How to Calculate ARV in Wisconsin (And Why It's the Most Important Number in Your Deal)
If you only get one number right in your next deal, make it this one. After Repair Value (ARV) isn't just a projection you plug into a spreadsheet — it's the number that determines your maximum offer, your loan terms, and ultimately whether the deal makes you money or costs you sleep.
Here's how to calculate it correctly, and why so many first-time investors get it wrong.
What is ARV and Why Does It Outrank Every Other Number?
ARV is what your property will be worth after renovations are complete — not what it's worth today, and not what you hope it'll be worth. Every other number in your deal flows from this one: your maximum offer, your rehab budget ceiling, your loan-to-cost, and your profit margin.
Get your ARV wrong, and everything downstream is wrong with it.
How to Calculate ARV: The Comps Method
The standard approach is to pull 3–5 recently sold comparable properties — not active listings, not what your agent thinks the market "might do." You're looking for:
- Similar square footage and bed/bath count
- Same neighborhood or a truly comparable one
- Similar finish level to what you're planning
- Sales within the last 3–6 months
Average the adjusted comps, and you have a defensible ARV.
The 70% Rule: Turning ARV Into Your Maximum Offer
Once you have an ARV, hard money lenders (RHM included) use it to calculate your Maximum Allowable Offer (MAO):
ARV × 70% – Repair Costs = MAO
Example: A property with a $300,000 ARV and a $65,000 repair budget gives you a maximum allowable offer of $145,000 ($300,000 × 0.70 = $210,000, minus $65,000 in repairs). Run your own numbers with our free Hard Money Loan Calculator.
That 30% buffer isn't arbitrary — it protects your margin against the unexpected: a longer hold, a softening market, or a repair budget that runs over.
Why Wisconsin Comps Matter More Than National Averages
A lot of ARV guidance online is written for national audiences, and it shows. Milwaukee and the broader Wisconsin market has its own rhythm — certain neighborhoods where buyers reward a full rehab, others where over-improving just adds cost without adding resale value. Comps in Waukesha County behave differently than comps in Milwaukee's central city, and a national average tells you nothing about either.
This is where local lending experience earns its keep: understanding not just what sold, but why it sold at that price.
How RHM Verifies Your ARV
We don't let borrowers guess and we don't rely on borrower estimates alone. Every deal we fund goes through a third-party ARV assessment — an unbiased evaluation that protects the borrower, the investor, and the deal itself. It's an extra step, but it's the difference between a number you hope is right and a number you can build a business on.
The #1 ARV Mistake First-Time Investors Make
Overestimating. It's almost always overestimating. Pulling comps from list prices instead of sold prices, assuming a "hot market" premium that isn't reflected in actual closings, or letting excitement about a property inflate the number. If your deal only works at an optimistic ARV, it doesn't work. Learn more about the 7 Mistakes First-Time Flippers Make.
Run Your Numbers Before You Make an Offer
A conservative, well-supported ARV doesn't just protect your deal, it makes you look more prepared to lenders, sellers, and agents alike. Before you submit your next offer, run it through our loan calculator to see where you stand. And if you want a second set of eyes on the numbers, get pre-approved and let's talk it through.
