To calculate your Maximum Allowable Offer (MAO) in real estate, you need to work backward from the property's After Repair Value (ARV), accounting for your end buyer's desired profit, estimated rehab costs, and your own wholesale fee. The core formula for how to calculate maximum allowable offer real estate is straightforward, but its accuracy hinges on precise inputs. Forget the fluff; here's the equation you need:

This formula ensures there's enough meat on the bone for your cash buyer to make a profit after they acquire, renovate, and resell the property, while also securing your fee for finding and facilitating the deal. Let's break down each component.

The Core Formula: How to Calculate Maximum Allowable Offer Real Estate

Your MAO isn't just a number you pull from thin air; it's a strategic calculation designed to make your deal attractive to a cash buyer. Here's what each part of the formula represents:

Breaking Down the MAO Components for Accuracy

The formula is simple, but the devil is in the details of each input. Skimp on these, and your MAO will be worthless.

Accurate ARV: The Foundation of Your Offer

Your ARV must be based on solid data. Don't guess. Use:

Kernalite can help you organize property data and notes from your off-market deal hunting, making it easier to track and compare potential comps as you build your ARV estimates.

Estimating Rehab Costs: No Room for Wishful Thinking

This is where many wholesalers stumble. A rough per-square-foot estimate is a starting point, but a detailed breakdown is better. Consider:

If you're new, walk through properties with experienced contractors or mentors to get a feel for costs. Don't rely on online calculators alone.

Investor's Discount Percentage: Appealing to Your Buyers

The "Rule of 70" (70% of ARV minus repairs) is a widely accepted benchmark. It provides a healthy margin for your end buyer, covering their purchase costs, rehab, holding costs, and profit. If your market is extremely hot and competitive, you might stretch to 75%, but proceed with caution. Your goal is to make the deal irresistible to your cash buyers, not just break even. Remember, their profit is your bread and butter.

Your Wholesale Fee: Know Your Worth

This is your compensation for the legwork. A typical fee is $5,000 to $15,000, but it can vary based on the deal's size and complexity. Don't be greedy, but don't undervalue your time and expertise either. A good deal for everyone involved is a sustainable deal.

A Practical Example: Putting the MAO Formula to Work

Let's run through a scenario:

Now, apply the formula:

MAO = (ARV x Investor's Discount Percentage) - Estimated Rehab Costs - Your Desired Wholesale Fee

MAO = ($300,000 x 0.70) - $50,000 - $10,000

MAO = $210,000 - $50,000 - $10,000

MAO = $150,000

In this example, your Maximum Allowable Offer to the seller for 123 Main Street is $150,000. This is the highest you can offer while still leaving enough room for your buyer to profit and for you to earn your fee.

Beyond the Numbers: Strategic Considerations for Your Offer

While the formula provides the objective ceiling, real estate is rarely purely objective. Factor in these strategic elements:

Common questions

What is the Rule of 70 in real estate wholesaling?

The Rule of 70 is a guideline stating that a wholesaler should offer no more than 70% of a property's After Repair Value (ARV) minus the estimated repair costs to ensure enough profit for the end buyer.

Why is accurate ARV crucial for MAO calculations?

An accurate After Repair Value (ARV) is the foundation of your MAO. Overestimating ARV leads to overpaying, while underestimating can cause you to miss out on profitable deals.

How does seller motivation impact my Maximum Allowable Offer?

Highly motivated sellers are often willing to accept a lower offer for a quick, hassle-free sale, which can allow you to make a more attractive MAO while still securing your profit.
