What should a property deal pack contain?
A deal pack should contain, at minimum: the property's address with a link to the listing and its key facts; the price alongside the sold comparables evidence that justifies the value claimed; a refurbishment schedule with its scope, contingency and VAT position stated; the GDV with its basis shown, meaning which comparables of finished stock support it and how; rent evidence from matched lettings comparables; the strategy figures, such as flip profit, yield, monthly cash flow or cash left in after refinance, with the workings visible; the finance assumptions used, including rates, loan-to-value, term and fees; and a plain statement of the risks and what the deal looks like if key numbers come in worse.
What separates a pack an investor trusts from a sales brochure is not length or polish, it is evidence and honesty. Every material number should be traceable to a source, every assumption should be stated so the reader can change it and see what happens, the figures should reconcile with each other across the pack, and the risks should be volunteered rather than extracted. A pack built that way lets an experienced investor verify the deal in minutes, which is precisely the point of paying for one. This guide goes through each component in turn and finishes with what makes investors trust a pack, and what makes them bin it.
The property itself: identity and facts
Start with the basics done properly: the full address, a link to the live listing, the photographs, the property type and bedroom count, the floor area with its source stated (the EPC record is the usual one), and the tenure, including the lease length, ground rent and service charge where the property is leasehold, because those move value and mortgageability. Some sourcers withhold the address until a buyer commits or a fee agreement is signed, which is a legitimate commercial practice, but the pack the buyer ultimately relies on must identify the property precisely: nobody can verify comparables, planning or licensing against a mystery address.
Include the facts that gate the strategy, not just the ones that sell it. For an HMO deal that means the planning position, including whether the address sits in an Article 4 area, and the licensing requirements. For a flat it means the lease detail. For anything structural it means access, and any known issues visible from the listing or a viewing. A pack that is silent on the gating facts is not shorter, it is unfinished.
Price and the evidence for value
State the asking or agreed price, then evidence the value rather than asserting it. That means listing the sold comparables individually: address, sold price, sale date, distance, bedrooms, type, and the condition each sold in, ideally with a link to the original listing so the reader can check the photographs. A claimed market value with no visible comparables is an opinion, and a below-market-value claim built on an opinion is a discount from an imaginary number.
The comparables should be genuine ones: recent registered sold prices, matched on type and size, condition-sorted, drawn from the same micro-market. If the pack claims the property is being bought below market value, the evidence has to show what the market value is and where the figure comes from; if the discount only appears when the property is compared against renovated stock, that is a confusion of GDV with current value, and experienced buyers will spot it immediately.
Refurbishment schedule and GDV, each with its basis
The refurbishment section should show its scope room by room or element by element: what is being done, to what specification, at what estimated cost, with a contingency stated separately and the VAT position clear. A single unexplained figure for "refurb" is the weakest number in most packs, and the one most likely to sink the deal when reality arrives. Stating the assumed specification matters as much as the cost, because the GDV depends on delivering it.
The GDV then needs its own evidence, and it is different evidence from the current-value comparables: sold prices of similar properties in finished, done-up condition, the stock your property will compete with after the works. Show which comparables support the figure, what adjustments were made, and why the chosen number is defensible rather than the top of the range. A pack that presents one comparables list and uses it for both the current value and the GDV is mixing two different questions, and one of the two answers is wrong.
Rent evidence and the strategy figures
If the strategy involves letting, the rent needs the same treatment as the value: matched lettings comparables near the property, same bedroom count and type, with let-agreed evidence preferred to asking rents, and the figure taken from the middle of the range rather than the top. For HMO deals, room-level evidence and the achievable standard matter, alongside the planning and licensing position that determines whether the room income is lawful at all.
Then the strategy figures, with the workings shown. For a flip: profit after purchase costs, refurbishment, finance, selling costs and the margin that remains as a percentage of GDV. For a rental: yield, monthly cash flow after the mortgage and running costs including voids and maintenance. For a refinance-led deal: the assumed end value and loan-to-value, the cash returned, the cash left in and what remains as monthly income. Every one of these should be reproducible by a reader with a calculator using only the numbers in the pack; if it is not, the pack is asking to be trusted rather than checked.
Finance assumptions and risks, stated plainly
Finance assumptions belong in the open, because they move every downstream figure: the product assumed, the rate, the loan-to-value, the term, arrangement and broker fees, and for bridged deals the assumed months of holding and the exit. A pack whose numbers only work at an optimistic rate or an unrealistic loan-to-value should say so in its own tables, and a good pack makes that visible rather than burying it.
The risk section is where trust is won or lost. Every deal has risks: the survey may find more than the photographs showed, the refurbishment may overrun, the end valuation may come in under the GDV, rates may move before the refinance, planning may be refused, the rent may land at the bottom of the range. A pack should name the risks that apply and show the sensitivity: what the deal looks like if the GDV or the rent comes in lower, or the works cost more. Naming risks does not weaken a good deal; a deal that survives its own risk section is exactly what an experienced investor is looking for.
