What does a lender’s mandate actually tell you?
A lender’s mandate is not just a marketing sheet. It is the blueprint for what you need to put in the pack. Every parameter in the mandate — LTV, term, deal size, asset type, geography, borrower profile — maps directly to a documentation requirement. If you can read the mandate properly, you can reverse-engineer exactly what your pack needs to contain before you collect a single document.
Most brokers scan a mandate for the headline numbers: maximum LTV, rate range, minimum loan size. They check whether the deal fits, and if it does, they submit. That is how you get follow-up questions. The broker matched the deal to the lender on three parameters and missed the ten other requirements buried in the mandate’s detail.
The discipline of reading a mandate properly — and structuring your pack around what it tells you — is what separates brokers who submit once from brokers who submit and wait for questions.
What are the key parameters in a lender mandate?
Every lender mandate contains a core set of parameters. Understanding what each one implies for your pack is the skill.
Loan-to-value (LTV). The headline number, but it carries documentation requirements. If the mandate says maximum 70% LTV, your pack must include a valuation that supports the LTV calculation exactly. The lender will check the maths — purchase price or current value, loan amount, and the resulting percentage. If you are relying on a higher valuation to hit the LTV threshold, the valuation methodology and comparable evidence need to be strong enough to withstand scrutiny.
Loan size range. Minimum and maximum loan amounts signal the lender’s target market. A lender with a minimum of two million pounds is not set up to process a five hundred thousand pound deal efficiently, even if they technically could. The loan size also affects documentation depth — larger deals typically require more detailed sponsor information, more comprehensive financial modelling, and stronger exit evidence.
Term and product type. A 12-month bridging mandate has different documentation requirements from a 5-year commercial mortgage mandate. The term tells you what the lender cares about most. Short-term lenders focus on exit certainty — they want to see how they get repaid. Long-term lenders focus on income sustainability — they want to see how the borrower services the debt over the full term.
Asset type and use class. A mandate that specifies “residential investment” excludes HMOs unless stated otherwise. A mandate covering “light industrial” will not extend to heavy manufacturing sites. The asset type determines the property documentation required — a commercial unit needs lease documentation, tenant covenant evidence, and potentially environmental reports that a standard residential asset does not.
Geography. Some lenders are national. Others concentrate on specific regions or exclude certain postcodes. If the mandate specifies geography, do not assume your deal is an exception. If the property is on the boundary of the lender’s geographic appetite, address it explicitly in the deal summary rather than hoping they will not notice.
Borrower profile. Many mandates specify minimum experience, net worth thresholds, or borrower type requirements (e.g., SPV only, UK-resident directors, no first-time developers for development finance). These translate directly into sponsor documentation — CVs, track records, personal asset statements, and company structures that evidence compliance with the borrower criteria.
How do I reverse-engineer the pack structure from the mandate?
This is the practical skill. Take each mandate parameter and convert it into a document requirement.
Step 1: List every parameter in the mandate. Go through the entire mandate document — not just the summary table. Read the footnotes, the exclusions, the “additional requirements” section. List every criterion the lender has stated.
Step 2: Map each parameter to a document. LTV requirement maps to valuation plus loan schedule. Asset type maps to property documentation appropriate to that class. Borrower profile maps to sponsor pack contents. Exit strategy requirement maps to the evidence you need to include (sale comparables, refinance DIP, planning consent for a development exit). Build a document list that is specific to this lender and this deal.
Step 3: Identify where your deal sits on the edge of criteria. If the mandate says maximum 75% LTV and your deal is at 73%, that is fine but the valuation needs to be bulletproof. If the mandate says “experienced developers” and your borrower has two completed projects, you need to present those two projects in maximum detail. Edge cases are where lenders ask the most questions. Anticipate them.
Step 4: Build the deal summary around the mandate’s priorities. The deal summary should mirror the mandate’s structure. If the lender leads with asset type, lead with the property. If they lead with borrower profile, lead with the sponsor. If exit strategy is prominently featured, make your exit evidence the strongest section of the summary. The credit analyst reading your pack should see their own criteria reflected back in your structure.
Step 5: Address exclusions and edge cases explicitly. If the mandate excludes certain property types and your deal is close to but not within an exclusion, say so in the deal summary. “The property is classified as Use Class E(g)(i) — office use — and does not fall within the excluded light industrial category.” Leaving ambiguity for the lender to resolve is how you trigger a round of questions.
Why does this discipline matter more than finding the cheapest rate?
Because the cheapest rate means nothing if the deal does not complete. A broker who finds a lender offering 50 basis points less but submits a pack that does not match the mandate will lose weeks to questions, conditions, and potential decline. A broker who submits a pack that is structured precisely around the lender’s mandate — even at a slightly higher rate — closes the deal.
Borrowers judge you on completion, not on the indicative terms you presented at instruction. The broker who completes at 7.5% delivers more value than the broker who quotes 7% and then spends six weeks chasing lender questions.
How do I handle mandates that are vague or incomplete?
Some lenders publish detailed mandates with clear parameters. Others publish a one-page summary that tells you very little. When the mandate is vague, you have two options.
Call the BDM. Before submitting, speak to the lender’s BDM and walk through the deal. Ask specifically: what documentation do you need pre-submission? Are there any criteria not in the published mandate? What kills deals for you at credit committee? A ten-minute call can save you a week of back-and-forth.
Use your lender intelligence. If you have submitted to this lender before, use the patterns from previous deals. What did they ask for last time? What conditions did they impose? What documentation gaps did they flag? This operational knowledge — built deal by deal — is more valuable than the published mandate for predicting what the lender actually needs.
The best brokers do both. They read the mandate, call the BDM, reference their own deal history with that lender, and then build the pack. By the time they submit, the pack answers every question the credit committee is likely to ask. That is not luck. It is process.
What happens when you consistently match packs to mandates?
The same thing that happens when you consistently submit clean packs: lenders start to trust you. When a lender’s BDM knows that your submissions are structured around their criteria, your deals move faster through credit. You get terms back sooner. You get fewer conditions. And when capacity is tight, your deals get prioritised over the broker who submits and hopes.
This is the compounding advantage of operational discipline. Each deal builds the relationship. Each clean submission reinforces the lender’s confidence. Over time, you are not just submitting deals — you are building a reputation that makes every subsequent deal easier to place.
