  • Know when to get a Mortgage in Principle and how a broker can keep things moving.

1. What does the first time buyer timeline really look like?

Every case is different, but most first time buyers in the UK follow a similar pattern.

From first organising your finances to picking up the keys, the full journey often takes around 3 to 6 months, sometimes longer.

A very rough guide looks like this:

  1. Get a soft search Mortgage in Principle (MIP / AIP)
    Often within minutes to 48 hours once you have given your details.
  2. View properties and make an offer
    Can be very quick if you find the right home in your first few viewings. It can take several weeks if you are still deciding on area or budget.
  3. Full mortgage application and underwriting
    Lenders often take around 2 to 4 weeks to assess and issue a full mortgage offer, depending on how busy they are and how complex your situation is.
  4. Conveyancing, searches and legal work
    From offer accepted to completion, most purchases take around 8 to 12 weeks.
  5. Exchange, completion and keys
    You will agree a completion date with the seller, often 1 to 4 weeks after exchange, if the chain is ready.

If you are hoping to start viewings before Christmas, the key job now is to be mortgage ready, with your paperwork and Mortgage in Principle lined up so you can move quickly when you see a property you like.

2. Before Christmas: 6 smart steps to get mortgage ready

Step 1 – Check and tidy your credit file

Money saving forums and other UK boards show the same worries again and again. People feel anxious about:

  • Old missed payments or defaults
  • Debt management plans or consolidation loans
  • Payday loans or heavy use of overdrafts
  • What underwriters will think about their everyday spending

The good news is that many people have the odd blip on their credit report. It does not always mean you cannot get a mortgage, but it is important to understand your position.

You can see your full UK credit file and reports from multiple agencies in one place here: Check My File. 
Please note: Check My File offers a FREE 7 Day trial that will enable you to download your current credit report. Please remember to cancel the subscription within 7 days, if you do not wish to continue with this service.

When you review your credit file:

  • Check for errors and ask the agency to correct anything that is wrong.
  • Make sure all active accounts are on the correct address.
  • Try to avoid using your overdraft regularly in the run up to your application.
  • If you can, bring any missed payments up to date and keep everything paid on time now.

If you already know you have missed payments, defaults or a debt management plan, a specialist broker can often place cases with specialist lenders who are more comfortable with this type of risk.

Step 2 – Work out your budget and deposit

Lenders look at three main areas:

  • Your income
  • Your fixed commitments such as loans, cards, childcare and car finance
  • Your deposit and the property price

In the current UK market, many lenders will consider a 95% loan to value mortgage, which means a 5% deposit, although criteria can be tighter at this level.

You might:

  • Aim for a 5% deposit to get on the ladder sooner.
  • Aim for 10% or more if you want a wider choice of deals and potentially sharper interest rates.

Also think about fees and moving costs, not just the deposit:

  • Solicitor and conveyancing fees
  • Survey and valuation costs
  • Searches and Land Registry fees
  • Possible Stamp Duty, depending on where you buy and property price
  • Moving costs and any immediate repairs or furniture

This is where a simple budget planner or mortgage calculator can help you see what is realistic for you.

Step 3 – Get your documents Christmas ready

Money saving and Reddit style forums show plenty of worry about what lenders will see on bank statements. Common questions are:

  • Will they judge the odd takeaway or night out?
  • Will subscriptions cause a problem?
  • How many months do they check?

In practice, lenders are usually looking for patterns and commitments, not the odd coffee.

Typical documents a first time buyer will need include:

  • Photo ID such as a passport or driving licence
  • Proof of address
  • Last 3 months bank statements
  • Last 3 months payslips and recent P60 if you are employed
  • SA302s and tax year overviews if you are self employed
  • Details of any loans, credit cards, car finance or childcare costs

If you can, aim to:

  • Avoid unarranged overdrafts
  • Avoid gambling transactions and very large, unexplained movements
  • Keep your income going to one main account that you can show clearly

Having these documents ready before Christmas means your broker can move quickly once you have found a property.

