Precision Is Not Optional

Margins are compressed to 23%. Capital is at risk. A single miscalculation — a 10% ARV miss, an unscoped rehab line — can erase your entire profit.

88%
OF SPREADSHEETS CONTAIN ERRORS
Field audits found errors in 88% of spreadsheets examined. Every one of those errors made it to a decision.[4]
23%
GROSS FLIP ROI — LOWEST SINCE '08
Median flip ROI hit 23.1% in Q3 2025. At that margin, a 10% ARV miss doesn't reduce your profit — it eliminates it.[1]

VS
WITHOUT A SYSTEM
✗
Subjective comp weighting
No systematic method for comp age, reliability, or proximity. You pick the comps that confirm the deal you already want to do.
✗
Silent formula errors
One wrong cell reference turns a projected $40K profit into a realized $15K loss. You find out at the closing table.
✗
No circuit breakers
Nothing stops you from wiring earnest money on a deal that was never going to work.
✗
Decision drift
Same deal, different answer depending on the day. No consistent scoring means no consistent buy-box.
WITH DEALLAB
✓
Mathematically weighted ARV
Each comp receives a precise weight based on data quality (High/Med/Low) and recency (90d/180d/365d decay). No discretion involved.
✓
Deterministic, auditable logic
Every formula is hard-coded. No floating cell references, no hidden dependencies, no untracked assumptions. Fully reproducible.
✓
6 safety guards that enforce discipline
Negative profit forces NO-GO. Single-comp, wide-spread, and stale-data conditions auto-cap the score.
✓
Repeatable scoring. No drift.
Same inputs, same outputs. Monday or Friday. First deal or hundredth. A 72 is a 72.

The Math of Risk Without a System

Real estate investing is unforgiving. These are the measurable consequences of underwriting without a system — and what changes when you add one.

10%
ARV MISS = DEAL KILLER
A 10% ARV overestimate on a $300K property creates a $30K swing — enough to erase the entire profit margin at today's compressed ROIs.[1]
2 in 3
PROJECTS BLOW THE BUDGET
More than two-thirds of U.S. residential builders report budget overruns on renovation projects, per Dodge Construction Network (2024).[2]
4.5hrs
MANUAL UNDERWRITING TIME
Industry analysts estimate 4–6 hours of manual data gathering and analysis per residential deal. DealLab compresses that to under 3 minutes.[3]
23%
LOWEST FLIP ROI SINCE '08
ATTOM Data Solutions Q3 2025 Home Flipping Report: median gross flip ROI of 23.1% — the lowest since Q2 2008. One missed cost wipes out all margin.[1]
~88%
SPREADSHEETS WITH ERRORS
Field audits by Dr. Ray Panko (U of Hawaii) found errors in 88% of spreadsheets examined — formula mistakes that silently corrupt investment decisions.[4]
22%
FLIPS THAT LOSE MONEY
ATTOM data shows roughly 1 in 5 house flips result in break-even or a loss — driven primarily by poor ARV estimates and underscoped rehab.[5]

What Investors Are Saying

"The wholesale scoring engine is the first tool I've seen that actually models end-buyer MAO correctly. It stopped me from overpaying on two deals in the first month."

Active Wholesaler
30+ deals/year, Southeast market

"The 6-guard system caught a stale comp that would have inflated my ARV by $22K. That guardrail alone paid for a year of DealLab."

Buy & Hold Investor
Portfolio holder, Midwest market

"DealLab's STR analysis finally gave me clarity on occupancy viability and revenue premium vs. long-term rental. I compare all my properties through DealLab now — it changed how I evaluate hold strategy."
