For portfolio landlords

Selling up, or selling down.

Selling a portfolio is a different transaction from selling a house. The buyers are different, the property is valued on a different basis, and the way you structure the exit changes what you actually keep. Most of the money is won or lost before anything is marketed.

How portfolios are valued Talk it through

Where people usually are

Nobody sells a portfolio on a whim

It is normally the end of a long think rather than a sudden decision, and the reason matters because it changes which exit is right.

Winding down

You have done your time as a landlord and would rather have the capital than the management. The question is rarely whether to sell, but over how many tax years, and in what order.

The numbers stopped working

Higher borrowing costs and the way mortgage interest is treated for individual landlords have made leveraged portfolios much harder work than they were. Some properties still earn their place. Others are quietly subsidised by the rest.

The compliance load

Licensing, energy standards, possession rules and safety certification have all moved, and they move again. Across one property that is an afternoon. Across fourteen it is a job you did not apply for.

Consolidating rather than exiting

Selling the weakest third to pay down debt on the rest, or to buy one better asset. This is the most common version and the one least well served by ordinary estate agency.

Probate or inheritance

A portfolio arrives with an estate and the people who inherited it never wanted to be landlords. There is usually more time than executors think, and more options.

Separating partners

A jointly held portfolio being divided. Sometimes one side buys the other out, sometimes it all goes. Both need a defensible valuation before anyone argues about a number.

Valuation

Your portfolio has two different values

This is the part that catches people out, and the gap between the two numbers is usually where the whole negotiation happens.

Value one

Vacant possession value

What each property would fetch sold individually, empty, to whoever wants it most — usually an owner-occupier. Add them up and you get the biggest number.

It is also the slowest and most expensive route to reach: every property individually marketed, every tenancy ended, voids and fees on each one, and a process measured in quarters rather than weeks.

Value two

Investment value

What the portfolio is worth as an income-producing asset, valued off the net rent against a yield the buyer will accept. This is what an investor buying the lot will work from.

It is a smaller number. It arrives far faster, in one transaction, with the rent still landing until the day you complete.

The discount is real, and so is the cost of avoiding it

A bulk buyer expects to pay less than the sum of the parts, because they are taking on everything at once and pricing in whatever they have not seen. That discount is genuine and worth negotiating hard. But comparing it against the vacant possession total is the wrong comparison. Compare it against what you would actually net after months of voids, fees, continued management and the properties that turn out to be harder to sell than you assumed.

Mixed portfolios usually want a mixed answer. It is common for two or three properties to be worth selling individually with vacant possession, and for the rest to go as a tenanted block. Working out which is which is most of the value we add.

Routes out

Three ways to structure the exit

Fastest

Whole portfolio, one buyer

The lot to a single investor in one transaction. Cleanest legally, quickest to complete, and the version with the largest discount attached.

Right when speed and certainty matter more than the last few percent — a separation, an estate, or a refinancing deadline you cannot move.

Balanced

Broken into lots

Split into two or three groups by area, type or tenancy status, and sold to different buyers. Often recovers a good part of the bulk discount.

Takes longer and needs more coordination, but a well-chosen split can attract buyers who would never have taken the whole thing.

Patient

Phased over tax years

Released gradually so the gain is spread rather than landing in a single year. The rest of the portfolio keeps earning while you go.

Needs planning with your accountant before the first sale, not after. This is where the sequencing genuinely changes what you keep.

Not sure you want to sell at all?

If the problem is the workload rather than the asset, handing the management over is the cheaper answer. Full letting and management at 5%, no VAT, UK-wide. Have a look →

If the portfolio is held in a company

You may be able to sell the shares in the company rather than the properties themselves. That is a materially different transaction for both sides — different tax treatment for you, a different stamp duty position for the buyer, and much more diligence on the company itself. It is not automatically better, but it should be on the table before you assume an asset sale is the only option. Ask your accountant early.

Getting ready

What we need to give you a real number

Buyers discount for uncertainty. Every gap in the pack comes back as a lower offer or a renegotiation at week six, so it pays to gather this before anyone is approached.

The schedule

Every property, its type and size, tenure, and whether it is let, empty or owner-managed. A simple spreadsheet is fine — we would rather have it rough than wait for it to be perfect.

