Buying Your First Buy-to-Let: A Checklist for New Landlords

Buying your first buy-to-let property is exciting and daunting in roughly equal measure. The route from "I'm thinking about it" to "the first month's rent landed in my account" has 30+ decision points; getting two or three wrong can cost you tens of thousands. This checklist covers everything you need to think about before, during, and after your purchase — including the realistic 2026 numbers, the regulatory layers a first-time landlord usually doesn't see coming, and the honest tradeoffs between BTL strategies. Read it once before you start property-hunting and again after you've found something you're considering.

Before you start property-hunting (the foundations)

Decide if BTL is the right vehicle for you

BTL works for some investor profiles and not others. Honest gut check:

• Are you happy to commit at least 3–5 years before you'd consider selling? Property is illiquid; in-and-out moves usually destroy capital.
• Can you afford to lose 6–12 months of rent in a single bad tenant + eviction scenario?
• Are you OK being on the hook for repairs at unsocial hours (or paying an agent / contractor 10–15% to absorb that)?
• Do you understand that Section 24 mortgage interest changes mean your taxable rental "profit" can be much higher than your bank balance shows?

If "no" to any of these, consider alternatives — REITs, pension contributions, or stocks-and-shares ISAs — before sinking 25% of your liquid net worth into a single illiquid property.

Decide ownership structure

Personal name vs limited company is the single biggest tax-impacting choice. Headlines:

• Personal name (sole / joint): Simpler, cheaper to set up, all rental profit added to your income tax band. Section 24 hits higher-rate taxpayers hard.
• Limited company: Mortgage interest fully deductible against Corporation Tax (19–25%). Higher mortgage rates than personal-name BTL (typically 0.5–1% premium). Profits can be retained inside the company tax-deferred. Extracting income via dividends adds 8.75–39.35% dividend tax depending on your income band.
• Joint with spouse: Income split via Form 17 election can shift income into a lower-band spouse — useful when one of you is basic-rate and the other higher-rate.

Get the financing in place

• Buy-to-let mortgage Agreement in Principle (AIP) — typically 25% deposit minimum (some lenders accept 20% with stricter rental coverage). Premium products at 25% LTV; rate scales with LTV.
• Rental coverage ratio: BTL lenders need rental income of 125% (basic-rate landlords) to 145% (higher-rate landlords / limited companies) of mortgage payment at a stress-tested rate (typically 5.5–6.5%, not the actual rate).
• Personal income evidence — 3 months' payslips + 3 months' bank statements minimum.
• Property type restrictions — many BTL lenders won't lend on flats above commercial premises, ex-local-authority flats above 4 storeys, studio flats below 30 m², or studio flats inside HMOs. Check before you offer.
• Use a specialist BTL mortgage broker — whole-of-market access typically gets a better rate than your high-street BTL lender.

Calculate your yield (don't skip this)

Use the free rental yield calculator to check the numbers stack up. Rough sanity targets for 2026:

• Gross yield: 6.5%+ for the deal to be worth pursuing in most regions
• Net yield (after operating costs but before tax): 4.5%+
• Cash-on-cash return on invested cash: 7–10% for the leverage to be worth the risk

If your gross yield is below 5%, the property is being valued for capital gains rather than income — fine if that's your strategy, but be honest about it.

Budget for the full cost stack

Use the stamp duty calculator for SDLT (remember the 5% additional property surcharge). On a £200,000 BTL purchase, expect around £7,500 SDLT alone. Total transaction costs (SDLT + legal + survey + mortgage arrangement + insurance setup) typically run 7–10% of purchase price for first-time landlords. A £200k property realistically needs £64k–£68k cash for the 25% deposit + transaction costs combined.

Research the area properly

• Rental demand — Rightmove + Zoopla + OpenRent listings already in the postcode. How many active listings? How long have they been active? Healthy market = listings rotate within 2–3 weeks.
• Local rental yields — see the regional yield hotspots guide for current ranges
• Tenant demographics — students, professionals, families, social housing. Different demographics need different property types.
• Growth potential — local council strategic plans, transport links coming, employer expansions. Don't just buy yesterday's hotspot.
• Article 4 directives + selective licensing — if the postcode is in an Article 4 area, you can't convert a single dwelling to an HMO without planning permission. Check the council website.
• EPC requirement landscape — if you're planning to hold to 2030, properties currently rated D or below need £5–£15k of upgrade work to comply with the proposed C minimum.

During the purchase

Get the right survey

• Mortgage valuation only — minimum required by the lender. Tells you almost nothing about the property's condition. Avoid as your sole survey.
• RICS Level 2 (Homebuyer Report) — £400–£700. Suitable for properties built post-1950 in standard condition.
• RICS Level 3 (Building Survey) — £700–£1,500. Required for pre-1900s properties, listed buildings, anything with visible structural concerns, or properties you intend to refurb.

Skip the survey to save £600 and you risk a £20,000 surprise. Always survey.

