Some specialist lenders (adverse credit, complex income) can take 2–3 working days." } }, { "@type": "Question", "name": "Does getting a mortgage in principle affect my credit score?", "acceptedAnswer": { "@type": "Answer", "text": "It depends. Some lenders (Nationwide, Halifax, most Building Societies) use a soft credit search that leaves no visible footprint.

Almost every UK estate agent will refuse to submit an offer to a seller until you can show a valid MIP. Sellers of desirable properties often ignore offers from buyers without one. Get your MIP before you start viewings, not after." } }, { "@type": "Question", "name": "Can a first-time buyer be refused a mortgage after getting an MIP?", "acceptedAnswer": { "@type": "Answer", "text": "Yes. An MIP is not a full underwriting decision. Between MIP and formal offer, the lender verifies your income, checks bank statements, valuates the property, and re-runs credit. Roughly 5%–10% of MIPs don't convert into full offers, usually because of undeclared debt, self-employed income variance or property valuation issues." } } ] } ] --- [Skip to content](#main) [London 020 8088 2997 ](tel:02080882997)[National 0333 567 1185 ](tel:03335671185) [![First Rung Now](/assets/logo-mark-CNo3p3DP.png) First Rung Now UK Mortgage Guides ](/) - Mortgages - Remortgages - Buy To Let - Bad Credit - Calculators - Guides - [Find a Broker](/find-a-mortgage-broker) - [About](/about) [London 020 8088 2997 ](tel:02080882997)[National 0333 567 1185 ](tel:03335671185) [Speak to a Vetted Broker](/find-a-mortgage-broker) 1.

FTB Mortgage in Principle UK Mortgage Guide # First-Time Buyer Mortgage in Principle: The 2026 UK Guide A Mortgage in Principle (MIP) is the first meaningful step in your journey as a first-time buyer. It converts a vague sense of what you might be able to borrow into a written figure that unlocks estate agent doors. But not all MIPs are equal — the wrong type, from the wrong lender, at the wrong time can knock 30 points off your credit score, or lock you to a lender that won't ultimately approve you. This guide explains exactly how to get an MIP as an FTB, which lender to start with, and how to convert your MIP into a full mortgage offer without hitting the common traps.

Free FCA-regulated introduction. We carefully check the broker matches your scenario — no pressure, no upfront fees. [Match me with a broker](/find-a-mortgage-broker) An MIP is a lender's written indication of how much they would in principle lend to you, based on the basic income and credit check they run at that point. It confirms three things: you exist, you have the income the lender needs to see, and your credit file passes their initial scorecard. It does NOT confirm the specific rate, the specific property, or that a full underwriter would ultimately approve you. ## Why FTBs need one before anything else Related · keep reading - [Bad credit mortgage checker Place your situation on the lender severity scale and see what a specialist will accept. ](/bad-credit-mortgage-checker) - [Bad credit second mortgage Secured second charges as an alternative to remortgaging when credit has slipped. ](/bad-credit-second-mortgage) Browse the full hub: [All mortgage guides](/mortgage-guides) Want a vetted broker to help with Why FTBs need one before anything else?

[Match me with a broker](/find-a-mortgage-broker) A soft credit search is only visible to you; other lenders can't see it. A hard search stays on your file for 12 months and is visible to every lender who runs a credit check. Multiple hard searches in 90 days signal financial distress and materially reduce your chance of a full offer. ### Lenders that use soft searches at MIP stage (safe to try) - Nationwide, Halifax, Skipton, Yorkshire BS, Coventry BS, Nottingham BS, TSB (varies) ### Lenders that use hard searches at MIP stage (only run once you're ready) - Barclays, HSBC, NatWest, Santander (typically), Metro Bank **The right sequence for an FTB:** run 2–3 soft-search MIPs first to test scorecards, then only run a hard-search MIP with the lender you actually intend to apply to.

Be honest on the application Every figure — income, outgoings, existing credit — gets verified in full underwriting. Inflating income by £3,000 to hit a target loan is the fastest way to fail underwriting and lose the property. ### 2\. Freeze new credit between MIP and offer Don't apply for new credit cards, car finance, BNPL agreements or overdraft increases. Even soft searches for insurance quotes can affect a marginal scorecard. ### 3\. Keep bank statements clean for 3 months Lenders review the last 3 months of bank statements. Avoid: gambling transactions, undeclared regular payments (child maintenance, private loans), sustained daily overdraft use. ### 4\. Match income evidence to the MIP figures If you declared £3,500/month gross, your payslips must show £3,500/month gross. Any discrepancy triggers manual underwriting and often reduced loan amounts. ### 5\. Get the property valued conservatively If a lender's surveyor down-values the property below your agreed price, they'll only lend on the lower figure. Ask your broker or estate agent for recent sold-prices in the street before you offer. ## What to do if your first MIP gets declined Related · keep reading - [Poor credit mortgage lenders The specialist UK lenders most willing to price recent adverse credit. ](/poor-credit-mortgage-lenders) - [MIP with bad credit Getting a credible MIP when your file shows defaults, CCJs or missed payments. ](/mortgage-in-principle-bad-credit) Browse the full hub: [All mortgage guides](/mortgage-guides) Want a vetted broker to help with What to do if your first MIP gets declined?
