Practical guidance for people considering or building a buy-to-let portfolio, helping you work through the numbers, assess potential acquisitions, and make more informed decisions as your portfolio develops.
Arrange a conversation →A structured review of your objectives, available capital, financing assumptions, and investment priorities, helping you establish what a realistic buy-to-let strategy looks like before individual properties start driving the decision.
When a real property is on the table, the assumptions are reviewed before capital is committed. Purchase costs, expected rent, financing, operating costs, initial works, and total cash required are worked through and stress-tested against the wider portfolio strategy.
For clients who want an experienced sounding board while they act – the relationship most people are describing when they say they are looking for a mentor. Regular conversations, acquisitions reviewed as they arise, and assumptions revisited as circumstances change.
For people with capital available who understand the broad principles of buy-to-let but want help applying them to their own position.
For landlords who already own one or more properties and want an experienced second opinion on where to go next.
For landlords who want to review how their existing properties are performing and whether anything should change.
A short introductory conversation, free of charge, to understand what you are trying to achieve, where you are in the process, and whether working together makes sense. No obligation either way.
The Portfolio Strategy Review takes stock of where you are now and sets the framework from there: what to look for, what the numbers need to support, and what to avoid.
As potential acquisitions come up, the Acquisition Sense-Check tests the numbers, assumptions, and risks against the strategy before a decision is made.
For clients who want continued support, Ongoing Investor Advisory provides a regular sounding board as opportunities, circumstances, and priorities change.
Collett Advisory exists because I know what it is like to understand the principles of property investment and still have nobody experienced to call when a real decision needs making.
I began investing in my early twenties with no family background in property or finance, and no mentor. I built a buy-to-let portfolio across Berkshire, Derbyshire, and South Yorkshire through a mixture of personal and limited-company ownership, assembling a team, assessing hundreds of listings, and travelling to viewings. I spent a long time looking in Nottingham without buying there because the competition made the numbers stop working. It took around forty offers to secure six properties.
Some decisions worked well. Others I would approach differently today, particularly around ownership structure, changing tax circumstances, and refurbishment risk – and the importance of testing an exit as carefully as an acquisition. The purpose of Collett Advisory is not to persuade anyone to invest, but to help clients challenge their assumptions before capital is committed.
Alongside my own portfolio, I have worked professionally in landlord property management. Collett Advisory provides client-side project management to a private family office, supporting substantial residential, commercial, and private estate projects. That professional experience also brings a practical understanding of construction, refurbishment, cost, and delivery risk to the investment advisory work.
That is what Collett Advisory is for: the considered, experienced sounding board I wish I had when I started.
Collett Advisory provides client-side project management for private clients, estates, and commercial owners, supporting projects from early planning and procurement through to delivery oversight.
The role is to represent the client's interests throughout: developing the brief, testing costs before they are committed, and keeping the project honest on budget and programme.
Typical instructions include residential refurbishments, private estate projects, commercial property works, and other projects where the client wants experienced oversight of consultants, contractors, cost, and programme.
Residential flat refurbishment, London. Client-side management of a leasehold project requiring landlord consent, statutory requirements, and coordination of multiple consultants, where access, permitted working hours, and neighbouring occupation shaped the programme as much as the works themselves.
“Adam broke everything down in a very practical way, from likely works and contingency to rental demand, financing, and what could go wrong. It felt balanced rather than just encouraging me to go ahead.”
“Adam worked through what my capital could realistically support, what the income might actually look like, and where the risks sat. He was clear about the limits of his own advice and what needed a qualified specialist.”
Collett Advisory provides property investment analysis and decision support. It does not provide regulated financial, mortgage, legal, or tax advice, and does not advise on whether property should be chosen ahead of pensions, ISAs, other investments, or equity release. Where specialist advice is required, clients should consult appropriately qualified professionals.
Whether you are considering what your capital could realistically do, reviewing a potential acquisition, or deciding what comes next for an existing portfolio, start by telling me where you are now and what you are trying to achieve.
Every enquiry comes to me directly, and advice is shaped around the specific property, project, or investment decision involved.
You will usually receive a response within 1–2 working days. If your enquiry is time-sensitive, please make that clear in your message.
