Buy-to-Let Mortgages and Loans
A Simple Guide for First-Time Investors
Are you thinking about investing in a rental property? Whether you want to become a landlord for extra income or to build a property portfolio, buy-to-let mortgages and second charge loans can help you get started.
In this guide, we’ll explain what a buy-to-let mortgage is, how it works, and how second charge bridging loans can help you grow your property investments. It’s designed for people who are new to property investing, with no complicated jargon — just clear, useful information.
What Is a Buy-to-Let Mortgage?
A buy-to-let mortgage is a type of loan designed for people who want to buy a property to rent it out to tenants. It’s different from a standard residential mortgage, which is used to buy a home you plan to live in. Buy-to-let mortgages are usually interest-only, which means you only pay the interest each month. The original loan amount (the capital) is repaid at the end of the mortgage term — often by selling the property or using other funds.


How Does a Buy-to-Let Mortgage Work?
1Here’s a simple breakdown of how it works:
- Deposit: You’ll need a deposit, usually around 20% to 25% of the property value.
- Rental Income: Lenders want to see that the expected rent will more than cover your mortgage payments and other costs.
- Credit Checks: You’ll need a good credit score and steady income, even if you’re not living in the property yourself.
- Mortgage Term: You choose how long the mortgage runs — often between 5 to 25 years.
This type of loan helps you become a landlord, renting out your property to tenants and earning monthly rental income.
What Is a Second Charge Bridging Loan?
If you already own a property — either your home or a buy-to-let — and need more funds, a second charge bridging loan could be an option.
A second charge loan lets you borrow money using the equity (the value you own) in a property you already have. It’s called a “second charge” because it’s in addition to your main mortgage. The loan is secured against your property, but it doesn’t replace your existing mortgage — it “sits behind” it.
Why Use a Second Charge Bridging Loan?
- Buy another property quickly
- Fund home or rental property improvements
- Cover short-term costs during a property purchase or sale
These loans are especially useful when you need fast access to funds and don’t want to refinance your main mortgage.


When Might You Use a Second Charge Loan?
Here are some common examples:
- You’re buying a second buy-to-let property but need extra funds for the deposit.
- You want to renovate an existing rental property to increase its value and rent.
- You’re waiting for a property sale to go through and need cash in the meantime.
These bridging loans can be arranged quickly and usually last from a few months to a couple of years.
Key Things to Consider
Here are some important points to keep in mind before applying for a buy-to-let mortgage or second charge bridging loan:
1. Costs
You’ll need to cover:
- Upfront fees (valuation, legal, broker)
- Interest payments (monthly for mortgages, rolled up for some bridging loans)
- Maintenance and repairs for your property
- Landlord insurance and tax on rental income
2. Risks
Property values can go down as well as up, and if you can’t cover your repayments, your property could be at risk.
3. Exit Strategy
For bridging loans, lenders will ask for your “exit strategy” — how you plan to repay the loan. This might be through selling a property, refinancing, or rental income.
4. Legal Obligations
As a landlord, you must follow legal rules, including safety checks, tenancy agreements, and deposit protection schemes.
