Are you tired of struggling to save up for a deposit on your dream home? A 100% mortgage could be the solution. But before you dive in, it's important to know what you're getting into. Read on for a comprehensive guide on everything you need to know about 100% mortgages in the UK.

What is a 100% Mortgage?

So, you're thinking of getting a 100% mortgage? Let's break it down for you. A 100% mortgage is a loan that covers the entire cost of your property, allowing you to secure a mortgage without having to put down a deposit. Sounds too good to be true, right? Well, let's look at the requirements first. To qualify for a 100% mortgage, you will need to have a good credit score, a stable employment status, and most importantly, a high level of affordability. This means that you need to have a robust financial standing in the eyes of the lender. Now, let's weigh the pros and cons. On the one hand, a 100% mortgage allows you to get onto the property ladder without having to save for years to provide a deposit. However, on the other hand, it can be more costly in the long run. These types of mortgages often come with higher interest rates, which means you'll end up paying more in the long run. Nevertheless, a 100% mortgage can be a suitable option if you meet the requirements and it's the only way for you to secure a property. Just make sure you get the appropriate advice to guide you through the process.

Types of 100% Mortgages

Types of 100% Mortgages: There are various types of 100% mortgages available in the UK market. Each type has its own unique features and eligibility criteria. Let’s take a look at them one by one:

Family Deposit Mortgages: This type of mortgage allows a family member to deposit a percentage of the property price as security for the loan. This enables the borrower to get a mortgage without having to save for a deposit.

Guarantor Mortgages: A guarantor mortgage allows a family member or friend to guarantee the loan repayments if the borrower defaults. This type of mortgage often allows a borrower to borrow more than they would be able to on their own.

Joint Borrower-Sole Proprietor Mortgages: This type of mortgage allows multiple borrowers to apply for a mortgage together, while only one borrower is named as the legal owner of the property. This can be useful for those with low income and bad credit scores.

Self-Build Mortgages: A self-build mortgage provides funding for the construction of a property. It is a good option for those who want to build their own home from scratch. Whichever type of 100% mortgage you opt for, make sure you understand the terms and conditions carefully, and that you seek professional advice from a mortgage broker.

Qualifying for a 100% Mortgage

Qualifying for a 100% Mortgage can be challenging, but it is possible with the right preparation. Lenders are strict when it comes to credit scores, income stability, and affordability. A poor credit score can significantly affect your chances of approval, but there are still lenders willing to lend to those with a lower score. It's essential to have a stable employment status, which means being employed full-time and in a permanent role. Employment history is also crucial, as frequent job changes could be a red flag to lenders. You also need to prove that you can afford the mortgage, typically by showing payslips, bank statements, and utility bills. Having a deposit, although not necessary for 100% mortgages, can also be helpful in improving your chances of getting approval. This shows lenders that you are financially responsible and can save for a deposit. Interest rates on 100% mortgages can be higher than standard mortgages, and it's crucial to understand the terms and conditions. Seeking professional advice is vital to ensure you are getting the best deal while avoiding any pitfalls. Let's find the right mortgage for you!

Pros and Cons of a 100% Mortgage

100% mortgages may seem like a dream come true for many first-time buyers struggling to save. A significant advantage is not requiring a deposit, but it also has its drawbacks. If you have a stable income, a reliable credit score, and affordability is not an issue, then such mortgages might work for you. But remember, a 100% mortgage often has higher interest rates compared to those with a deposit. Besides, if the value of your property falls, you could end up owing more than your property’s worth. It’s essential to weigh the pros and cons before deciding.

Importance of Seeking Professional Advice

When it comes to making such a significant financial decision, professional advice is crucial. An expert can provide guidance on the best course of action and help you navigate complex mortgage applications. Don't hesitate to seek assistance from a financial advisor or mortgage broker.


In summary, 100% mortgages are a great option for those who meet the strict criteria. However, it's important to consider the pros and cons and seek professional advice before making a decision. These mortgages are not for everyone, so weigh your options carefully.
