If you've reached the point where you are looking to purchase a home, you are no doubt asking yourself: How long does a mortgage application take through a broker?
The short answer is usually between two and six weeks. At first, the mortgage application process can feel complicated. And there are lots of new, strange words and terms to try to understand.
There are several stages to the process, with varying time frames for each stage.
So, let's look at the different stages, how it works, how to avoid delays and then speed up the process where possible.
Summary
Almost everyone purchasing a property will need a mortgage. Mortgages are loans that lenders provide for people to buy a home, land or rental property.
Mortgage lenders are typically banks or building societies. After securing the mortgage deal, the borrower gradually repays the loan according to the terms agreed in the mortgage contract.
There are different types of mortgages with various terms and interest rates to consider. It can all seem highly confusing and overwhelming at first.
And unless you have the time and are willing to do extensive research, you could risk making a costly mistake.
Here is where mortgage brokers with all their knowledge, expertise and experience can assist most. They will guide you through the whole application process. They'll explain everything so that you understand what's happening throughout.
Using an experienced mortgage broker can help streamline the mortgage application process. The mortgage broker acts as a middleman between you and prospective lenders. And they have access to a multitude of different deals.
As part of their service, they compare deals from multiple lenders on your behalf. And, with their experience, they know what lenders need and expect. They are there to liaise with lenders for you when needed.
They will help you complete your mortgage application and submit documents correctly. Thus, helping to avoid potential delays.
The whole point of using a mortgage broker is to ensure things go as smoothly and hassle-free as possible. They aim to make the entire process easier and faster than going directly to banks and building societies yourself.
The first step is to find a reputable and established mortgage broker. Asking friends, family and work colleagues if they can recommend a broker, is a good starting point.
Do your own research on mortgage broker websites. Also, read reviews before making a list of companies to approach.
Like with most things in life, it's wise to shop around. Have an initial free consultation with several brokers before deciding who you feel most comfortable with.
Make an appointment with your selected broker to discuss your personal needs. Initial contact and appointments are easy to request online with minimal personal details.
During your first consultation, the mortgage advisor will need to get more detailed information from you. They need to understand your situation and what you are looking to achieve.
Get your documents ready for the advisor, you should collate your documents from the start to avoid delays. Below is a list of things you're going to need to submit to your mortgage broker and lender.
The more organised you are, the faster your broker can submit your application.
The best things here are a valid UK passport or driving license. However, if you don't have either, sometimes a birth certificate is acceptable.
Lenders will ask for two recent documents. Such as, utility bills, a council tax bill, a credit card statement or a bank statement. Or, if not used for ID, a UK driving license.
If you're employed, you need your last 3 months' payslips and your most recent P60. Also bank statements showing salary payments into your account.
If you're self-employed, you need 2-3 years of SA302 forms from HMRC. Or your accountant's reference and business accounts for the same period.
These should be from the last 3-6 months for all your accounts. And they need to show in comings, outgoings, along with existing credit card and loan payments.
This is usually your bank statements that show your savings. If the deposit is from a property sale, then you'll need evidence of the sale proceeds.
Suppose your deposit is a gift from family. You'll need a signed gift deposit letter confirming that the funds are not a loan.
You'll need to supply credit card statements and details of loans, car and other finance agreements you have.
Finally, once you've found a property you like and have made an offer that's accepted. You need to provide the estate agent's details and a memorandum of sale.

An application made before a stamp duty deadline can sometimes add weeks to the process.
Complicated applications for those with irregular income, self-employment and poor credit history can take longer. Often requiring additional checks and extra paperwork.
Traditional lenders are hesitant to approve loans to people with poor credit history. This is mainly because they lack confidence in the applicant’s loan repayment ability.
Issues with certain properties can also present problems. For instance, unusual or non-standard construction types or low valuations.
Failure to prepare the correct documents will cause delays. Every request for missing or replacement documents takes up more time. This scenario should be easy to avoid with the assistance of a mortgage broker.