Compliance investigation pre-completion

• EPC current rating — check the government register at find-energy-certificate.gov.uk. Below E = you can't legally let; below C = budget for the 1 October 2030 PRS MEES standard or gather exemption evidence.
• Electrics — budget £150–£300 for an EICR if the existing one expires within 12 months OR the consumer unit is pre-2018 type. Add £600–£3,000 if the EICR returns C2 or C3 codes requiring remedial work.
• Gas — boiler age + last service date. Boilers 12+ years old often need £2,000–£3,500 replacement. New A-rated combi adds 3–6 EPC points alongside.
• Roof condition — flagged on the survey. Major roof work £4,000–£12,000 depending on size + complexity.
• Damp — survey will flag readings. Treat damp before letting; mould-related illness claims are a real legal exposure.
• Asbestos — pre-2000 properties may contain asbestos. Survey identifies; specialist removal £500–£3,000 per area depending on type.

Insurance before completion

Arrange landlord buildings insurance to take effect from the moment of completion (your solicitor needs the policy reference). Standard residential cover usually voids the moment you let. See the landlord insurance guide for what cover you actually need.

Solicitor + tenant ready before completion

• Use a property solicitor who has BTL experience — they know the searches and clauses that matter
• Have your tenancy agreement template drafted (standard AST template + customisations for your specific property)
• If buying with sitting tenants, request copies of all current tenancy agreements + certificates BEFORE exchange

Before your first tenant moves in

Mandatory pre-tenancy compliance

• Gas Safety Certificate — must be in place before the tenancy starts. Renewed every 12 months. Engineer must be Gas Safe registered.
• EICR — required for all new tenancies since June 2020. Renewed every 5 years (or as recommended on the report).
• EPC — must be provided to prospective tenants before viewing. Valid 10 years.
• Smoke alarms — fitted on every storey containing living accommodation. Tested at start of every new tenancy. Mains-wired or 10-year battery preferred.
• Carbon monoxide alarms — required in every room with a gas, oil, or solid-fuel appliance (including gas boilers in airing cupboards). Tested at start of every new tenancy.
• Deposit protection — register the deposit with DPS, MyDeposits, or TDS within 30 days of receipt. Penalty for late or missed protection is 1×–3× the deposit, payable to the tenant.
• Prescribed Information — serve to tenants within 30 days of receiving the deposit. Must include scheme details, contact info, dispute process.
• Right to Rent checks — verify every adult tenant's right to rent (England only). Civil penalty up to £20,000 per illegal occupant if missed.
• How to Rent guide — provide the latest government version to tenants before move-in (England only). It remains a core document-pack requirement after Section 21 abolition.
• Selective licensing — if the property is in a designated area, the licence must be in place before letting. Operating without a licence = £30,000+ civil penalty.
• HMO licensing — if the property is an HMO (5+ unrelated occupants from 2+ households OR mandatory licensing area), the HMO licence must be in place before letting.

Operational setup

• Landlord bank records ready for manual or CSV reconciliation; automatic Open Banking remains provider-gated
• Inventory created with photos at check-in
• Tenant signed on the tenancy agreement
• First month's rent + deposit received
• Prescribed Information sent
• Keys handed over
• Welcome pack with utility supplier info, neighbour intro, bin day, parking rules

Ongoing management — the first 12 months

• Track rent payments via Open Banking and chase arrears within 48 hours of any miss
• Keep digital records of all expenses (Tendmere's receipt OCR handles this from photos)
• Maintain a property file with every certificate, inspection report, contractor invoice, tenant communication
• Set calendar reminders for certificate renewals (Gas Safety annually, EPC at year 9, EICR at year 4, deposit-protection records, Right to Rent re-checks for time-limited cases)
• Build a maintenance reserve — 1% of property value per year is the standard rule of thumb; 0.7% for newer properties, 1.5% for pre-1950 builds
• Register for MTD ITSA if your combined SE + property income exceeds £50,000 (April 2026), £30k (April 2027), or £20k (April 2028)
• Mid-tenancy inspection at month 6 — gives you visibility on how the property's being treated and surfaces issues early

Common first-time-landlord mistakes

• Buying without research because "London always goes up". Capital growth is unpredictable; income is the foundation. Buy on income.
• Assuming the rent will cover everything. Rent covers mortgage + operating costs + tax — there's typically £100–£300/month of net cash on a typical BTL after all of those. Building a portfolio takes time.
• Skipping the survey. Already covered. Always survey.
• Skipping insurance because the standard residential policy "transferred over". It didn't. The first claim will be denied.
• Believing a friend / sourcer / "investment club" who promises 12%+ yields with low risk. If the deal sounds too good, it is.
• Over-leveraging. A 90% LTV BTL with no cash reserve is one missed payment from forced sale. 70–75% LTV with 6 months' mortgage in reserve is the resilient configuration.
• Inadequate tenant referencing. Skip the £30 reference and the bad-tenant cost is £3,000–£10,000.
• Setting up DIY tenancy agreements from generic templates. Use NRLA / OpenRent / shelter-vetted templates, not Reddit downloads.
• Trying to do everything by spreadsheet. Time + error cost exceeds £190/year of software within 6 months.

The honest first-year reality

Most first-time landlords find year 1 harder than expected — the cash flow is tighter than the spreadsheet suggested, the time commitment is more than expected, and one of the smaller compliance items always catches them. By year 2 the rhythm settles and most landlords find it sustainable. By year 3, decisions about adding a second property become realistic.

Set up for success

The landlords who succeed long-term are the ones who treat property as a business from day one. That means careful records, appropriate insurance, compliance review, and dependable tools. Tendmere's controlled beta takes no card payment and supports reviewed CSV exports. Build the property record step by step and attach source evidence before treating it as complete.
