The cash gap: why funded property deals still need money

The five costs a purchase loan does not cover

A loan calculated against a property's purchase price does not cover transaction costs, which must be funded separately in cash. That distinction matters from the moment an offer is accepted. The mortgage may cover the price agreed with the seller, but it will not cover the costs of getting the property into ownership, and those costs arrive on a fixed timetable that does not wait for rent to start.

None of these is covered by a loan calculated against the purchase price. The first three alone commonly run to a significant sum on a modest purchase, and they are payable before the property produces any income. Stamp Duty Land Tax applies to property purchases in England and Northern Ireland, with a surcharge on additional residential properties. A Stamp Duty Land Tax return and payment are due within 14 days of completion in England and Northern Ireland. Scotland charges Land and Buildings Transaction Tax and Wales charges Land Transaction Tax instead of Stamp Duty Land Tax, so the label and the deadline can differ depending on where the property sits.

Legal fees and disbursements are payable on completion of a property purchase. Lenders commonly charge valuation and arrangement fees, payable at application or on completion depending on the lender. Holding costs on an investment property include mortgage interest, buildings insurance, council tax and utilities, and accrue for every month the property is held. Those holding costs continue whether or not the property is tenanted, and they continue during any refurbishment period when no rent is being received. An investor who has calculated the deposit and the mortgage but not these five items has calculated only part of the money required.

Why refinancing is not the same as profit

When a property is refinanced after improvement, the new loan is larger and the difference is released as cash. That cash is borrowed. It is secured on the property, it carries interest, and it has to be repaid. This is the second confusion, and it is easy to see why it arises. The money arrives in a bank account, it looks like a return, and it can be spent like one. But the source of the money is a lender, not a buyer, and the property remains pledged against it.

A comparison between selling a property and refinancing it should separate four things. The first is cash returned to the investor. The second is equity still held in the property. The third is debt now outstanding against it. The fourth is income that continues or stops. Selling converts equity into cash and ends the income. Refinancing returns cash, keeps the property, keeps the income, and creates or enlarges a debt. Those are different outcomes, and treating them as equivalent obscures what has actually happened.

Recovering the original cash contribution through a new mortgage does not mean the investor has both realised a profit and kept the property, because the money came from a lender rather than from a buyer. The property is now security for a larger loan. If values fall, the debt does not fall with them. If the property is sold later, the larger loan is repaid first, and the cash released earlier has already been accounted for in that repayment. Money released by refinancing a property is borrowed against that property, carries interest and must be repaid. That is the whole of the mechanism, and it is worth stating plainly because the cash arriving in the account can feel like a gain when it is an advance.

Why a profitable project can still run out of money

Development and refurbishment finance is commonly released in stages against work that has been completed and verified. Contractors generally expect payment on or shortly after completing a stage. That creates a timing gap in which work has been done, money is owed, and the lender has not yet released funds. The project may be entirely sound on its final figures. The budget may balance, the end value may exceed the total cost, and the plan may be correct in every respect. None of that prevents a cash shortfall in the middle of the works.

The size of the gap depends on the draw schedule, the speed of the monitoring surveyor and the payment terms agreed with the contractor. A draw schedule sets out how many releases there are and what triggers each one. A monitoring surveyor verifies that the work claimed has actually been done before funds are released. Contractor payment terms set out when an invoice must be settled. If the contractor expects payment within seven days of completing a stage, and the lender releases funds three weeks after verification, the investor funds the difference in the meantime. That difference is real money, and it is needed before the project completes.

An investor needs to know when money arrives, not only whether the budget balances overall. A project can be entirely sound on its final figures and still fail because of this. The failure is not usually a failure of the property or the plan. It is a failure of timing, and it can force a sale at the wrong moment, a costly short term loan, or a stalled site. The question is not whether the numbers work at the end. The question is whether the money is available at each point where it is needed, and those are different questions with different answers.

Questions worth answering before committing

How much cash is needed on completion day, separately from the loan. What is the total of fees and tax, and when is each payable. On a staged loan, how many draws are there, what triggers each one, and how long does verification take. What are the contractor payment terms, and do they align with the draw schedule. What are the monthly holding costs, and how many months of them can be funded if the work overruns. On exit, what would a sale return after costs and tax, and what would a refinance return, with borrowed money and retained equity shown separately.

These are questions rather than instructions, and the answers will differ by property, lender and location. Income tax is payable on rental profits from a property let in the UK. Capital Gains Tax may be payable on the disposal of a property that is not the owner's main residence. The Bank of England publishes the official Bank Rate, which influences mortgage interest rates. Most buy-to-let mortgages are not regulated by the Financial Conduct Authority, although some, such as consumer buy-to-let, are. Each of these affects the cash position, and each has a timing as well as an amount.

An investor who cannot answer these does not yet know whether the deal works. That is not a judgement about the deal. It is a statement about the state of the information. The figures may be excellent and the answers may be straightforward, but until they are written down and checked, the plan rests on assumptions. The three confusions set out above each cost money in a different way. The first costs money on completion day. The second costs money in misread returns. The third costs money in the middle of the works, when there is least room to absorb it.

Where this framing comes from

These three distinctions are set out at length in The Finanze Framework: Property Strategy and Finance Success by Alastair Hoyne, founder of Finanze Group, published on 30 October 2026, which works through them using transaction examples. Alastair Hoyne's background spans investment banking, global markets, investment management and entrepreneurship. Finanze Group comprises separate businesses covering specialist short-term property lending, brokerage and property strategy consulting.

Frequently asked questions

Does a mortgage cover Stamp Duty Land Tax?

No. A loan calculated against a property's purchase price does not cover transaction costs, which must be funded separately in cash. Stamp Duty Land Tax applies to property purchases in England and Northern Ireland, with a surcharge on additional residential properties, and a return and payment are due within 14 days of completion in England and Northern Ireland.

Is money released by refinancing profit?

No. Money released by refinancing a property is borrowed against that property, carries interest and must be repaid. Recovering the original cash contribution through a new mortgage does not mean the investor has both realised a profit and kept the property, because the money came from a lender rather than from a buyer.

Why can a project with a sound budget run out of cash?

Development and refurbishment finance is commonly released in stages against work that has been completed and verified. A timing gap can arise between a contractor completing and invoicing for a stage of work and a lender releasing the corresponding funds. The size of the gap depends on the draw schedule, the speed of the monitoring surveyor and the payment terms agreed with the contractor.

What should be separated when comparing selling and refinancing?

A comparison between selling a property and refinancing it should separate cash returned, equity retained, debt outstanding and continuing income. Selling converts equity into cash and ends the income. Refinancing returns cash, keeps the property, keeps the income, and creates or enlarges a debt.

Which holding costs apply while a property is held?

Holding costs on an investment property include mortgage interest, buildings insurance, council tax and utilities, and accrue for every month the property is held. They continue whether or not the property is tenanted, including during any refurbishment period when no rent is being received.
