Selling vs refinancing a completed development: running the numbers
At practical completion a developer holds finished units and a maturing development loan, and has to decide whether to sell the scheme or keep it and refinance. This guide runs that decision as a numbers problem: how much cash each route frees after real costs, the income a held scheme produces, and where the developer stands three years on.
Selling a completed development turns the scheme into a single lump of cash now, once agency, legal, incentive and finance costs come out, and ends the developer's exposure to it. Refinancing keeps the units and swaps the development loan for long-term investment debt, which releases less cash today but adds rental income and any capital growth on the units retained. The right answer is a cash calculation rather than a rule: how much each route frees after costs, what annual income the held units would net, and the position after three years. We arrange the finance behind either route, including the exit bridge that buys time to decide, and nothing here is tax advice or an offer of finance.

Sell or refinance seen as one cash-flow question
The choice between selling and refinancing a completed development is a question about where the money goes and when. Selling converts the whole scheme into cash in a single window: the units are sold, the development loan is cleared, and the surplus lands as a one-off, usually within a marketing period of twelve to eighteen months. Refinancing does the opposite: it keeps the units, repays the development loan out of new long-term debt, and hands the developer a smaller cash release now in exchange for rental income and continued ownership.
Framed that way, the decision becomes three numbers rather than a matter of strategy in the abstract. The first is the cash each route frees after every real cost has come out. The second is the annual net income a held and let scheme would produce once its new mortgage is serviced. The third is the position after three years, once a sold scheme's cash has been redeployed and a held scheme has collected rent and any growth. Set those three side by side and the answer for a given scheme is usually clear.
| Question | Sell the scheme | Refinance and hold |
|---|---|---|
| Cash now | High: sale proceeds after costs | Lower: the loan above the debt |
| Income after | None from this scheme | Net rent after the mortgage |
| Sized on | Open-market sale price of each unit | Investment value capped by rental cover |
| Keeps the upside | No, the units are gone | Yes, capital growth on retained units |
| Exposure | Ends at completion of sales | Continues as a landlord |
The sell route and its true costs
Selling is the route most developers model first, because it realises the profit built into the scheme in one clean move: the units are marketed, sales are agreed, and completions repay the development loan and release the balance. What catches developers out is the gap between the gross development value on the appraisal and the cash that actually reaches the bank. Several costs sit in that gap, and none of them are optional.
Agency fees are the first, usually a percentage of each sale price plus VAT, and on a multi-unit scheme they add up quickly. Conveyancing is a per-unit cost. Then come the buyer incentives a real sales programme needs to hit its timescale: paid stamp duty, upgraded specifications, part-exchange or straightforward price adjustments when the market is soft. Finally there is the cost of carry, because the development loan or the exit bridge that replaces it keeps accruing interest across the whole sales period, so a slower market is not just a delay but a direct cost that eats into the surplus.
A gross development value is a headline, not a net figure. On an eight-unit scheme, agency, legal costs, incentives and sales-period finance can together take a meaningful slice of the top line before the development loan is even repaid. The realistic number to plan around is net proceeds after all of those, and it is that figure, not the GDV, that should sit opposite the refinance option in any comparison.
The refinance route, rental cover and what surveyors do
Refinancing keeps the units and replaces the development loan with long-term investment debt. For a developer sitting on a block of finished flats, that typically means a buy-to-let mortgage on each one, or, where several units are involved, a single portfolio buy-to-let facility covering the whole scheme. The rental income services the debt, the development facility is redeemed in one move, and any loan above the debt is released as cash. Where a scheme is built to rent from the outset, this is simply the planned exit.
The size of the refinance is set differently from a sale. A buy-to-let lender sizes the loan against the investment value of the let asset and then caps it with a rental cover test, the interest cover ratio, or ICR. The ICR is the multiple by which the rent must exceed the mortgage interest, indicatively 125 percent for a limited company and higher for individual higher-rate taxpayers, tested at a stressed rate above the pay rate. On many schemes it is this cover test, not the loan-to-value ceiling, that sets the maximum loan, because the rent runs out before the value does.
Brand-new units also meet a surveyor's judgement on rental value and on the basis of valuation. A block refinanced as an investment is often assessed on a bulk or portfolio basis, which can sit modestly below the sum of the individual open-market sale prices, because the buyer of the whole block is an investor rather than eight separate owner-occupiers. New-build rents are checked against genuinely comparable local lettings rather than an asking figure. The practical effect is that the investment value driving the refinance can be a little below the GDV that would drive a sale.
