Seven Essential Apps for Property Investors to Keep on Their Phone in 2025

Running a rental portfolio from a smartphone used to seem more impressive in theory than it proved to be day-to-day. With the right set of apps now available, however, landlords can make their operations genuinely more organised and easier to access. Whether a landlord owns a single property or twenty, smooth portfolio management rather than recurring administrative problems usually comes down to having suitable systems in place.

Making Tax Digital for Income Tax Self Assessment will apply from April 2026 to landlords earning more than fifty thousand pounds. As a result, the need to maintain properly organised digital records is now more urgent than ever. These are seven apps property investors should have ready to use.

1. Sage: MTD Software and Financial Management

Sage provides the financial base for an efficiently run rental portfolio. It records rental income and allowable expenditure as it happens, keeps the digital records needed for MTD, and monitors tax liability 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 income threshold, Sage simplifies the administration involved in quarterly reporting by making it part of ordinary record-keeping. Its plans can accommodate 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
Offers plans suited to different portfolio sizes

Why it matters: In the MTD era, real-time financial insight and HMRC-recognised digital records underpin an effectively managed property portfolio.

2. Property Filter: Deal Sourcing and Investment Analysis Platform

Property Filter is a data platform through which investors can assess the whole property market against their chosen investment requirements, including yield thresholds, property type, location and price point. Instead of searching portals manually and working out potential returns for every listing, landlords can see only the opportunities matching their criteria, alongside the relevant calculated metrics.

Landlords seeking to expand their portfolios strategically rather than reactively can use a structured deal analysis platform to cut through irrelevant options. It also makes investment decisions more efficient and consistent.

Screens the property market using defined investment criteria
Filters by yield thresholds, property type, location and price point
Identifies deals that meet a landlord's requirements
Displays calculated investment metrics upfront

Why it matters: Applying data-led investment analysis rather than relying on instinct supports stronger portfolio decisions and lowers the chance of buying properties that perform below expectations.

3. Canopy: Platform for Tenant Referencing

Selecting an unsuitable tenant can be among the most expensive errors a landlord makes. Canopy is a contemporary tenant referencing platform offering detailed checks, including income verification through open banking, credit history, rental payment history and affordability assessments. These checks are typically completed within hours rather than days.

Canopy's use of open banking for income verification is particularly useful because it reflects actual income instead of depending only on payslips. This provides a clearer indication of whether a prospective tenant can maintain the rent.

Verifies income through open banking
Reviews credit history
Assesses rental payment history
Evaluates affordability, typically within hours rather than days

Why it matters: Thorough and timely tenant checks reduce the likelihood of arrears and possession proceedings, while creating evidence for decisions that could be challenged later.

4. Plum: Smart Savings and Financial Planning App

Income from property investment is often uneven. Managing cash flow across a portfolio with possible void periods, unplanned maintenance expenses and substantial capital expenditure in any year calls for deliberate financial planning. Plum is a smart savings app that reviews income patterns and automatically allocates money to purpose-specific pots, such as tax liabilities, maintenance reserves or acquisition funds.

For landlords who prefer reserves to grow steadily during the year, rather than having to gather funds quickly when an invoice arrives, Plum supplies automated discipline without depending on willpower.

Analyses patterns in income
Automatically moves money into purpose-specific savings pots
Supports funds for tax obligations
Helps build maintenance reserves and acquisition funds

Why it matters: Building cash reserves systematically helps prevent landlords being caught short by voids, unforeseen maintenance expenses or tax bills before sufficient funds have been set aside.

5. Rightmove Data Tools: Market Research and Portfolio Valuation

Rightmove's data tools offer more than property searching. They give landlords market intelligence on comparable rental values in particular locations, demand patterns, void rate indicators and the position of their own portfolio in relation to the local market. Knowing whether rents remain at market level, or whether a property is becoming more difficult to let, can directly influence financial planning.

Reliable market information is one of the most valuable resources for landlords deciding where to invest next or whether rents should be reviewed on existing properties.

Provides comparable rental values for specific areas
Tracks local demand trends
Includes void rate indicators
Shows how a portfolio compares with its local market

Why it matters: Decisions on rent levels and portfolio growth are more dependable when informed by data rather than instinct, with a direct effect on long-term returns.

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

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

Homeppl addresses a clear need for landlords aiming to access a wider group of dependable tenants without accepting disproportionate risk.

Assesses international tenants, students and applicants with non-traditional income
Uses alternative data sources
Provides guarantor matching
Supports assessment of applicants outside standard referencing criteria

Why it matters: Refusing all non-standard applicants narrows the available tenant pool. Specialist referencing allows landlords to assess such applicants properly instead of making assumptions.

7. Goodlord: Tenancy Management Platform

Goodlord is a tenancy management platform used by letting agents and landlords 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 lettings themselves can use Goodlord to apply the same structured and professional process used by leading agencies.

When tenancies are established properly at the outset, with documents signed, deposits protected and utilities registered in a clear, auditable manner, disputes and complications at the end of the tenancy are considerably less likely.

Manages the journey from offer to move-in
Supports tenant referencing
Handles contracts, utility registration and deposit protection
Creates a single digital tenancy workflow

Why it matters: Setting up tenancies professionally and maintaining clear documentation lowers dispute risk while providing the audit trail needed to support deductions or claims at the end of a tenancy.

Frequently Asked 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. Landlords with income above thirty thousand pounds will follow from April 2027. Those below these limits are not currently within scope, although it remains sensible to organise records digitally now because the requirements are expected to widen over time.

Which costs may landlords validly deduct from rental income?

Allowable costs can include letting agent charges, property repairs and maintenance, landlord insurance premiums, accountancy fees, ground rent and service charges, certain utility expenses during void periods and some legal fees. For most landlords, mortgage interest relief is restricted to a twenty percent tax credit instead of being a full deduction. Consistent digital record-keeping throughout the year helps ensure all allowable expenses are captured and reported accurately.

Is an accountant necessary when using property finance software?

Many landlords with uncomplicated portfolios successfully handle their own tax responsibilities using capable software. Accountants are particularly valuable to landlords whose portfolios are becoming more complex, those considering incorporation, those managing capital gains tax on disposal or those seeking a professional review of their annual return. Keeping records tidy through the year with software such as Sage generally reduces the time an accountant spends on the affairs, which usually lowers their fees.

Should a rental portfolio be incorporated into a limited company?

For some landlords, especially those with larger portfolios or higher income, incorporation may offer tax benefits. However, the decision also involves substantial legal and financial issues, including the effect on existing mortgage terms and stamp duty on transfer. It is not inherently advantageous, so professional advice tailored to individual circumstances is required before taking action.

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

The key priority is adopting HMRC-recognised software and beginning to retain digital records for every item of rental income and expenditure now. Landlords who start before the deadline can establish the necessary routine and develop accurate records for quarterly submissions long before the obligation takes effect, rather than having to manage a rushed changeover.
