David Giraldo qualified as a lawyer before building a property deal sourcing business in London. By the time most people had heard of Property Filter, David was already one of its first 50 members. Today he runs his entire sourcing operation through the platform - every listed deal, every off-market opportunity, every client brief - all processed through Property Filter's filters, calculators, and pipeline tools before anything else happens.
David's challenge before Property Filter
Before Property Filter, David's deal-finding process had the same structural problem most investors and sourcers recognise. The information he needed was scattered. To build a complete picture of any opportunity, he had to go to Rightmove, Zoopla, and other platforms in turn - pulling data from different places and trying to assemble it into something he could act on.
For a sourcer working independently, that fragmentation was particularly costly. Without a single place to track everything, the work of managing a pipeline multiplied. Every platform had its own search logic, its own saved properties, its own way of showing what had changed. There was no single view across all of it.
"The information was dispersed. It was in different places. That was a bit challenging - having to go to different platforms."
David was also working alone. Managing a sourcing operation as a sole trader means every hour spent navigating fragmented tools is an hour not spent finding and closing deals. The administrative drag of moving between platforms was a real constraint on how much he could take on.
He had been using Rightmove and Zoopla to find and shortlist London flats, but the further he went without a system to aggregate motivated seller data and manage his pipeline in one place, the more unsustainable the process became. He needed a platform that could consolidate the whole workflow.
How David Giraldo uses Property Filter to run his sourcing business
David was among the first wave of Property Filter members. He has watched the platform develop, and throughout that time his core approach has stayed consistent: every deal goes through Property Filter, regardless of how it arrives on his desk.
For listed properties, he sets up targeted filters by postcode and strategy - finding London flats that match specific client briefs without manually trawling the major portals. For deals that come to him through other channels - contacts, investors, networks - the process is the same. He puts them into Property Filter and runs the numbers before taking any further steps.
"I use the calculators for every single deal. Even the ones that I find outside that are off market or whatever that someone brings to me, I put them in Property Filter and use the filter - everything in one place."
The pipeline management feature is central to how David tracks his progress. Rather than maintaining separate notes, spreadsheets, or documents, he uses Property Filter's pipeline to record due diligence, add comments at each stage, and move deals forward in a structured way. When he is managing multiple active opportunities, everything is visible in a single dashboard.
He has also found value in the community and training that comes with membership. Working independently, having access to property sourcing software that comes with market insight and a network of active investors is a meaningful part of the package - not just a tool he uses in isolation.
"That's the thing, right? It's everything in one place. I can have the due diligence. I can put the comments. I can use the calculator and move it from one stage to the other - and I know where I am and what I'm doing."

Feature Spotlight
David's go-to Property Filter feature: the deal calculator
David uses Property Filter's deal calculator on every opportunity that comes his way - listed or off-market. It is the first step in his evaluation process: before any deal goes further, the numbers go into the calculator. This means his entire deal history lives in one place, all assessed to the same standard, whether the deal was found on Rightmove or handed to him by another investor.
"I use the calculators for every single deal. Even the ones that I find outside that are off market - I put them in Property Filter. I use the filter, everything in one place."

Early Adopter
one of PF's first members
The overseas investor deal David describes in the interview is a clean illustration of how the platform fits into a sourcing workflow. A client based outside the UK knew exactly what she wanted: specific postcodes, specific room sizes. David set up the filter in Property Filter, found the matching properties, ran the numbers through the built-in calculator, reviewed the deal, and sent it to her. They made an offer and completed. The whole process from initial search to completion took approximately three months.
"She knew what she wanted - which postcodes and what size of rooms. So I kind of set up the filter, and then I saw it, we reviewed it, I sent it to her. I did the numbers, sent it to her, we made an offer and we completed. It took us a few months - 3 months max."
In the week of his interview, David completed three deals - something he describes with characteristic understatement as a good week. The volume is a product of having a system where nothing falls through the gaps. Every deal is tracked, every set of numbers is recorded, and the pipeline tells him exactly where each opportunity stands at any given moment.
"This week has been great because I completed three deals this week. They don't all happen at the same time and I'm like - okay, okay. These are the ones."
For sourcers and investors who want to understand what a well-organised deal pipeline actually looks like in practice, David's approach is a direct example. The platform does not change what deals are available - but it changes how efficiently every deal gets evaluated, tracked, and closed.
