Check the numbers before you make an offer
Buying your first rental property is both a purchase and an ongoing responsibility. Check your total cash budget, the property’s likely rent and condition, and whether a mortgage route fits your circumstances before you commit to a price.
This guide is for someone becoming a landlord for the first time, whether you already own your home or have never owned a property.
First-time landlord or first-time property buyer?
You can be a first-time landlord even if you already own the home you live in. If you have never owned any property, say so at the outset: some lenders assess that application differently. Our first-time property buyer buy-to-let guide covers that distinct situation.
Neither label decides whether a mortgage is available. The lender will consider the applicant, property, rent, deposit, credit position and proposed letting arrangement. If you plan to move out of your current home and let it, ask about let-to-buy or consent to let instead of assuming this purchase route applies.
Work out the cash you need, beyond the deposit
There is no deposit percentage that fits every lender, property and applicant. Before you offer, estimate the deposit you can actually use after keeping money back for buying costs and a reserve. A low monthly mortgage payment will not help if the initial cash is short.
Costs to complete
Allow for property transaction tax, conveyancing, survey and valuation, mortgage product and adviser fees where applicable, and any immediate work needed before letting. Check leasehold service charges and ground rent if relevant.
Cash to keep
Plan for repairs, insurance, agent costs, periods without rent, arrears and future rate changes. Keep a reserve that reflects the property and your own commitments; a lender’s calculation is not a household emergency fund.
Property transaction taxes depend on where the property is and who is buying. SDLT guidance covers England and Northern Ireland; Scotland has LBTT and Wales has LTT. A conveyancer or tax adviser should calculate the tax for the actual ownership and transaction. Do not assume first-time-buyer relief applies to a property you intend to let.
Test the property and the rent together
Look at comparable properties that have actually let, not just advertised asking rents. Check how long similar homes remain empty, what tenants can reasonably expect, and what work is needed before the first tenancy. A survey, valuation and conveyancer’s enquiries may reveal issues that change your budget or the lender’s view.
Property fit
Ask about condition, title, lease terms, planning, access, safety, energy performance and any local licensing. A house in multiple occupation needs its own checks; see the existing HMO mortgage route if shared occupancy is planned.
Real income
Start with a cautious rent estimate. Subtract voids, repairs, agent charges, insurance, service charges, tax and mortgage payments to see what cash might remain. Gross rental yield is a comparison measure, not profit or a promise of capital growth.
A useful question before offering: if the rent is lower, the property is empty for a spell or the survey finds work, can you still complete and run it without relying on a quick sale?
Check mortgage fit before you commit
A buy-to-let lender may assess your deposit and source of funds, personal circumstances, credit history, property type, expected rent and landlord experience. Some lenders ask about personal income or existing homeownership; others have different criteria. There is no market-wide minimum salary, age limit or property-value floor. The criteria guide explains the main variables in more detail.
The lender’s rental affordability or stress calculation uses its own assumptions. It is different from your contractual monthly payment and from cash left after the property’s real costs. Passing that test does not guarantee a mortgage offer or a profitable rental.
Interest-only or repayment?
With interest-only borrowing, the capital normally remains due at the end of the term, so you need a credible repayment plan. A repayment mortgage reduces capital as scheduled payments are made, but may have higher monthly payments. Compare the structure against your actual cash flow.
Compare the whole deal
Look beyond the initial rate: product and adviser fees, valuation and legal costs, the rate after the deal, and early repayment charges can change the total cost. See the existing rates and costs page for the current comparison route.
The regulatory treatment of business and consumer buy-to-let can differ. An adviser should explain which route and protections apply to your circumstances.
Choose the ownership route and check local letting rules
Buying personally or through a company changes the mortgage, tax, legal and administration picture. A company is not automatically more tax-efficient or suitable. Discuss ownership and tax with an accountant or tax adviser and solicitor before committing; the limited-company mortgage guide covers borrowing questions.
Landlord duties differ across the UK and can change. Check the rules for the property’s nation and council area before letting, including registration or licensing, safety and repair standards, tenancy documents, deposits and energy performance. England’s current landlord overview reflects the Renters’ Rights Act changes effective from 1 May 2026. Right-to-rent checks apply to residential letting in England; do not assume they apply in Scotland, Wales or Northern Ireland. Welsh landlord guidance, Scotland’s landlord guidance and Northern Ireland’s registration guidance illustrate different requirements.
In England, landlords cannot reject applicants simply because they receive benefits or have children under the current rental-discrimination rules. Seek legal or letting-agent advice on the actual tenancy and apply lawful, consistent checks. Mortgage advice does not replace tax, conveyancing or landlord-law advice.
A sensible order for the first purchase
- Set your limit. Add purchase costs, likely works and a cash reserve to the deposit. Decide what you can afford if the property has no rent for a period.
- Check the proposed property. Gather asking price, expected rent, location, property type and any known lease, licence or repair issue.
- Discuss the mortgage route. Explain whether you already own a home, how you will buy, your deposit source and your deadline. Ask what a lender needs before you pay for valuation or legal work.
- Use the survey and conveyancing checks. Confirm condition, title, taxes and any restrictions on letting before exchange or the equivalent binding stage.
- Prepare to let. Arrange the correct insurance, safety and tenancy steps for the property’s location. The existing landlord-insurance page is a separate protection route.
No checklist makes a purchase safe or guarantees finance. Allow time for lender, valuer and legal questions, especially if completion has a fixed deadline.
See how clients describe the advice
For a first rental purchase, it helps to know how an adviser explains options, costs and the next steps. These reviews describe Count Ready’s service; they do not predict a mortgage decision or investment result.
Discuss your first rental purchase
Tell Count Ready whether you already own a home, where and what you plan to buy, the approximate price, deposit and expected rent, and any offer or completion deadline. The team can discuss what mortgage information is needed next. Keep bank statements and identity documents for a secure later step.
First rental purchase questions
Can I get a buy-to-let mortgage as a first-time landlord?
Possibly. Lenders consider the applicant, property, expected rent, deposit and their current criteria. Some treat people who have never owned property differently from homeowners buying their first rental. Give the adviser your ownership history and proposed letting plan so the right route can be checked.
How much deposit will I need?
It depends on the lender, product, property and your circumstances. Budget for purchase taxes, fees, work and a reserve as well as the deposit. A lender’s maximum loan amount is not a recommendation to use all your available cash.
Does passing a rental calculation mean the property will make money?
No. A lender’s rental test uses underwriting assumptions and may not equal the contractual payment. Your cash position also depends on voids, repairs, fees, insurance, tax and rate changes. Test those costs separately.
Does first-time-buyer tax relief apply to a rental purchase?
Usually not for a property bought to let. In England and Northern Ireland, HMRC’s first-time-buyer SDLT relief requires the buyer to intend to occupy the property as their main residence. Wales has no first-time-buyer LTT relief, and Scotland has separate LBTT rules. Ask your conveyancer or tax adviser to check your transaction before you commit.
