Seven Essential Apps for Property Investors to Use in 2025

Running a rental portfolio from a phone used to seem more impressive in theory than it was useful in reality. Now, however, the right selection of apps can make a landlord’s operation considerably more organised and accessible. Whether a landlord owns a single property or twenty, smooth portfolio management rather than recurring administrative problems usually comes down to having the right systems in place.

Making Tax Digital for Income Tax Self Assessment will begin in April 2026 for landlords earning more than fifty thousand pounds. As a result, the need to maintain well-organised digital records has become increasingly urgent. Below are seven apps property investors should have installed and in use.

Sage: Financial Management and MTD Software

Sage provides the financial base for an effectively managed rental portfolio. It monitors rental income and allowable costs as they arise, keeps the digital records needed for MTD, and calculates tax position across the year. This means quarterly submissions and the annual self assessment return can be prepared using accurate, up-to-date information.

For landlords nearing the MTD for ITSA threshold, Sage simplifies the administration involved in quarterly reporting by making it part of everyday record keeping. Its plans can suit landlords with portfolios of different sizes without demanding enterprise-level investment.

• Tracks rental income and allowable expenses in real time
• Maintains HMRC-recognised digital records for MTD
• Calculates tax position throughout the year
• Supports quarterly submissions and annual self assessment returns with current data
• Offers plans that can scale for different portfolio sizes

Why it matters: In the MTD era, real-time oversight of finances and HMRC-recognised digital records form the basis of an efficiently managed property portfolio.

Plum: Smart Savings and Financial Planning App

Property investment can produce uneven income, while a portfolio may also face voids, unexpected repair bills and substantial capital expenditure during a single year. Managing those cash flow demands requires deliberate financial planning. Plum is a smart savings app that reviews income patterns and automatically allocates money to dedicated pots, including funds for tax liabilities, maintenance reserves or acquisitions.

For landlords who want reserves to build steadily over the year instead of scrambling to assemble cash when an invoice arrives, Plum offers automated discipline without relying on willpower.

Why it matters: Building cash reserves systematically helps prevent landlords from being caught short by void periods, unexpected maintenance costs or tax bills before the relevant money has been set aside.

Canopy: Platform for Tenant Referencing

Choosing an unsuitable tenant can be among the most expensive errors a landlord makes. Canopy is a modern tenant referencing platform offering thorough checks, including open banking-based income verification, credit history, rental payment history and affordability assessments, usually within hours rather than days.

Canopy’s open banking approach to verifying income is especially useful because it identifies actual income rather than depending only on payslips. This can provide a more precise assessment of whether a prospective tenant can continue meeting the rent.

Why it matters: Thorough and rapid tenant referencing can reduce the likelihood of arrears and possession proceedings, while supplying evidence for decisions that could later be challenged.

Property Filter: Deal Sourcing and Investment Analysis Platform

Property Filter is a data platform through which investors can assess the entire property market against their own investment requirements, including yield thresholds, property type, location and price point. Instead of searching portals manually and working out returns for every property, landlords can identify only those deals meeting their criteria and view calculated metrics in advance.

For landlords seeking to expand their portfolio strategically instead of reacting to opportunities as they arise, a structured deal analysis platform cuts through unnecessary information and makes investment decisions more consistent and efficient.

Why it matters: A systematic, data-led approach to investment analysis supports stronger portfolio decisions and lowers the chance of buying properties that fall short of expectations.

Goodlord: Platform for Managing Tenancies

Goodlord is a tenancy management platform that letting agents and landlords use to manage the administrative process from offer through to move-in. Its single digital workflow covers referencing, contracts, utility registration and deposit protection. Landlords handling their own lettings without an agent can use Goodlord to apply the same organised, professional process used by leading agencies.

When tenancies are correctly established from the outset, with documents signed, deposits protected and utilities registered clearly and audibly, they are far less likely to create disputes or complications at the end of the tenancy.

Why it matters: A professionally documented tenancy process lowers dispute risk and produces the clear audit trail needed to support deductions or claims at the end of a tenancy.

Rightmove Data Tools: Portfolio Valuation and Market Research

Rightmove’s data tools offer more than property search functionality. They give landlords market intelligence on comparable local rental values, demand patterns, void rate indicators and how a portfolio compares with its surrounding market. Knowing whether rents reflect market rates, or whether a property is becoming more difficult to let, directly informs financial planning.

Reliable market information is one of the most useful resources for landlords deciding where to invest next or when to reassess rents across existing properties.

Why it matters: Decisions on rent levels and portfolio growth made using data are more dependable than those based on instinct, with a direct effect on long-term returns.

Homeppl: Referencing for International and Non-Standard Tenants

In university cities and urban areas with significant numbers of international tenants, students or applicants with non-traditional income, standard referencing platforms may not always deliver a dependable assessment. Homeppl focuses on referencing applicants outside standard criteria. It uses alternative data sources and guarantor matching to give landlords confidence when assessing tenancies that might otherwise be difficult to evaluate.

Homeppl addresses a genuine need for landlords aiming to reach a wider group of reliable tenants without accepting disproportionate risk.

Why it matters: Completely excluding non-standard applicants narrows the potential tenant pool. Specialist referencing enables landlords to assess these applicants properly rather than making assumptions.

Frequently Asked Questions

From when will MTD for Income Tax Self Assessment affect landlords?

From April 2026, MTD for ITSA applies to landlords whose combined income from property and self employment exceeds fifty thousand pounds. Those earning above thirty thousand pounds will follow from April 2027. Landlords under these limits are not currently within scope, although organising records digitally now remains sensible because the requirements are expected to expand further over time.

Which expenses may landlords validly offset against rental income?

Permitted expenses include letting agent charges, property repairs and maintenance, landlord insurance premiums, accountancy costs, ground rent and service charges, selected utility costs during void periods and certain legal fees. For most landlords, mortgage interest relief is restricted to a twenty percent tax credit rather than being fully deductible. Keeping accurate digital records throughout the year helps ensure every allowable cost is captured and reported correctly.

Is an accountant necessary when using property finance software?

Many landlords with uncomplicated portfolios handle their own tax responsibilities effectively using suitable software. Accountants provide the greatest value to landlords facing increasing portfolio complexity, considering incorporation, dealing with capital gains tax on disposal or seeking a professional review of their annual return. Keeping records clean throughout the year with software such as Sage generally reduces the time an accountant must spend on the affairs, which usually lowers their fees.

Should a rental portfolio be incorporated into a limited company?

For some landlords, especially those with higher incomes or larger portfolios, incorporation may offer tax advantages. However, the choice also carries substantial financial and legal considerations, including effects on existing mortgage terms and stamp duty on transfer. Incorporation is not automatically advantageous, so professional advice tailored to individual circumstances is needed before taking action.

What should landlords do to prepare for MTD before April 2026?

The key action is to adopt HMRC-recognised software and begin recording every item of rental income and expenditure digitally now. Landlords who start before the deadline will have developed the necessary habits and built accurate records for quarterly submissions well before the obligation starts, rather than dealing with a rushed changeover.
