About MRT1 Mock Paper 3
Paper 3 is the most conveyancing-weighted mock in the unit: 13 of its questions sit in house-buying practice, ahead of 11 on affordability and 10 on mortgage law. It also carries six calculations, the joint-highest in MRT1. The effect is a paper that walks a transaction end to end — offer, searches, exchange, completion, registration — and stops at each stage to ask either a legal question or an arithmetic one. Candidates who have worked on a conveyance tend to find this the easiest of the standard-tier papers; those who have only studied it find it the hardest.
It is paper 3 of 5 in the MRT1 ramp, the Mortgage Law, Practice & Application unit, sitting in the standard tier. Every question carries a written explanation.

MRT1 Mock Paper 3 follows the live MRT1 format: 50 standalone questions, in 60 minutes — about 72 seconds a question. Pass mark 35/50 (70%), as in the real assessment. There is no negative marking, so answer everything.

Where candidates lose marks on MRT1 Mock Paper 3
Three traps this paper sets deliberately. Each one is a question where the wrong answer is the one most candidates would give.
The lender does not own the house
Under a charge by way of legal mortgage the borrower keeps the legal estate. The lender takes a proprietary security interest carrying statutory and contractual remedies, including possession and sale on default. The idea that legal ownership passes to the lender and reverts on the final payment is a popular myth and a standing exam distractor.
Absolute title is the strongest class, not a guarantee of a clean title
Registration with absolute title is the best class available for both freehold and leasehold, but the owner still takes subject to registered entries such as charges and covenants, and to overriding interests. The provisional-sounding alternatives — possessory and qualified — are weaker classes, so the question rewards knowing the hierarchy rather than the word.
Variable income gets shaded, not annualised
Basic salary is usually taken in full, but overtime and bonus are typically shaded — commonly to 50% — or averaged across payslips and P60s to test whether the income is sustainable. Annualising one exceptional month would overstate income, and is exactly the sort of manipulation the affordability rules exist to prevent.
First-time buyer relief does not stop at nil
Relief charges 0% up to £300,000 and then 5% on the portion from £300,001 to £500,000. A qualifying buyer at £340,000 therefore pays 5% on £40,000 — £2,000 — not nothing. Answering nil is only right at £300,000 or below, and the question is built to catch anyone who remembers the headline and not the band above it.
The 2% band applies to a slice, not to everything below it
On a £280,000 purchase the SDLT is £2,500 on the £125,000 in the 2% band plus £1,500 on the £30,000 above £250,000 — £4,000. The £5,600 option comes from applying 2% to the whole £280,000, which is the single most common structural error in stamp duty questions across the whole unit.
A worked example from MRT1 Mock Paper 3
A buyer has £30,000 saved. She sets aside £5,000 for fees, SDLT and moving costs and puts the rest towards a £250,000 purchase. What LTV does she need?
- 1.Ring-fence the transaction costs first: £30,000 − £5,000 = £25,000 genuinely available as deposit.
- 2.Express that as a share of the price: £25,000 ÷ £250,000 = 10%.
- 3.The loan is therefore the other 90%: £250,000 − £25,000 = £225,000.
Answer: 90% LTV
Treating the full £30,000 as deposit gives 12%, an 88% LTV, and a product the buyer cannot actually have. Forgetting to ring-fence costs is not just an exam error — it is the real-world reason cases fall over at the last minute, which is why the paper asks it this way round.
Try two questions from MRT1 Mock Paper 3
These come from the free preview of this paper. Answer them, then reveal the explanation.
Applications & affordability
A lender advances £337,500 against a property valued at £450,000. What is the LTV?
- A70%
- B66%
- C75%
- D80%
Reveal the answer
C is correct. LTV = £337,500 ÷ £450,000 × 100 = 75%. Working the other way, the deposit is £112,500, which is 25% of the value — the two figures must always sum to 100%.
Mortgage law
When a borrower grants a modern legal charge over her home, which statement correctly describes the parties' positions?
- ALegal ownership passes to the lender for the mortgage term, because the deed conveys the legal estate as security, and reverts to the borrower only on the final payment
- BThe lender becomes a joint registered proprietor with the borrower
- CThe borrower remains the legal owner, while the lender takes a charge giving it rights over the property — including possession and sale — if the debt is not repaid
- DThe borrower holds the property on trust for the lender
Reveal the answer
C is correct. Under a charge by way of legal mortgage the borrower (mortgagor) keeps the legal estate; the lender (mortgagee) takes a proprietary security interest carrying statutory and contractual remedies. The idea that the lender 'owns the house until you pay it off' is a popular myth — and a classic exam distractor.
Scored under 70%? Revise these next
A near miss is almost always a calculation you cannot do under time pressure, a definition you half-know, or a rule you have never read in the examiner's words. Start with the topic areas above where you dropped marks, then:
- →Drill the calculations on the CeMAP formula sheet — LTV, income multiples, SDLT, APRC, ERCs and rental cover, each worked through.
- →Nail the terminology in the CeMAP glossary — a surprising share of wrong answers are a term you nearly knew.
- →Re-read the syllabus coverage on the MRT1 exam guide, then sit the next paper in the ramp.
