before you present it, show the inputs before the offer, answer pushback at the input level, trade terms and your own fee instead of the ceiling, and leave the math on the table when you go. The investors who get their offers accepted at numbers that look low are not better talkers. They are the ones whose numbers a seller can retrace alone at midnight and arrive at the same place. Make your MAO that kind of number, and the conversation takes care of itself.
