7 Must-Have Apps for Property Investors in 2025

Running a rental portfolio from a phone once seemed more impressive in theory than it proved to be in day-to-day practice. Now, however, the right mix of apps can make a landlord’s operation genuinely more organised and accessible. Whether a portfolio contains one property or twenty, the difference between smooth management and continual administrative problems often comes down to the tools being used.

Making Tax Digital for Income Tax Self Assessment begins in April 2026 for landlords earning more than fifty thousand pounds, making properly maintained digital records more important than ever. The following seven apps are worth having in place for every property investor.

Sage: Financial Management and MTD Software

Sage provides the financial base for an effectively managed rental portfolio. It records rental income and allowable expenditure as it happens, keeps the digital records needed for MTD, and shows a landlord’s tax position across the year. This means quarterly filings and the annual self assessment return can rely on 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 ordinary record keeping. Its plans can suit landlords with portfolios of different sizes without demanding enterprise-level expenditure.

Why it matters: Up-to-date financial oversight and HMRC-recognised digital records underpin an efficiently managed property portfolio in the MTD era.

Plum: Financial Planning and Smart Savings App

Rental property can create uneven income, while a portfolio may also face voids, unexpected repair bills and substantial capital spending during any year. Managing that cash flow requires deliberate planning. Plum is a smart savings app that reviews income patterns and automatically allocates funds into dedicated pots for purposes such as tax liabilities, maintenance reserves or acquisition funds.

For landlords who want reserves to accumulate steadily during the year instead of being pulled together urgently when an invoice arrives, Plum introduces automated discipline without relying on willpower.

Why it matters: Building cash reserves methodically helps landlords avoid being caught out by void periods, unforeseen maintenance costs or tax bills before funds have been set aside.

Goodlord: Platform for Tenancy Management

Goodlord is a tenancy management platform that letting agents and landlords use to manage the administrative process from an offer through to move-in. Its single digital workflow covers referencing, contracts, utility registration and deposit protection. Landlords handling lettings themselves can use Goodlord to apply the structured process commonly used by leading agencies.

When a tenancy is established correctly at the outset, with documents signed, deposits protected and utilities registered clearly and audibly, disputes and end-of-tenancy complications are considerably less likely.

Why it matters: A structured and thoroughly documented tenancy process lowers dispute risk while providing the clear audit trail needed to support deductions or claims at the tenancy’s end.

Property Filter: Deal Sourcing and Investment Analysis Platform

Property Filter is a data platform that enables investors to assess the entire property market against defined investment requirements, including yield thresholds, property type, location and price point. Instead of searching portals manually and working out returns for every listing, landlords can see only deals matching their criteria, with the relevant calculated metrics displayed in advance.

For landlords aiming to expand a portfolio strategically rather than reactively, a structured platform for deal analysis cuts through unnecessary information and makes investment decisions both faster and more consistent.

Why it matters: Using data-led, systematic investment analysis rather than instinct supports stronger portfolio choices and lowers the chance of buying properties that perform below expectations.

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 detailed checks, including income verification through open banking, credit history, rental payment history and affordability assessments, usually within hours instead of days.

Canopy’s open banking income verification is especially useful because it identifies actual income rather than depending only on payslips. This can provide a clearer understanding of whether a prospective tenant can maintain the rent.

Why it matters: Detailed and timely tenant referencing reduces the likelihood of arrears and possession proceedings, while creating an evidence base for decisions that could later be challenged.

Rightmove Data Tools: Portfolio Valuation and Market Research

Beyond property searches, Rightmove’s data tools offer landlords market intelligence such as comparable local rental values, demand patterns, void-rate indicators and an overview of how a portfolio compares with its local market. Knowing whether rent is aligned with market rates, or whether a property is becoming more difficult to let, directly informs financial planning.

Reliable market data is one of the most valuable resources available to landlords deciding where to invest next or when to reassess rents for current properties.

Why it matters: Decisions on rent levels and portfolio growth supported by data are more dependable than instinct and can directly influence long-term returns.

Homeppl: Referencing for International and Non-Standard Tenants

In university cities and urban areas with high numbers of international tenants, students or applicants with non-traditional income, conventional referencing platforms can sometimes struggle to deliver a dependable assessment. Homeppl focuses on applicants outside standard criteria, drawing on alternative data sources and guarantor matching to give landlords confidence in tenancies that may otherwise be difficult to evaluate.

Homeppl addresses a real gap for landlords seeking access to a wider group of reliable tenants without assuming disproportionate risk.

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

Common Questions

From when does 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 more than thirty thousand pounds will follow from April 2027. Landlords below these limits are not currently included, although digital organisation remains sensible because the requirements are expected to broaden further over time.

Which costs may landlords lawfully deduct from rental income?

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

Is an accountant still necessary when using property finance software?

Good software enables many landlords with uncomplicated portfolios to manage their own tax matters successfully. Accountants are most valuable to landlords facing increasing portfolio complexity, considering incorporation, handling capital gains tax on disposal or seeking a professional review of an 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 will usually lower their fees.

Should a rental portfolio be incorporated into a limited company?

For some landlords, especially those with larger portfolios or higher incomes, incorporation may provide tax benefits. However, it also involves substantial financial and legal factors, including effects on current mortgage terms and stamp duty when transferring property. Incorporation is not automatically advantageous, so professional advice tailored to the individual circumstances is needed before taking action.

What steps should landlords take 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 develop the necessary routine and hold accurate records for quarterly submissions well before the requirement begins, avoiding a hurried transition.
