Seemingly an obvious tool, yet most landlords throw it together carelessly. Leave out a single cost line and you lose a good slice of your real annual profit. And with long-term rental yields in big cities being modest, every amount you fail to account for stings. Seriously. Plenty of investors enter the rent and the utilities, and that&#8217;s it - end of report. The problem is that this isn&#8217;t even half the picture. Below you&#8217;ll find the specific items that regularly go missing from these accounts, and how to track them systematically every month.<\/p>\n\n\n\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_89 ez-toc-wrap-center counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">Spis tre\u015bci<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/tenanto.pl\/en\/monthly-rental-report-overlooked-costs\/#Operating_Costs_That_Vanish_from_Reports\" >Operating Costs That Vanish from Reports<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/tenanto.pl\/en\/monthly-rental-report-overlooked-costs\/#Utility_Billing_%E2%80%93_Where_the_Real_Amounts_Get_Lost\" >Utility Billing &#8211; Where the Real Amounts Get Lost<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/tenanto.pl\/en\/monthly-rental-report-overlooked-costs\/#Depreciation_of_Furnishings_and_the_Cost_of_Refreshing_the_Unit\" >Depreciation of Furnishings and the Cost of Refreshing the Unit<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/tenanto.pl\/en\/monthly-rental-report-overlooked-costs\/#Vacancy_Periods_and_the_Cost_of_Tenant_Turnover\" >Vacancy Periods and the Cost of Tenant Turnover<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/tenanto.pl\/en\/monthly-rental-report-overlooked-costs\/#Tax_and_Formal_Obligations_Omitted_from_the_Accounts\" >Tax and Formal Obligations Omitted from the Accounts<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-6\" href=\"https:\/\/tenanto.pl\/en\/monthly-rental-report-overlooked-costs\/#How_to_Build_a_Complete_Monthly_Report_%E2%80%93_A_Practical_Template\" >How to Build a Complete Monthly Report &#8211; A Practical Template<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-7\" href=\"https:\/\/tenanto.pl\/en\/monthly-rental-report-overlooked-costs\/#What_a_complete_monthly_rental_report_includes\" >What a complete monthly rental report includes<\/a><\/li><\/ul><\/nav><\/div>\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Operating_Costs_That_Vanish_from_Reports\"><\/span>Operating Costs That Vanish from Reports<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Most owners of investment properties enter the management fee into the report and stop there. But the real cost of maintaining a unit is a far longer list - and every item weighs on the budget on a regular basis. Don&#8217;t record them? Then the return you&#8217;ve calculated is pure fiction.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The cost items most often left out of monthly reports:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The housing community&#8217;s renovation fund<\/li>\n<li>Property insurance - building and liability policies<\/li>\n<li>Property tax<\/li>\n<li>Charges for managing and administering the housing community<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The renovation fund is a quiet trap, especially in new-build developments. For the first years of a building&#8217;s life, contributions for this purpose are either not collected at all or are symbolic. And then - bang. The rates go up, and owners who never accounted for this item suddenly have a hole in their budget. Liability and building insurance? Those are separate policies that almost nobody adds to the monthly statement. And their annual cost, spread across twelve months, is a fixed expense that ought to sit there.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Utility Billing - Where the Real Amounts Get Lost<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A classic. You set the tenant a flat-rate for utilities based on &#8220;roughly what it should come to.&#8221; Meanwhile, actual consumption shifts with the seasons and depends on the habits of the particular tenant. Underpayments accumulate over months, and at the end of the billing period you pay out of your own pocket. The differences can be surprising.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Each of the items below needs to be tracked separately:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Electricity and gas - the option to shorten billing periods<\/li>\n<li>Water and sewage - billed quarterly or annually<\/li>\n<li>Heating - annual settlement depending on the housing community<\/li>\n<li>Waste collection - rate set by the municipality<\/li>\n<\/ul>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>With room-by-room rentals, <a href=\"https:\/\/tenanto.pl\/en\/settling-utilities-rental-step-by-step-guide\/\">settling utilities<\/a> can be tricky. Because tenants may change fairly quickly, it&#8217;s best to ask suppliers to shorten the billing periods. This isn&#8217;t a problem for electricity and gas, but for water, sewage or heating, shortening the billing period generally won&#8217;t be possible.<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">What should you do in practice? Take meter readings every month and compare them against the flat-rate being charged. That way you make corrections as you go, instead of discovering at the end of the year that you&#8217;re several hundred zloty short. Simple, but it works.