A month ago I had a video call with a young developer named Tomer.
He looked exhausted. A screen full of open Excel spreadsheets, dozens of open tabs in the browser.
“Ilan, I'm drowning,” he told me. “Every day I see ten deals, houses for renovation in Greece, land to build on in Romania, old buildings in Poland. It all looks ‘almost good.’ And I don't know where to start checking.”
He paused for a moment, then added:
“I feel like I'm simply choosing by gut. Sometimes because the seller sounds reliable, sometimes because the pictures are nice. And then two weeks later I discover problems I didn't see, and I feel like a kid who walked into a pool that's too deep.”
This is Tomer's problem, and it is also the problem of most developers I meet.
They were born out of passion, not out of a system.
And that passion, when it isn't managed properly, burns energy.
A professional developer must know how to identify within 10 minutes whether a deal is worth his time.
Not because he is cynical, but because his time is the most expensive capital he has.
I told him:
“Tomer, it's not that you don't know how to calculate. You're simply asking the wrong questions at the wrong stage.”
Developers at the start of the road approach a deal out of curiosity,
“How will it look?”, “How much can I earn?”, “Maybe this is my next big project?”
But an experienced developer approaches with coolness,
“Does this deal even meet my principles?”
And that is where the distinction begins.
An emotional developer looks for opportunities.
A professional developer looks for fits.
He doesn't get excited about potential yield, he examines feasibility.
Not how much beauty can be made of the property, but whether the numbers hold water.
Not what they tell him about the market, but whether the market truly wants the product he is planning.
Tomer listened quietly, then said:
“So what do you actually check when you see a new deal?”
I answered simply:
“Three things, always in the same order - time, margin, and control.”
Time - how fast the deal is supposed to end, and how many stages along the way could get stuck.
A developer who enters a project without understanding the timelines discovers too late that his profit evaporates in empty rent, in interest, or in a permit that doesn't arrive.
Margin - whether there is truly enough “meat” left in the deal.
Many developers fall in love with a pretty business plan, but forget that the profit is not created at the exit, but at the moment of purchase.
If you bought too expensive, or underestimated the execution costs, you can be a genius at marketing and still lose.
Control - whether the data you hold is real.
Many developers rely on what is sent to them, reports, presentations, estimates, without checking the source.
A professional developer doesn't fall in love with a presentation, he checks reality.
I told Tomer:
“When I receive a deal, I ask one simple question:
If I'm wrong in my assumptions, where will it fall on me?”
This is a question that makes developers stop.
Because that is where real responsibility begins.
The most successful developers I know are not smarter, they simply know how to screen fast.
They don't rush to check everything in depth.
They know how to identify within minutes whether there is anything worth continuing to check at all.
How?
Instead of focusing on finding the “perfect” deal, they build themselves a strategic filter:
- What is the investment range I'm prepared for?
- What types of property do I not touch?
- What is the minimum profit below which I don't move?
- And where do I fall again and again, and what am I doing differently this time?
Tomer was silent. Then he smiled a small smile.
“So basically you're saying I need to stop looking for deals, and start looking for a method.”
“Exactly,” I answered.
“A good deal isn't born of luck. It is the result of a system that screens out for you everything that doesn't fit.”
Two weeks later he sent me a message:
“I screened ten deals in an hour. I was left with one.
And for the first time, I'm calm.”
A developer who doesn't know how to screen lives with a feeling of FOMO.
A developer who knows how to screen lives with a feeling of control.
So the next time someone sends you a “rare opportunity,” don't rush to check plans or photographs.
First check whether it even passes your filter.
Because in development, just like in love, it's not who you meet,
it's who you choose to keep.
