Quantitative Real Estate Analyst · Math & Physics

30-Minute Paid Diagnostic Session

Your real estate portfolio —
mathematically exposed
in 30 minutes.

Most investors with $1M+ in real estate have never seen the numbers that actually matter — portfolio-level IRR, true correlation between holdings, Sharpe ratio, stress test results. This session changes that.

The Problem

You have built a portfolio.
But have you ever seen it
through a mathematical lens?

Most real estate investors — including physicians, engineers, and business owners with $1M–$10M in property — make portfolio decisions based on gut instinct, broker advice, and individual deal metrics. Individual deal metrics tell you almost nothing about how your portfolio behaves as a system.

—Can you state your portfolio-level IRR — not individual deal IRR — right now?

—Do you know the true correlation between your properties and what it means for your real diversification?

—Have you ever calculated the Sharpe ratio of your entire portfolio?

—What happens to your cash flow in a recession with 15% vacancy and a 200bps interest rate spike?

—Is your portfolio sitting on the efficient frontier — or are you leaving return on the table?

How It Works

A working session.
Not a sales call.

Before the Call — What Happens First

After booking you complete a detailed intake form covering your portfolio basics and 12 diagnostic questions. I then spend 1–2 full days analyzing your specific data — running your numbers through my quantitative models before we ever speak.

You do not arrive to a discovery session. You arrive to a prepared diagnosis of your actual portfolio.

Day 1 — Build Your Picture

Input & Core Calculations

Input all your property data into quantitative models
Calculate your true portfolio-level IRR
Build your correlation matrix across all holdings
Calculate your portfolio Sharpe ratio
Map geographic and debt concentration
Identify your 3 biggest mathematical problems

Day 2 — Deep Analysis

Models & Diagnosis

Monte Carlo simulation on your specific portfolio
Recession scenario stress test
Interest rate spike stress test
Efficient frontier positioning
Prepare your personalized call diagnosis
Know your numbers better than you do before we meet

After Payment — Immediate

Complete Your Intake Form

You complete the portfolio intake form — data across up to 8 properties plus 12 diagnostic questions answered in writing. You then select from the next available Wednesday, Friday, or Saturday slot — typically 2 to 5 days away. This window is intentional. It gives me adequate time to run a thorough quantitative analysis of your specific portfolio before we meet.

1–2 Days Before Your Call

I Analyze Your Portfolio

I spend 1–2 full days running your specific numbers through my models — correlation matrix, Sharpe ratio, Monte Carlo simulation, stress tests, efficient frontier positioning. I arrive knowing your portfolio mathematically before you say a word.

Minutes 0 – 5

Quick Confirmation

I confirm the key details from your intake form are still accurate. No time wasted on information that should have been gathered already.

Minutes 5 – 25

Your Mathematical Diagnosis

I walk you through exactly what the math reveals about your specific portfolio — concentration risks, correlation exposure, optimization gaps, and where your risk-adjusted return is being silently eroded. Specific numbers. Your portfolio. Not generic advice.

Minutes 25 – 30

One Honest Question

One clear question. One honest answer. You leave with genuine mathematical clarity about your portfolio regardless of what you decide to do next.

A Preview

The questions most real estate
investors have never been asked.

These are drawn from the actual intake form you complete after booking. If you cannot answer most of them — that is precisely why this session exists.

Question 01

"What is your portfolio-level IRR — not your best deal's return, but across all holdings combined?"

Question 02

"Have you calculated the correlation between your properties? Are they actually diversified or just spread out?"

Question 03

"What is the Sharpe ratio of your real estate portfolio? How does it compare to other asset classes you hold?"

Question 04

"If interest rates rose 300 basis points tomorrow, what happens to your debt service coverage across every property?"

Question 05

"Where does your portfolio sit on the efficient frontier? How much return are you leaving on the table right now?"

Question 06

"Have you run a Monte Carlo simulation on your portfolio? What does your IRR distribution actually look like?"

Is This Right For You?

This session is designed for
a specific type of investor.

This is for you if —

✓ You have a real estate portfolio worth $1M or more
✓ You are analytical by nature — physician, engineer, lawyer, or business owner
✓ You suspect your portfolio is not optimized but have no framework to verify it
✓ You want rigorous mathematical analysis — not gut feel advice
✓ You make decisions based on evidence not emotion
✓ You understand that $197 is trivial against a suboptimal $2M+ portfolio

This is not for you if —

✗ You are just getting started with your first property
✗ You want generic advice available for free online
✗ You are not willing to share honest numbers about your portfolio
✗ You prefer intuition-based investing over quantitative frameworks
✗ You are looking for a conversation rather than a rigorous analytical session

Who You Are Working With

Math and physics applied
to real estate investing.

Most real estate advice comes from people who know deals. I come from a background in mathematics and physics — disciplines built entirely around modeling complex systems, quantifying uncertainty, and finding optimal solutions under constraints.

Real estate portfolios are complex systems. They have correlation, entropy, flow dynamics, and optimization surfaces — most investors just never see them that way. My work is to make those invisible forces visible, quantifiable, and actionable.

Through Viregenix LLC I apply the same quantitative frameworks that institutional investors — pension funds, family offices, private equity — use as standard practice. Now applied to individual and mid-market portfolios that have never had access to this level of analysis before.

Your portfolio deserves
mathematical certainty.

Limited to 2 calls per week across three available slots — Wednesday, Friday, and Saturday. After payment you complete the intake form and select your slot. Your call will typically be 2 to 5 days away. That window is intentional — I spend the 48 hours immediately before your call running your specific portfolio through my quantitative models so I arrive fully prepared. You will receive your personalized diagnostic document 30 minutes before we meet.