Step 4 – Think about gifted deposits and family help

A lot of forum questions focus on parents helping with deposits and whether this causes tax or benefit issues.

From a lender’s point of view:

  • Most mainstream lenders are comfortable with gifted deposits from close family, as long as it is a genuine gift and not a loan.
  • The person gifting the money will normally have to sign a declaration to confirm they do not expect repayment and will not have a legal interest in the property.

If you are planning to receive help from family:

  • Talk about it early so everyone understands what is being offered.
  • Keep a clear paper trail of the funds.
  • Mention it to your broker at the start so they can choose lenders that are happy with your plans.

There are also a few newer products in the market aimed at buyers with very small deposits, sometimes as low as 2 to 5%, but these are quite specialist and can carry extra risk. An adviser will be able to explain whether these may be suitable for you.

Step 5 – Understand your Agreement in Principle (AIP / MIP)

What it is

A Mortgage in Principle, also called an AIP, DIP or MIP, is the lender’s early view of how much you may be able to borrow based on a snapshot of your information. It is not a full mortgage offer and it is not a guarantee.

For most first time buyers:

  • A soft search MIP or DIP will not impact your credit score.
  • Many lenders and brokers can produce one within minutes once they have your basic details.

Why you should get one before Christmas

If you want to start serious viewings in December:

  • An AIP shows estate agents that you are a serious buyer.
  • It helps you focus on properties in your true price range.
  • It gives you time to fix any issues that show up before you make an offer.

Step 6 – Use a broker to navigate lender rules and timescales

Online and forum discussions often highlight:

  • Confusing and sometimes conflicting advice from banks and estate agent advisers
  • Worries about being declined after valuation
  • Delays with solicitors and searches

A dedicated broker can:

  • Look across around 130+ UK lenders and thousands of products, including broker only ranges, rather than being tied to one bank.
  • Match your situation, for example overtime, bonuses, self employment, debt management plans and old defaults, to lenders that are more likely to consider you.
  • Help you understand the timeline and chase the process with the lender and solicitor.

3. From Christmas viewings to keys: step by step

Once Christmas viewing season starts and you have an AIP in hand, your journey looks roughly like this.

Step 1 – Viewings and offers

  • Shortlist areas and property types that fit your budget.
  • View a few homes to get a feel for sizes and layouts.
  • When you are ready, make an offer through the estate agent, backed up with your AIP.

Step 2 – Offer accepted and full application

Once the seller accepts your offer:

  1. Your broker will complete a full mortgage application with your chosen lender.
  2. You will provide all supporting documents.
  3. The lender will run full affordability checks and instruct a valuation.

Many lenders aim to issue a full mortgage offer in around 2 to 4 weeks, although more complex cases can take longer.

Step 3 – Valuation and survey

The lender’s valuation confirms that the property is suitable security for the mortgage.

You may also choose a more detailed survey in case of:

  • Older properties
  • Renovation projects
  • Flats with complex leases
  • Anything that worries you from the viewing

Forums show many first time buyers are unsure what to do if a survey picks up issues:

  • Minor issues often just become part of your maintenance plan.
  • More serious issues may lead to renegotiation on price or asking the seller to fix things.
  • In some cases, you may decide to walk away.

Your broker and solicitor will help you understand your options.

Step 4 – Conveyancing, searches and legal checks

Your solicitor or conveyancer will:

  • Check the legal title to the property
  • Order local authority, water and environmental searches
  • Review the contract and any leasehold information
  • Deal with your lender’s legal requirements

Most transactions take around 8 to 12 weeks from offer accepted to completion, although chains, slow searches and legal complications can extend this.

Step 5 – Exchange, completion and moving day

When everyone in the chain is ready:

  1. You exchange contracts and pay your deposit to the solicitor.
  2. The date for completion is set.
  3. On completion day, your lender releases the funds and you collect your keys.

You may be able to agree a completion date that works for you and the seller, for example early in the new year if you are viewing around Christmas.
