I was scrolling TikTok at midnight — as one does when they’re studying real estate instead of sleeping — when I came across a video by Mike Ealy breaking down a 96-unit multifamily deal in Cincinnati.
I watched it three times.
Not because the numbers were complicated. Because they were so simple, and so powerful, that I couldn’t believe I hadn’t seen this framing before. He called it Millionaire Money Math. I call it the reason I’m starting to look beyond single-family rowhouses.
Let me walk you through exactly what he showed — and what it means for anyone doing multifamily real estate investing.
The Deal: 96 Units in Cincinnati for $4 Million
The property: a 96-unit apartment building in Cincinnati. Mix of one and two-bedroom units, averaging 800 square feet. Purchase price: $4 million. That’s roughly $42,000 per unit.
Current rents at the time of purchase: $900 per month per unit. That’s $1.12 per square foot.
On the surface, this looks like a standard value-add multifamily real estate investing play. Buy a building where rents are below market. Improve the units. Raise the rents. Force appreciation.
What makes this deal interesting is the math on the back end.
Multifamily Real Estate Investing Math: The $300 Rent Increase
The strategy here is straightforward. Bring rents from $900 to $1,200 per month — a $300 per unit increase. At $1.50 per square foot, that’s still competitive for the Cincinnati market.
Here’s what that does to the income:
$1,200 × 96 units = $115,200 per month $115,200 × 12 = approximately $1,382,400 per year in gross income
That’s the gross number. Now comes the part that makes multifamily real estate investing fundamentally different from single-family.
The 50/50 Rule and Cap Rate: How $1.4M Becomes $9M
In multifamily real estate investing, commercial properties are valued based on income — not comparable sales. This is the key distinction that changes everything.
Mike Ealy uses what he calls the 50/50 rule as a quick underwriting tool: assume 50% of gross income goes to operating expenses (taxes, insurance, maintenance, management, vacancy). The remaining 50% is your Net Operating Income — your NOI.
$1,382,400 × 50% = $691,200 NOI per year
Now divide that NOI by the cap rate — the rate of return investors expect in that market. At a 7.5% cap rate:
$691,200 ÷ 0.075 = $9,216,000
The building was purchased for $4 million. After stabilizing rents, it’s worth over $9 million. That’s $5 million in forced appreciation — created not by the market going up, but by operating the asset better.
That’s the Millionaire Money Math.
Why This Changes How I Think About Multifamily Real Estate Investing
I’ve been focused on Philadelphia rowhouses. Single-family. Small multifamily — duplexes, triplexes. And I still believe in that path, especially as a starting point.
But this Cincinnati example shows something that single-family investing simply can’t replicate at scale: when you raise rents on a multifamily property, you’re not just increasing cash flow. You’re multiplying the value of the entire asset by a factor determined by the cap rate.
A $300 rent increase on one rowhouse adds $300 a month to your pocket.
A $300 rent increase across 96 units — divided by a cap rate — adds $5 million to your net worth.
That’s not a small difference. That’s a different game entirely.
What This Looks Like in Philadelphia
Philadelphia has multifamily inventory. Not 96-unit buildings at $42,000 per unit — but 6-unit, 10-unit, 20-unit buildings in neighborhoods where rents are still below market and value-add opportunity is real.
The same math applies at a smaller scale. Buy a 10-unit building where rents are $200 below market. Renovate and raise rents by $200 per unit. Your NOI increases by $24,000 per year. At a 7% cap rate, that’s $342,000 in forced appreciation — on top of whatever the market does on its own.
Multifamily real estate investing rewards people who understand how commercial valuation works. And once you understand it, you can’t un-see it.

I’m Not There Yet. But I’m Studying.
I haven’t done a multifamily deal. I’m still working toward my Pennsylvania real estate license and building the foundation I need to do this right.
But videos like Mike Ealy’s Cincinnati breakdown are exactly why I spend my nights on TikTok instead of Netflix. The math is out there. The knowledge is free. The people who act on it are the ones who build real wealth.
Start with one unit. Learn the process. Understand the numbers. And keep your eyes open for the day when the scale starts to make sense.
