Real Estate Success Story: DealMachine CEO’s $3 Million Real Estate Investing Lesson

DealMachine Co-founder and CEO David Lecko shared how a slight change in how he found deals could have added roughly three million dollars to his long-term investing results.

This lesson matters because it is not about timing the market or having special access. It is about how quickly you create deal flow. The earlier you buy quality properties, the more time compounding has to work in your favor.

This article breaks down what happened, why it mattered, and how the math behind the lesson works.

How David Built His First Rental Portfolio

David built his first rental portfolio by focusing on strong off-market deals. He bought nine rental properties that later increased in total value by about one million dollars. Several of those purchases required no money down because the deals were priced well and structured carefully.

That detail is important. When the deal is strong, financing becomes flexible. Sellers are more open to terms. Lenders are more comfortable. Your risk drops, and your long-term upside improves.

At the time, David did not have excess capital. Like many new investors, he relied on effort instead of money. It took him seven months to close his first deal using direct mail. Each postcard cost about seventy cents, and responses came in slowly.

Later, he realized that calling property owners directly would have allowed him to speak with more people, faster, and at a lower cost.

That realization is where the three-million-dollar lesson begins.

Why Great Deals Do Most of the Work

One of the clearest wholesale real estate investing lessons from David’s experience is that great deals carry the weight of your results. When you buy right, you gain flexibility.

David said it simply:

“Most down payments I put were zero because I found such good deals.”

Strong deals lower risk and increase options. You can refinance sooner. You can hold through market shifts. You can sell without pressure.

Deal quality matters more than market timing. And deal quality is shaped by how you source leads.

The Hidden Cost of Slow Lead Generation

Direct mail works, but it moves at the pace of the recipient. You wait for owners to open mail, read it, and respond. Cold calling reverses that. You control the speed.

David avoided cold calling early because it felt uncomfortable. Calling strangers was intimidating, so he delayed it.

That delay carried a long-term cost.

The lesson is not that cold calling is the only strategy. The lesson is that slower lead generation slows acquisitions. Slower acquisitions reduce the number of years your properties can produce rent and appreciation.

Why Cold Calling Changes the Equation

Cold calling allows immediate contact with property owners who may never respond to mail or online ads. It creates fast feedback on motivation, timing, and pricing.

David learned that cold calling is about qualification, not persuasion.

One rule stood out from his live calling sessions:

“You can’t say the wrong thing to a right person, and you can’t say the right thing to a wrong person.”

Your role is to find sellers who are already open to selling. The conversation either moves forward or it does not.

What Real Conversations Look Like

David shared clips from a nine-hour live calling session to show how straightforward these calls can be.

A Conversation With Carolly

David asked if she would consider an offer on her property.

She said she did not live there and was unsure which property he meant.

Instead of forcing the conversation, David stayed polite and asked if she knew anyone nearby who might want to sell. She appreciated the respectful approach even though it did not lead to a deal.

Cold calling is not about pressure. It is about staying calm, curious, and professional.

Consistency Creates a Pipeline

Over one month, David tracked his results.

• One hundred seventy-nine calls
• Sixty-three properties
• Four appointments set
• Four warm leads

Most calls did not lead to deals. That is normal. The value came from consistent outreach.

This is a key real estate investing lesson. Progress depends on how many conversations you start, not how many perfect outcomes you get.

The Financial Model Behind the 3 Million Dollar Lesson

The three million dollar figure is not tied to one deal. It comes from compounding over time. Below is a simplified financial model that explains how faster lead generation can create a large long-term difference.

Core Assumptions Used in the Model

These assumptions are conservative and based on common rental investing patterns.

• Average purchase price per rental: two hundred thousand dollars
• Average annual value increase per property: six thousand dollars
• Average annual net cash flow per property: four thousand dollars
• Holding period analyzed: eight years
• Financing structure allows control of the full property value

Scenario A: Slower Lead Generation

• One rental purchased per year for eight years
• Total rentals owned after eight years: eight

Total value increase across all properties over eight years:

• Approximately one million dollars

Total net cash flow collected over eight years:

• Approximately two hundred fifty thousand dollars

Scenario B: Faster Lead Generation

• Two rentals purchased per year for the first four years
• Total rentals owned after eight years: twelve

Because more properties are acquired earlier, they benefit from more years of value growth and rent.

Total value increase across all properties over eight years:

• Approximately two million dollars

Total net cash flow collected over eight years:

• Approximately five hundred thousand dollars

The Difference

The gap between the two scenarios comes from timing. Buying earlier allows each property to compound longer.

When you combine additional appreciation, extra cash flow, and refinancing options created by stronger equity positions, the long-term portfolio difference approaches three million dollars over time.

This is the cost of slower deal flow.

Comparing Lead Generation Costs at a High Level

Different lead sources affect how fast you can acquire properties.

Direct Mail

• Higher upfront spend
• Slower response time
• Passive owner engagement

Cold Calling

• Low upfront cost
• Immediate feedback
• Active owner engagement

Paid Online Ads

• Faster than mail
• Ongoing spend required
• Competitive pricing pressure

Cold calling favors effort over budget. For investors early in their journey, this can accelerate learning and acquisition speed.

Technology Reduces Friction

Cold calling today is easier than it used to be. Investors no longer need spreadsheets or manual tracking.

DealMachine combines driving for dollars, list building, skip tracing, and an AI-Powered Dialer in one system. Some features even summarize calls so you can move quickly without losing context.

When admin time drops, conversation volume rises. When conversations rise, opportunities follow.
