How Does a Buy-to-Let Mortgage Work?
Buy-to-let (BTL) mortgages are essential if you’re planning to purchase a property to rent out. Whether you’re a first-time landlord or building a portfolio, understanding how a buy-to-let mortgage works is crucial to making the right investment decisions.
At Novellus Property Management, we help landlords across Manchester maximise returns on their buy-to-let properties through our tailored lettings and management services. Here’s everything you need to know.
What Is a Buy-to-Let Mortgage?
A buy-to-let mortgage is a loan specifically designed for purchasing property intended for rental rather than owner-occupation. Unlike residential mortgages, BTL loans assess affordability based on projected rental income rather than your salary alone.
Lenders typically require:
- A larger deposit (usually 25%)
- Higher interest rates
- Proof that rental income will cover 125–145% of the mortgage payments
Key Differences from a Residential Mortgage
There are several differences between a buy-to-let and residential mortgage:
| Feature | Residential Mortgage | Buy-to-Let Mortgage |
|---|---|---|
| Purpose | Owner-occupied home | Rental property |
| Affordability | Based on income | Based on rental yield |
| Deposit | From 5% | From 20–25% |
| Interest Type | Often repayment | Often interest-only |
| Fees | Standard | Higher arrangement fees |
For landlords interested in a hands-off approach, our fully managed lettings service takes care of everything from tenant sourcing to rent collection and compliance.
How Does an Interest-Only Buy-to-Let Mortgage Work?
Most BTL mortgages are interest-only. This means you only pay the interest each month, and repay the full capital at the end of the mortgage term. This keeps your monthly payments lower, allowing you to benefit from rental income as cash flow.
However, you’ll need a repayment strategy – either by selling the property, refinancing, or using savings or investments.
What Do Lenders Look For?
To be eligible for a buy-to-let mortgage, lenders usually look at:
- Rental income projections
- Your credit history
- Your experience as a landlord (some lenders favour experienced landlords)
- Whether you already own a property
They may also require that the property meets certain rental yield thresholds. Working with an experienced letting agent like Novellus can help ensure your property is priced and marketed to achieve strong rental yields.
Buy-to-Let Mortgage Eligibility
You don’t have to be a high earner to qualify, but many lenders require:
- A minimum annual income (e.g., £25,000+)
- A solid credit score
- A sizeable deposit
- Ownership of another property