The rent roll

Current rent per property, arrears, review dates and how long each tenant has been in place. Long-standing tenants paying under market is an extremely common pattern and it changes the valuation.

Tenancies and compliance

Tenancy agreements, deposit protection, current EPCs, gas and electrical certificates, and any HMO or selective licence. Missing paperwork is nearly always fixable — it is far more damaging when a buyer finds it first.

Debt and charges

Lenders, balances, rates and — the one people forget — early repayment charges. An ERC across several mortgages can eat a large part of the gain and sometimes decides the timing on its own.

Ownership structure

Held personally, jointly, in partnership, or through a company. This determines the tax treatment and whether a share sale is even possible.

Condition and works

What has been done recently, what is known to be coming, and anything you would want to know if you were buying. Disclosed problems cost far less than discovered ones.

How it runs

From first conversation to completion

  1. An honest opening view

    You tell us roughly what you hold and why you are thinking about selling. We tell you what the two values are likely to look like and whether this is even the right moment.

  2. Assembling the pack

    The schedule, rent roll, compliance documents and debt position pulled into one place. Most of the time this is where problems surface, and where they are cheapest to fix.

  3. Deciding the structure

    Whole, split, or phased — chosen with your accountant in the room, because the tax treatment usually decides it rather than the marketing.

  4. Approaching buyers

    Discreetly, and only the ones plausibly able to complete. If you do not want tenants or neighbours knowing, it can be run entirely off-market.

  5. Offers and diligence

    Offers assessed on the buyer's ability to actually perform, not just the headline figure. Then their surveyors and solicitors go through everything, and the pack does its work.

  6. Through to completion

    Solicitors, lenders and tenancy handover coordinated across every property, with someone telling you what is happening before you have to ask.

Before you go further

Two things you should know about dealing with us

We know the buyers, and that cuts both ways

Finding investors for East Anglian property is the other half of what MosStone does, so there may already be a buyer for your portfolio on our list. That is the advantage of bringing it to us. It also means you should know exactly where we stand: if a buyer comes from our network you will be told who they are, what our relationship with them is, and how we are paid on the transaction, before you agree to anything. Get an independent valuation regardless. An introduction is only worth making if both sides think it was fair afterwards.

Get your accountant involved first, not last

On a portfolio sale the tax treatment routinely makes more difference to what you keep than the sale price does. Capital gains, the order and timing of disposals, whether an asset sale or a share sale suits you, and the deadlines for reporting and paying — all of it should be modelled before the first property is marketed. We are not tax advisers and will not pretend to be. What we will do is make sure the question gets asked while there is still time for the answer to matter.

Nothing on this page is tax, legal or investment advice. It describes how portfolio sales generally work and cannot take account of your circumstances. Rules on possession, energy efficiency for rented homes, and the taxation of property businesses have all changed in recent years and continue to develop — check the current position rather than relying on this page. Take independent advice from a solicitor and an accountant before committing to any route.

Straight answers

Questions portfolio landlords ask

How many properties counts as a portfolio?

There is no official threshold, and it matters less than you would think. Three properties sold together is a portfolio transaction in every way that counts — same valuation basis, same buyer type, same benefit from selling as a block. If you are thinking about more than one at a time, this page applies to you.

Do the tenants have to leave?

Usually not, and usually they shouldn't. An investor buying a portfolio generally wants the income intact from day one — sitting tenants paying reliably are an asset, not an obstacle. Ending tenancies before a sale often costs you rent and gains you nothing.

Will selling as a block cost me a lot?

You will accept less than the sum of individual vacant possession values, yes. What that discount actually costs you depends entirely on what the alternative would have netted after voids, fees, continued management and time. Sometimes selling individually is genuinely better and we will say so. Often the gap is much smaller than it first looks.

Can I sell only part of the portfolio?

Yes, and it is one of the most common things we are asked to do. Selling the weakest properties to pay down debt or fund a better asset is a strategy rather than a retreat. Choosing which ones go is the interesting part.

Can this be kept quiet?

Yes. Portfolio sales are frequently run entirely off-market, with no listings and no boards. Tenants, neighbours and competitors need not know anything until it is done. If discretion matters, say so at the start and the whole approach changes.

What will you charge?

It depends on the size of the portfolio and how much of the process you want us running. It is agreed in writing before any work starts, never deducted as a surprise later. Ask on the first call and you will get a straight number.
