About OGKinvest

Experience you
can build on.

Why a UK-based property investor and Turkish architecture graduate founded a different kind of advisory: one that explains rather than sells.

Our story

OGKinvest was founded on a simple observation: international buyers approaching the London market are rarely given a clear, honest picture. The information tends to come from people paid to sell, and the language tends towards promises rather than explanations.

Our founder, Özgün Karslı, approached London property from a different starting point: an architecture graduate who worked on large-scale housing projects in Türkiye, on site as well as at the drawing board, then came to London in 2019 for the Architectural Design MArch at The Bartlett, UCL and became a property investor here. That meant learning the market the hard way: not from a brochure, but by refurbishing a building in the North West, then buying, financing, letting and managing new-build flats in and around London.

Learned the hard way.
Not from a brochure.

First-hand, not second-hand

Our founder has completed the process,
not just read about it.

Purchased UK investment properties and new-build apartments directly from developers.
Arranged mortgages and dealt with lenders and brokers.
Instructed solicitors and worked through conveyancing, contracts and completion.
Handled lettings, tenants and ongoing property management.
Managed refurbishment, snagging and the realities of owning property remotely.
Assessed every purchase as a buyer first: what it costs to hold, whether it will let and what the lease says.
Both sides of the same journey

I rented here
before I bought here.

In 2019 I came to London for a master's at UCL and rented with friends, the way most students do. Looking back, buying was at least worth considering, and nobody put those numbers in front of my family. Later I did buy: new-build flats directly from developers. I handled the conveyancing, the mortgages, a refurbishment, the lettings and the day-to-day management myself.

So when a family asks which area suits a student at UCL, King's or LSE, what a purchase will really cost, or whether to rent or buy at all, the answer comes from having done both. Our guide to buying near a university is where that starts. And because I financed and let these flats through my own companies, I can also tell you what comes after the keys: the mortgage, the tenants and the running costs.

Özgün Karslı, founder

"Our measure of success is not how quickly a buyer commits, but how confident they feel about the decision they make, including a confident decision to wait.

What we set out to do

Filter, don't promote.
Explain, don't sell.

We built OGKinvest to help Turkish and international buyers make informed decisions about London property: calmly, transparently and on their own terms.

We filter rather than promote. We explain rather than sell. And we are open about how we are paid and where our role ends.

Our founder has personally bought new-build flats of the kind discussed on this site. That is why we are open about how we are paid, and why we will say “not this one” when we mean it.

A clear note on our role

We are a property introduction and advisory business. We are not regulated financial advisers, mortgage advisers, solicitors or tax advisers, and nothing on this site is advice of that kind. We help you understand the landscape and connect you with the right qualified professionals for the decisions that require them.
