How to Calculate Your Max Offer

The approach depends on your investment strategy. Both work backwards from your target return to find the ceiling price.

Flip / BRRRR Strategy

  1. 1

    Start with After Repair Value (ARV)

    What the property will be worth after renovations.

  2. 2

    Subtract all costs

    Repairs, buying closing costs, selling costs & commissions, and holding costs for the rehab period.

  3. 3

    Subtract your target profit

    What's left is the most you can pay and still hit your return target.

Buy & Hold Strategy

  1. 1

    Set your income targets

    Choose your minimum cap rate and cash-on-cash return thresholds.

  2. 2

    Reverse-engineer the price

    The calculator finds the max price where both your cap rate and CoC targets are met.

  3. 3

    Take the conservative answer

    Uses the lower of the two approaches, then subtracts repair costs to get your max purchase price.

Flip MAO Formula

ARV − Costs − Repairs − Profit

After Repair Value minus all project costs, repairs, and your target profit margin.

70% Rule (Quick Check)

ARV × 70% − Repairs

A rough flip filter. Our calculator gives a more precise MAO based on your actual costs.

Rental MAO Formula

min(NOI ÷ Cap Rate, CoC Price) − Repairs

The lower of cap-rate-derived and cash-on-cash-derived prices, minus rehab costs.

Why You Need to Know Your Max Offer Before Negotiating

Most failed real estate investments share one thing in common: the investor paid too much. Calculating your maximum allowable offer before making a bid ensures every deal meets your return requirements — no matter how competitive the market gets.

When to Use Each Strategy

Flip / BRRRR

Use for properties you plan to renovate and either resell or refinance. The ARV-based approach accounts for rehab timelines, holding costs during construction, and your target profit margin as a percentage of the after-repair value.

Buy & Hold

Use for rental properties where you care about ongoing income yield. The calculator reverse-engineers your max price from both cap rate and cash-on-cash return targets, factoring in financing terms to give you the most conservative (safe) answer.

Common MAO Mistakes

  • Underestimating repair costs — always get contractor bids before committing to a number.
  • Forgetting holding costs — every month of rehab eats into your profit. Budget for delays.
  • Using the 70% rule as gospel — it doesn't account for your specific closing costs, holding period, or market conditions.
  • Ignoring financing costs in rental analysis — a deal can look great on cap rate but fall apart after debt service.

Frequently Asked Questions

What is a maximum allowable offer (MAO)?

MAO is the highest price you should pay for an investment property while still hitting your target return. It works backwards from your desired profit (flips) or income targets (rentals) and subtracts all costs — repairs, closing costs, and holding expenses — to find the ceiling price.

What is the 70% rule in real estate?

The 70% rule is a quick flip formula: MAO = ARV × 70% − Repair Costs. If a home’s after-repair value is $300K and it needs $40K in work, the 70% rule says pay no more than $170K. It’s a rough filter — our calculator gives you a more precise MAO based on your actual cost structure.

How does the rental MAO calculation work?

For buy-and-hold deals, the calculator reverse-engineers your maximum price from two angles: (1) what price gives you your target cap rate, and (2) what price gives you your target cash-on-cash return after financing. It uses the lower (more conservative) of the two as your MAO.

Should I always offer the MAO price?

MAO is your ceiling, not your target. In competitive markets you may need to offer close to it, but ideally you negotiate below MAO to build in a margin of safety. The further below MAO you buy, the more profit buffer you have if costs run over or the market softens.

What costs does the flip MAO include?

The flip calculation accounts for repair costs, buyer closing costs, seller closing costs and commissions, monthly holding costs (insurance, taxes, utilities, loan payments during rehab), and your target profit margin. All are subtracted from the after-repair value to find your max purchase price.