- State the assumed product, rate, loan-to-value, term and all fees.
- For bridging: months assumed, total finance cost and the exit route.
- Name the risks that apply to this deal specifically, not a generic list.
- Show sensitivity: the deal at a lower GDV, a lower rent and a higher cost.
- If the deal only works on the best case, the pack should make that visible, not hide it.
What makes investors trust a pack
Investors who see many packs converge on the same tells. Trustworthy packs are evidenced, consistent and falsifiable: the reader can check every claim, the numbers agree with each other wherever they appear, and the assumptions are laid out so the reader can disagree with one and re-run the deal. Untrustworthy packs assert instead of evidencing, quote round numbers with no source, show a comparables list that does not survive five minutes on the portals, and treat risk as a section to be omitted.
The author matters too. A pack from a sourcer should identify who compiled it, and a professional sourcer operating in the UK should be registered for anti-money-laundering supervision, a member of a redress scheme and properly insured, which a serious pack is not shy about saying. Consistency across deals is the final tell: a sourcer whose packs apply the same method and the same honesty to every deal, including the ones that do not stack, is showing you their process rather than their sales patter.
- Every material number traceable to a source the reader can check.
- Assumptions explicit and changeable, not baked invisibly into results.
- Figures that reconcile: the same rent, price and costs wherever they appear.
- Conservative selections from evidence ranges, not top-of-range anchoring.
- Risks and sensitivities volunteered, with the deal shown under worse cases.
- An identifiable, compliant author who applies the same method to every deal.
How to assemble a deal pack step by step
The order of work for compiling a UK property deal pack whose every number can be checked, from property facts through evidence to risks.
- 1
Gather the property facts
Record the full address, listing link, photographs, type, bedrooms, floor area with its source, and tenure including lease details where relevant. Add the gating facts for the intended strategy, such as the Article 4 and licensing position for an HMO.
- 2
Build the value evidence
List sold comparables individually with price, date, distance, size, type and condition at sale, and state the current value they support. Any below-market-value claim must be a discount from this evidenced figure, not from an asking price or a hope.
- 3
Price the works and evidence the GDV
Set out the refurbishment scope room by room with costs, a stated contingency and the VAT position. Evidence the GDV separately, from sold comparables in finished condition, and show the adjustments that lead to the chosen figure.
- 4
Evidence the rent and run the strategy figures
Support the rent with matched lettings comparables, preferring let-agreed evidence. Then compute the strategy figures, flip profit, yield and cash flow, or refinance outcome, showing workings a reader can reproduce with a calculator.
- 5
State finance, risks and run the consistency check
Declare every finance assumption, name the deal-specific risks and show sensitivity to a lower GDV, lower rent and higher costs. Finally, check the pack agrees with itself: the same numbers everywhere they appear, and totals that add up.

Frequently asked questions
What should a property deal pack include?
The property's identity and key facts including address, listing, floor area and tenure; the price with sold comparables evidence for the value claimed; a refurbishment schedule with scope, contingency and VAT stated; the GDV with the finished-stock comparables that support it; rent evidence from matched lettings comparables; the strategy figures with visible workings; the finance assumptions used; and a plain statement of risks with sensitivity to worse outcomes. Every material number should be traceable to a source the reader can check.
How many comparables should a deal pack show?
Enough genuine ones to support the figure, listed individually with price, date, distance, size, type and condition at sale. A handful of true matches, recent, close, condition-sorted and drawn from the same micro-market, is worth more than a long list of loose ones, and far more than an unevidenced assertion of market value. If evidence is thin, the pack should say so and carry a range rather than fake precision.
Should a deal pack include risks?
Yes, prominently. Every deal carries risks: survey surprises, refurbishment overruns, a lower end valuation, rate moves, planning refusals, rent at the bottom of the range. A pack that names its specific risks and shows the deal under worse cases is more credible, not less, because it demonstrates the deal survives scrutiny. Experienced investors treat a missing risk section as a warning about the whole pack.
What makes a deal pack look untrustworthy?
Asserted values with no visible comparables, below-market-value claims measured against asking prices or renovated stock, a single unexplained refurbishment figure, numbers that disagree with each other across pages, top-of-range figures presented as expectations, no finance assumptions, no risks, and an anonymous author. Each of these is fixable, and a pack that fixes none of them is telling you how the rest of the relationship will go.
What is the difference between the value evidence and the GDV evidence?
They answer different questions from different comparable pools. The current value is evidenced by sold properties in similar as-is condition to the one being bought; the GDV is evidenced by sold properties in finished, done-up condition, the stock the property will compete with after the works. A pack that uses one list for both has confused the two, and either the discount claimed or the end value claimed is inflated.
Do deal packs from sourcers need compliance details?
A professional UK sourcer should be registered for anti-money-laundering supervision, belong to a government-approved redress scheme, hold professional indemnity insurance and handle data lawfully, and a serious pack identifies its author and their compliance position. It is also a practical filter for buyers: a sourcer meeting their legal obligations is more likely to be applying the same care to the numbers.