Take eight flats letting at 1,400 pounds a month each, so 134,400 pounds of gross rent a year. At an interest cover ratio of 125 percent tested near 6.5 percent, the affordable interest is about 107,500 pounds, which supports a loan of roughly 1.65 million pounds. That figure can be well below 75 percent of the investment value, so the rent, not the value, sets the ceiling. All of these numbers are for illustration and are not an offer of finance.
A worked comparison on the same eight-unit scheme
The clearest way to see the trade-off is to run one scheme both ways. Take an eight-unit residential block with a gross development value of 2.8 million pounds, 350,000 pounds a unit, a development loan of 1.5 million pounds to repay, and an achievable rent of 1,400 pounds a month per flat. The table below sets the sell route against the refinance-and-hold route on the same numbers. Every figure is illustrative, rounded, and not an offer of finance; a real case would be modelled on its own costs, rents and valuations.
| Metric | Sell all eight units | Refinance and hold |
|---|---|---|
| Basis of value | Sale price 2,800,000 | Investment value 2,660,000 |
| Gross release | 2,800,000 sale proceeds | 1,650,000 new loan (cover-capped) |
| Costs to execute | Around 100,000 agency, legals, incentives | Around 45,000 valuation, arrangement, legals |
| Sales-period finance | Around 90,000 across the marketing period | Not applicable |
| Development loan repaid | 1,500,000 | 1,500,000 |
| Cash released now | Around 1,110,000, taken once | Around 105,000 |
| Annual net income | None from this scheme | Around 23,600 after mortgage and running costs |
| Position after 3 years | Cash redeployed into the next scheme | About 176,000 taken plus retained equity and growth |
The pattern is the one every developer recognises once it is on paper. Selling frees far more cash immediately, roughly 1.1 million pounds here, which suits a developer who needs capital for the next scheme or wants a clean end to the exposure. Refinancing frees only about 105,000 pounds today, but adds around 23,600 pounds of net rent a year and keeps every unit, so its retained capital and future growth belong to the developer rather than to eight buyers. Over three years the sold cash has to earn its keep elsewhere, while the held scheme compounds rent and value against a static debt.
Tax touchpoints to raise with your accountant
Tax often moves the answer, and it is the part of this decision where a developer should take proper advice rather than a rule of thumb. We do not give tax advice and nothing here is tax advice. What follows is simply the list of touchpoints worth putting in front of an accountant early, because the treatment can differ sharply between selling and holding, and because intention at the outset can shape it.
- Trading versus investment intention: a scheme built to sell is typically trading stock, while a decision to hold and let can move units towards investment treatment, which changes how profits and gains are taxed.
- Capital gains versus income treatment: a sale of trading stock tends to be taxed as income or trading profit, whereas a genuinely held investment asset may fall under capital gains treatment on a later disposal.
- Stamp duty land tax on transfers: moving units into a holding company or between connected parties can be a chargeable transfer for SDLT, so restructuring before a refinance carries a cost to count.
- VAT position: the treatment of new residential build, any commercial element and professional fees is not uniform, and an assumption carried from the build phase can be wrong at exit.
- Timing and year end: unsold stock and the point at which a hold decision is formalised can affect which tax year a profit or gain falls into.
None of these should be guessed. They belong in a numbers-first comparison because a tax bill is a real cash cost, and a route that looks better on the pre-tax figures above can lose that lead once the tax on each is modelled. An accountant who sees the plan before completion, rather than after, can often structure the exit so the chosen route is not undercut by an avoidable charge.
The hybrid: sell some units, refinance the rest
The sell-or-refinance choice is rarely all or nothing. A common and often sensible answer on a multi-unit scheme is to do both: sell enough units to clear the development loan and take some profit, then refinance the remaining units onto a buy-to-let or portfolio facility and hold them for income. This splits the difference between the two columns above, freeing a useful lump of cash while retaining a stake in the scheme's future value.
The hybrid also eases the constraints that bind each pure route. Selling a portion reduces the loan the retained units carry, which can lift them clear of the interest cover ceiling that would otherwise cap the refinance. Holding a portion means the developer is not forced to discount the final, hardest-to-sell units into a soft market to hit a loan maturity. The right split is a modelling exercise on the specific scheme: how many units to sell to clear the debt and fund the next project, and how many to keep for the income the numbers support.
