If you’ve spent five minutes on BiggerPockets or YouTube, you’ve heard the golden commandment of real estate: “Thou shalt not pay more than 70% of the ARV minus rehab.”
It’s a beautiful, simple formula. But in 2026, with tight inventory and stubborn interest rates, finding a deal at 70% feels like hunting for a unicorn in a haystack.
Is the rule dead? Or are investors just getting reckless?
The Brutal Reality of the 70% Rule
The 70% rule was designed for a different era. Its goal is to protect your downside:
- 15% to 20% for the bank’s equity (to ensure a full cash-out refinance).
- 10% to 15% for closing costs, holding costs, and a safety buffer.
The Problem: In today’s competitive markets, wholesalers are selling deals at 80% or 85% of ARV. If you stick strictly to 70%, you might never buy a house again.
The Shift: From 70% to the “Cash-Left-In-Deal” Model
Experienced BRRRR investors have stopped obsessing over the 70% rule and started focusing on Return on Capital.
If you buy at 78% of ARV, you will likely leave some cash “trapped” in the deal after the refinance. And that’s okay—if the cashflow justifies it.
Example: The “New” Math
- ARV: $250,000
- Purchase + Rehab: $195,000 (78% of ARV)
- Refinance (75% LTV): $187,500
- Cash Trapped: $7,500
In the old days, this was a “failed” BRRRR. In 2026, if that duplex nets you $500/month in cashflow, your Cash-on-Cash ROI is 80% ($6,000 annual profit / $7,500 invested).
Compare that to the 8% return of the S&P 500. The BRRRR still wins by a landslide.
🚨 The Danger of “Overpaying”
The reason the 70% rule is “safer” isn’t just about profit—it’s about Refinance Risk.
If you buy at 85% of ARV and the appraisal comes in 5% low, you might need to bring $20,000 to the closing table just to get your long-term mortgage. This is where most beginners go bankrupt.
Don’t fly blind. You need to know exactly how much cash you are risking at different appraisal scenarios.

How to Pivot in 2026
- Target “Value-Add” Utilities: Don’t just paint. Look for properties where you can add a bedroom or a bathroom (ADUs). This “manufactures” an ARV that can bring an 80% buy back down to a 70% value.
- Negotiate the “Buy”: With higher rates, sellers are more willing to offer Seller Concessions. Use them to buy down your interest rate and save your monthly cashflow.
- Analyze Every Scenario: The difference between a 70% and a 75% rule is thousands of dollars.
Verdict: It’s not dead, it’s evolved.
The 70% rule is still the gold standard for maximum safety, but the “75% to 80% Rule” is the reality for maximum growth in 2026.
The secret isn’t following a static rule; it’s mastering the spreadsheet.
