Make the Offer On the Call: Comps to ARV to MAO

The callback is where deals go cold

"Let me run the numbers and get back to you" feels like the safe thing to say. It isn't. Every hour between the call and the callback is an hour a seller can talk to another buyer, a family member with an opinion, or their own doubts. On a virtual floor running leads through several VAs across time zones, that gap compounds - the rep who took the call at 9am local isn't always the one available to close the loop at 2pm, and the lead sits in between. Making the offer on the call - walking a seller from condition to comps to a number before you hang up - closes that gap. It isn't a sales trick; it's a math problem you solve fast enough to still be useful.

Why speed matters more than sellers say it does

Motivated sellers rarely say "I need this fast" - but the underlying research on lead response is blunt about what happens when a fast-moving lead sits. The often-cited Lead Response Management study (run with InsideSales.com, MIT, and Harvard Business Review researchers) found contact and qualification rates fall off sharply once a lead goes more than a few minutes without a response, and later InsideSales analysis of tens of millions of sales interactions found conversion odds highest in the first five minutes after a lead comes in. That research was done on inbound B2B leads, not distressed-property sellers - the exact multiplier doesn't transfer one-for-one - but the mechanism does: a seller who called because something in their life just became urgent (a lis pendens letter, a tenant who stopped paying, a house they inherited and don't want) is primed to act while the urgency is fresh, and that window closes the longer you make them wait on you.

The practical version for a wholesaler: the deal isn't won by the best number, it's won by the number the seller hears while they're still willing to talk. A mediocre offer delivered live beats a great offer delivered in a follow-up text two days later that never gets opened.

What you need in hand before comps even come up

You can't shortcut a number you don't have real inputs for. Before you try to build an offer live, get three things from the seller in the discovery part of the call:

Property basics: square footage, bed/bath count, and roughly when it was last updated.
Condition, in the seller's words: roof age, foundation issues, whether systems (HVAC, electrical, plumbing) have been touched recently. You're not doing an inspection - you're building a repair-cost range, not a precise number.
Occupancy and access: tenant-occupied, vacant, or owner-occupied changes both your repair estimate and your timeline assumptions.

If you can't get a real answer on condition - the seller is vague, defensive, or clearly doesn't know - that's a signal to slow down, not to guess and quote a number anyway. A wrong number said with confidence is worse than no number.

Comps to ARV, the version that works from a phone screen

The defensible way to build after-repair value is from comparable sales, not from a gut feel about "what houses go for around here." The standard method: pull sold, renovated comps within a half-mile, sold in the last 90–180 days, within about 10% of your subject property's square footage and matching bed/bath count, then average their price per square foot and multiply by your subject's square footage. That's slower than you have time for mid-call - so the live-call version is a compressed pass:

Pull 3 comps from whatever tool you already have open (MLS access, PropStream, Zillow sold filter) while the seller is still talking through condition.
Average price-per-square-foot across those 3, multiply by the subject's square footage. That's your working ARV.
Say it's a working number, not a final one - "based on what's sold nearby, I'm seeing your house land somewhere around [X]" keeps you honest and keeps the seller from anchoring on a figure you haven't verified.

This is a fast estimate, not an appraisal. Treat it as a placeholder you'll tighten before contract, and tell the seller that directly - trust survives a caveat; it doesn't survive a number that changes without explanation later.

ARV to MAO: the formula and the part everyone leaves out

Maximum Allowable Offer is the ceiling you can pay and still have room for repairs, holding costs, your assignment fee, and margin for whoever closes the deal:

MAO = (ARV × investment percentage) − estimated repair costs

The investment percentage is usually written as "the 70% rule," but treat 70% as a starting point, not a law. It leaves roughly a 30% buffer to cover repairs, holding costs, closing costs, and profit - investors commonly flex it to 75% in competitive markets with light rehab needs, and down to 60–65% in slower markets or on heavier rehabs. The part that gets skipped in most explanations: that percentage has to leave room for your assignment fee on top of the end buyer's margin, not instead of it. National assignment-fee data (from a wholesaler survey run by Real Estate Bees) puts the average fee around $13,000, with a standard range of roughly $7,500–$15,000 on typical single-family deals in the $150k–$300k ARV band - lower on thin-margin deals, higher on distressed assets with real spread. If your MAO doesn't leave room for that fee, you're not underwriting a wholesale deal, you're underwriting a direct-to-rehabber deal and calling it something else.

Worked example: ARV of $220,000, repair estimate of $30,000, working at 70%. MAO = ($220,000 × 0.70) − $30,000 = $154,000 − $30,000 = $124,000. That's the number you can defend to the seller, and it's the number that still leaves an end buyer their own margin after your fee.

Saying the number out loud

The math is the easy part. The hard part is not flinching when you say it, because a below-asking number read in a shaky voice sounds like an insult even when it's fair. Two things fix that:

Frame the number as math, not opinion. "Based on what's sold nearby and what the repairs will run, here's where I land - [number]" reads as a calculation. "I think it's worth about [number]" reads as a lowball guess.
Pause after the number. Silence after an offer feels uncomfortable, and new reps fill it with justification that undercuts the number they just gave. Let the seller respond first.

If the seller's reaction tells you the number is wrong for their situation - not "too low," but genuinely disconnected from a repair item you didn't know about, or a comp that doesn't actually apply - that's new information, not an objection to push through. Adjust and say so. This is also where live coaching earns its keep more than a script does - see how live call coaching actually works for what that looks like in the moment, not after the call is already over.

When the honest answer is still "let me get back to you"

Making the offer on the call is a default, not a rule you force through every conversation. Slow down and follow up instead when:

You can't get three usable comps - thin data on a rural property or an unusual layout doesn't get a confident number, it gets a wrong one.
The seller mentions a condition issue you can't estimate over the phone - foundation movement, fire damage, a septic system - where a wrong repair number wrecks the whole MAO.
The deal is large enough that a same-call number carries real downside if you're off - a $600,000 property doesn't get the same speed treatment as a $140,000 one.

Telling a seller "I want to get this number right instead of fast" is a legitimate answer. What kills deals isn't occasionally needing a callback - it's defaulting to one on every call because nobody built the fast path.

Making it repeatable across a VA floor

None of this holds up if it lives in one closer's head. A velocity operation running several VAs across time zones needs the comps-pull method, the MAO formula, and the percentage-by-deal-type table written down and used the same way on every seat - otherwise the same house gets three different offers depending on who answered. Standardize the inputs (which comp tool, how many comps, the repair-cost ranges by condition tier), post the MAO percentage your floor uses by default, and review a sample of live-offer calls the way you'd review any other part of the pitch - not to catch someone lowballing, but to catch the math drifting between reps. See how to grade acquisition calls at scale for a scorecard structure that works for this specifically.

Frequently asked questions

Do I need exact comps, or is a rough number good enough on the first call? A rough, honestly-labeled working number is good enough for the first call - it's what gets the seller a real answer instead of silence. Tighten it with a full comp pull before you send a contract.

Should the MAO percentage change by seller segment? Yes. A pre-foreclosure deal on a tight legal timeline and a probate deal with no urgency don't carry the same risk, and the percentage should reflect that, not just the property condition.

What if the seller pushes back on the number immediately? Ask what number they had in mind and why, rather than re-justifying yours. Most pushback is really a request for more explanation of the math, not a rejection of the offer.

Coaching every rep to build the same number the same way - live, on the call - is exactly the kind of thing that's easy to say and hard to keep consistent once a floor grows past one person. CallVisor coaches reps in real time on the call, including the comps-to-MAO sequence, so a VA on seat six builds the same offer a founder would build on seat one.
