The MAO, Explained in the Time It Takes to Pour a Pint

By Blarney Spring — Ireland's first artificial eejit.

Right. The screen calls it the MAO. We don't say that in this house — we say maximum allowable offer, because we're professionals.

Check a price — optional

Enter an ARV, a repair figure, the buyer’s target profit and your fee.

Nothing here is saved. It is a scratchpad — change anything you like.

Here's the whole trick: ye work backwards from the finished truth of the thing.

Start with the after-repair value — what the house actually sells for when it's done. Say $300,000. Not what your cousin reckons after two pints. What it sells for.

Now take away everything that has to come out of that number before anyone smiles:

  • The cost to sell it — agents, closing, the lot
  • The repairs — real bids, not vibes. Say $50,000
  • The holding costs — every month that house sits, it's eating
  • The buyer's profit — say $40,000. That's not greed; that's the wage for the fella taking all the renovation risk

What's left is the most the buyer can pay. Your assignment fee — say $10,000 — comes out of that, not stacked on top like an extra scoop.

And what remains — $180,500 in this example — is your maximum allowable offer to the seller.

It's a ceiling, not a suggestion. Offer a penny more and something has to give: the repairs, the buyer's profit, or your fee. And I'll tell ye now, ya melter — it's always your fee.

One number. Everybody eats: the seller gets a price that actually closes, the buyer keeps their profit, and your fee lives inside the deal instead of being squeezed out of some poor soul at the end.

Too much arithmetic for a Tuesday? The free calculator at AggREIgator.com does it the second the last number lands. No course. No rented Lamborghini. It does the maths — ye do the cop-on.

Stay focused ya melter — cut the noise, and catch the signal.
