7 Apps Property Investors Should Keep on Their Phone in 2025

Managing a rental property portfolio through a smartphone once seemed more practical in theory than it was in reality. With the right selection of apps now available, however, landlords can make their operations far more accessible, organised, and efficient. Whether an investor owns a single rental property or a portfolio of twenty, having appropriate digital tools in place can make the difference between straightforward management and persistent administrative problems.

With Making Tax Digital for Income Tax Self Assessment taking effect from April 2026 for landlords earning more than fifty thousand pounds, maintaining properly organised digital records is becoming increasingly important. The following seven apps can support property investors across the financial, tenancy, research, and planning aspects of portfolio management.

1. Sage: Financial Management and MTD Software

Sage provides the financial infrastructure needed to keep a rental portfolio organised. It records rental income and allowable expenses as they arise, maintains the digital records required for MTD, and tracks tax position throughout the year, helping ensure that quarterly submissions and the annual self assessment return are prepared using accurate and current information.

For landlords approaching the MTD for ITSA threshold, Sage makes quarterly reporting a more manageable extension of everyday record keeping rather than a separate administrative challenge. Its plans are designed to accommodate landlords with different portfolio sizes without requiring investment in enterprise-level software.

Why it matters: Up-to-date financial oversight combined with HMRC-recognised digital records provides a strong foundation for managing a property portfolio effectively under MTD.

2. Canopy: Digital Tenant Referencing Platform

Choosing an unsuitable tenant can become one of the most expensive errors a landlord encounters. Canopy provides a modern approach to tenant referencing, carrying out comprehensive checks that include credit history, rental payment records, affordability assessments, and income verification through open banking, generally within hours rather than several days.

Its open banking approach to verifying income is especially useful because it provides evidence of actual income instead of depending entirely on payslips. This can give landlords a clearer understanding of whether a prospective tenant is financially able to maintain the required rent.

Why it matters: Fast and thorough tenant checks can lower the likelihood of arrears and possession proceedings while providing evidence to support decisions that could subsequently be challenged.

3. Property Filter: Deal Sourcing and Investment Analysis Platform

Property Filter is a data-driven platform that enables investors to assess the wider property market according to defined investment requirements, including location, property type, price point, and yield thresholds. Instead of manually reviewing listings across portals and calculating returns individually, landlords can use Property Filter to identify opportunities that meet their criteria and view the relevant calculated metrics immediately.

For investors seeking to expand their portfolios according to a deliberate strategy rather than responding to opportunities as they arise, structured deal analysis can reduce unnecessary searching while making investment decisions more consistent and efficient.

Why it matters: Applying a systematic, data-led approach to property analysis can improve portfolio decisions and reduce the likelihood of purchasing properties that fail to perform as expected.

4. Goodlord: Digital Tenancy Administration Platform

Goodlord helps letting agents and landlords manage the administrative process from an accepted offer through to a tenant moving in. Referencing, tenancy contracts, utility registration, and deposit protection can all be handled through one digital workflow. Landlords who manage properties without a letting agent can therefore use a structured process similar to those followed by professional agencies.

When tenancy documentation is completed correctly from the outset, deposits are properly protected, and utilities are registered through a clear and auditable system, landlords are less likely to encounter avoidable disagreements or complications when the tenancy concludes.

Why it matters: A properly documented and professional tenancy setup can reduce dispute risk and establish the clear audit trail required to support deductions or claims at the end of a tenancy.

5. Plum: Automated Savings and Financial Planning App

Rental property investment can create uneven cash flow, particularly when portfolios experience void periods, unexpected repairs, or substantial capital expenditure during a particular year. Plum is a smart savings application that reviews income patterns and automatically allocates money into dedicated pots for purposes such as tax liabilities, maintenance reserves, or future acquisitions.

Landlords who prefer to build financial reserves steadily throughout the year rather than finding funds at short notice when a major expense becomes payable can use Plum to automate that saving discipline.

Why it matters: Consistently building cash reserves can help landlords remain prepared for vacancies, unforeseen maintenance expenditure, and tax bills before those costs become immediately due.

6. Rightmove Data Tools: Property Market Research and Portfolio Valuation

Rightmove's data tools extend beyond searching for available properties by providing landlords with useful market information, including comparable rents in particular areas, tenant demand trends, indicators relating to void rates, and insight into how properties within a portfolio compare with the surrounding market. Knowing whether existing rents reflect prevailing market levels, or whether a property is becoming more difficult to let, can directly influence financial planning.

For landlords assessing potential locations for their next acquisition or deciding when existing rents should be reviewed, dependable market information can provide valuable evidence for making those decisions.

Why it matters: Decisions about rental pricing and portfolio expansion that are supported by market data are generally more dependable than relying on instinct alone and can directly affect long-term investment returns.

7. Homeppl: Referencing for International and Non-Standard Tenants

In university locations and urban markets with large numbers of international tenants, students, or applicants whose income does not follow conventional patterns, traditional referencing systems may struggle to reach a dependable assessment. Homeppl focuses on applicants who sit outside standard referencing criteria, using alternative data sources and guarantor matching to help landlords evaluate tenancies that might otherwise be difficult to assess confidently.

For landlords interested in considering a wider range of potentially reliable tenants without accepting disproportionate risk, Homeppl addresses an area that conventional referencing may not always cover effectively.

Why it matters: Automatically rejecting applicants who do not meet conventional criteria reduces the available tenant pool. Specialist referencing allows those applicants to be assessed using appropriate information rather than leaving landlords to make assumptions.

Frequently Asked Questions

At what point does MTD for Income Tax Self Assessment apply to 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 become subject to the requirements from April 2027. Landlords whose income remains below these limits are not currently included, although establishing digital record keeping in advance remains advisable because the requirements are expected to expand further over time.

Which expenses are landlords allowed to deduct from rental income?

Permitted expenses include letting agent charges, maintenance and property repairs, landlord insurance premiums, accountancy costs, ground rent and service charges, certain utility expenses incurred during void periods, and some legal fees. For most landlords, mortgage interest relief is now provided as a twenty percent tax credit rather than being treated as a complete deduction. Maintaining accurate digital records throughout the year helps ensure that every allowable expense is recorded and reported correctly.

Is an accountant necessary when property finance software is being used?

Landlords with relatively straightforward portfolios can often handle their own tax responsibilities successfully when supported by suitable software. Professional accountancy advice becomes particularly valuable when a portfolio grows more complex, when incorporation is being considered, when capital gains tax arises from a disposal, or when a landlord wants an expert review of the annual return. Maintaining organised records throughout the year with software such as Sage can also reduce the amount of time an accountant must spend reviewing the finances, which will usually lower the associated fees.

Should a rental property portfolio be incorporated into a limited company?

Operating through a limited company can provide tax benefits for some landlords, especially those with higher incomes or larger property portfolios. However, incorporation also involves substantial legal and financial considerations, including possible consequences for existing mortgage arrangements and stamp duty when properties are transferred. It is therefore not automatically the most advantageous option, and professional advice based on the landlord's individual circumstances should be obtained before proceeding.

What should landlords do to get ready for MTD ahead of April 2026?

A key preparation step is moving onto HMRC-recognised software and beginning to maintain digital records for all rental income and expenditure as early as possible. Landlords who establish this process before the deadline can develop consistent record-keeping habits and build the accurate information required for quarterly submissions well before the rules take effect, avoiding the difficulties of making the transition at the last minute.