Using an exit bridge to buy time to decide
Not every developer has to choose at the moment the development loan matures, and that is where an exit bridge earns its place. A development exit bridge is a short-term facility taken out at or close to practical completion to clear the maturing development loan; it is measured against gross development value, indicatively as high as 70 to 75 percent, and because the construction risk has already gone it undercuts the development finance it takes over. It gives a sales window of typically twelve to eighteen months without a decision being forced by a hard maturity date.
That breathing space is valuable precisely because sell or refinance is a numbers question, and the numbers get clearer with a little time. Under an exit bridge a developer can test real sale prices on the first units, let a few flats to establish genuine achievable rents, and watch the local market before committing capital either way. If sales move well the bridge clears through completions; if the case for holding firms up, the bridge is instead cleared by a refinance onto buy-to-let or term debt. We source and put in place both that bridge and the take-out sitting behind it, matching each to whichever funder has the appetite for the finished scheme. As an arranger and introducer rather than a lender, we note that every figure on this page is for illustration only and is not an offer of finance.
Selling vs refinancing a completed development: running the numbers: common questions
Does selling or refinancing put more cash in my pocket right now?
Selling almost always frees more cash immediately, because it realises the full sale price of every unit less costs, whereas a refinance releases only the new loan above the development debt. On the illustrative eight-unit scheme above, selling might free around 1.1 million pounds once, while a refinance frees around 105,000 pounds now but adds annual rent and keeps the units and their future growth. More cash today is not automatically the better outcome. All the numbers here are for illustration and are not an offer of finance.
What are the true costs of selling a completed development?
Beyond the headline sale prices, a real sales programme carries agency fees at a percentage plus VAT, conveyancing on each unit, and buyer incentives such as paid stamp duty, upgrades or price adjustments to hit the timescale. On top of those sits the cost of carry, because the development loan or the exit bridge that replaces it keeps accruing interest across the whole marketing period. The number to plan around is net proceeds after all of these, not the gross development value.
What is an interest cover ratio and how does it cap a buy-to-let refinance?
The interest cover ratio, or ICR, is the multiple by which the rent must exceed the mortgage interest, indicatively 125 percent for a limited company borrower and higher for individual higher-rate taxpayers, tested at a stressed rate above the actual pay rate. A lender takes the rent, divides it by the ICR and the stress rate, and that sets the maximum loan. On many schemes the rent runs out before the loan-to-value ceiling does, so the cover test, not the value, decides how much a refinance releases.
Will a surveyor value brand-new units lower for a rental refinance than for a sale?
Often a little lower, because a block refinanced as an investment can be assessed on a bulk or portfolio basis rather than as separate owner-occupier sales, and that basis can sit modestly below the sum of the individual open-market prices. New-build rents are also checked against genuinely comparable local lettings rather than an asking figure. The practical effect is that the investment value driving a refinance may be a touch below the GDV that would drive a sale.
What tax should I check before deciding to sell or refinance?
The main touchpoints to put to an accountant are trading versus investment intention, whether a disposal is taxed as income or as a capital gain, any stamp duty land tax on transferring units into a holding structure, and the VAT position on new residential and any commercial element. Timing around the tax year end can matter too. We do not give tax advice, and the point of raising these early is that a tax bill is a real cash cost that can change which route wins on an after-tax basis.
Can I sell some units and refinance the rest?
Yes, and it is often the most practical answer on a multi-unit scheme. Selling enough units to clear the development loan and take some profit, then refinancing the remaining units onto a buy-to-let or portfolio facility, frees a useful lump of cash while keeping a stake in the scheme's future value. Selling a portion also reduces the debt the retained units must carry, which can lift them clear of the interest cover ceiling that would otherwise cap a full refinance.
How does an exit bridge give me time to decide between selling and refinancing?
A development exit bridge clears the maturing development loan at or close to practical completion; it is set against gross development value, indicatively capped near 70 to 75 percent, and it costs less than the development finance it replaces now that build risk has fallen away. It opens a sales window of usually twelve to eighteen months with no decision forced by a hard maturity date, so you can test real sale prices and let a few units to establish rents before committing. Redemption comes either from sales, if you sell, or from a buy-to-let or term refinance, if you hold.
