01
Working out the rental cover first
Before you offer. Take the expected rent, compare it with the lender’s stress test, and you will know the maximum loan before you commit to anything.
Buy-to-let
“I am buying my first rental property and do not know where to start”
A first buy-to-let mortgage is assessed mainly on the rent the property will produce rather than on your income, stress-tested against the payment with a margin. Most lenders expect a deposit of at least 25%, and many prefer that you already own your own home.

Sound familiar?
- This is your first investment property
- You have a deposit but are unsure how much is enough
- You do not know how lenders decide the maximum loan
- You are unclear which costs fall outside the purchase price
The situation
A first buy-to-let is less complicated than most people expect, but it is assessed on a completely different basis from a residential mortgage, which is where the confusion comes from.
The property has to pay for itself. Lenders calculate whether the rent covers the mortgage payment with a substantial safety margin, and that calculation — not your salary — usually sets the maximum loan.
Why the usual lenders say no
- Many lenders require you to already own your own home; first-time buyer landlords face a much narrower panel.
- Some apply a minimum personal income, commonly around £25,000, independent of the rent.
- A low-yielding property can fail the rental stress test even with a large deposit.
What usually works
02
Budgeting for the full cost
Stamp duty at the additional property rate, legal fees, a valuation, any immediate works, and a void allowance. The deposit is not the whole number.
03
Deciding personal or company ownership early
Changing your mind later is expensive, because moving a property into a company is a disposal for tax purposes. Speak to an accountant before you buy, not after.
04
Choosing the property for the numbers
A cheaper property in a higher-yielding area frequently borrows more easily than an expensive one in a low-yielding area, because rental cover is the binding constraint.
Roughly how the numbers look
| Typical minimum deposit | 25% of the purchase price |
| Rental cover | Rent stress-tested against the payment with a lender margin |
| Minimum income | Some lenders require around £25,000; others have none |
| Homeowner requirement | Many lenders prefer or require it |
Stamp duty on an additional property is a significant cost that first-time landlords routinely leave out of their calculations. These are examples to show the shape of a deal, not a quotation. Work out your own figures in the bridging calculator.
What we would need from you
- Details of the property and a rental appraisal from a local agent
- Proof of your deposit and its source
- Proof of income
- Details of your own home and its mortgage, if you have one
- Whether you intend to buy personally or through a company
- Details of existing credit commitments
Things that catch people out
- Void periods are real. Budget for the property being empty part of the year.
- Letting a property has legal obligations: gas safety, EPC, deposit protection, right to rent checks.
- Consent to let is not the same as a buy-to-let mortgage. If it is your former home, say so upfront.
Questions we get asked
How much deposit do I need for a first buy-to-let?
Usually at least 25% of the purchase price. Some lenders go to 20% at higher rates, but 25% opens up a much better range of products.
Do I need to own my own home first?
Many lenders require it, and first-time buyer landlords face a narrower panel with more conditions. It is possible without, but it is worth knowing before you start looking.
How do lenders decide how much I can borrow?
Primarily on the rent. They stress-test it against the mortgage payment with a margin on top, and that calculation usually sets the maximum rather than your personal income.