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Depreciation_of_Furnishings_and_the_Cost_of_Refreshing_the_Unit\"><\/span>Depreciation of Furnishings and the Cost of Refreshing the Unit<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A rental flat needs refreshing. Regularly. And that expense should sit in the report every month - not land on your head as a one-off blow. Because when you suddenly have to repaint the whole flat and replace the washing machine, you lose several months&#8217; worth of profit at once. Setting aside small amounts each month solves this problem. But who actually does it? Exactly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Typical replacement and renewal cycles for furnishings:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Repainting walls - every few years, depending on how intensively the unit is used<\/li>\n<li>Replacing appliances (washing machine, fridge, dishwasher) - when they reach the end of their life, so set the reserve aside from the day of purchase<\/li>\n<li>Repairs to plumbing and electrical systems - ongoing, with a reserve for emergency call-outs<\/li>\n<li>Replacing furniture and finishing elements - every few years<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Tip:<\/strong> Add up the value of all the flat&#8217;s furnishings, divide it by the expected useful life in months, and you have a monthly depreciation rate. You enter it as a fixed cost. For example - furnishings worth 20,000 z\u0142, assuming a 6-year service life, comes to about 278 z\u0142 a month. That 278 z\u0142 should appear in the statement as a depreciation reserve. No discussion.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Vacancy_Periods_and_the_Cost_of_Tenant_Turnover\"><\/span>Vacancy Periods and the Cost of Tenant Turnover<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The time between tenants costs money. And almost nobody factors it into the average monthly result. Every day without a tenant means not just lost income - you also have to cover administrative charges and utilities in standby mode. These amounts reduce the annual return in proportion to how long the unit stands empty.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">On top of that comes the cost of acquiring a new tenant. Listings on property portals, a possible agent&#8217;s commission, the time spent vetting candidates - all of it has measurable value. Change tenants once a year? Then you incur these costs regularly. But in the report? Silence.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Room-by-room rental as a strategy for minimising vacancy? It often works. In this model it&#8217;s rare for all the rooms to stand empty at once. The flat generates income even with partial turnover. The yield can be higher, though it takes more administrative effort. It&#8217;s worth being honest about that.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Tax_and_Formal_Obligations_Omitted_from_the_Accounts\"><\/span>Tax and Formal Obligations Omitted from the Accounts<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The flat-rate tax on rental income. You pay it as a matter of obligation, but do you enter it into your monthly report? Most owners treat it as &#8220;something separate&#8221; and only account for it in their tax return. Yet this amount directly reduces your net profit and should be visible every month. Otherwise you&#8217;re only deceiving yourself.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Since 28 April 2023 you have to provide the tenant with an energy performance certificate (EPC) before signing the agreement. This also applies to renting out single rooms. No document? You risk a fine. The cost of obtaining it - put it in the accounts and have peace of mind.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Formal items to include in the report:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Flat-rate tax on rental income<\/li>\n<li>The cost of obtaining the energy performance certificate<\/li>\n<li>Any adaptation to KSeF requirements (e-invoices)<\/li>\n<li>Fees for accounting services or settlement software<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Potential tax changes in 2026 could shake up the way rental income is accounted for. Keeping track of the regulations and factoring them into the report as you go lets you avoid nasty surprises.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to Build a Complete Monthly Report - A Practical Template<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A good report has five sections. First - income (rent, surcharges). Second - fixed costs: administrative charges, property tax, insurance, the renovation fund. Third - variable costs: utilities, minor repairs, expenses for acquiring a tenant. Fourth - a reserve for depreciating furnishings and future refreshing of the unit. Fifth - the net result. Simple? Simple. But complete.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Automation helps enormously. A SaaS <a href=\"https:\/\/tenanto.pl\/en\/9-problems-a-single-rental-management-system-will-solve\/\">rental management system<\/a> gathers rent, deposits and documents in one place, and you can export income and occupancy reports from the app to PDF or XLSX. You still add utility costs and other expenses yourself, but the report has something to start from. In the <a href=\"https:\/\/tenanto.pl\/en\/pricing\/\">Tenanto price list<\/a> the first unit costs 0 z\u0142 and each additional one 15 z\u0142 net a month. It pays for itself quickly, because you have control over your cash flow and nothing slips past you.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Comparing reports month on month catches anomalies - a sudden jump in utility costs, a missing depreciation reserve, an omitted flat-rate tax. Tracking trends gives you a basis for reacting quickly to drops in profitability. And that is precisely the difference between an investor who manages and one who guesses.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_a_complete_monthly_rental_report_includes\"><\/span>What a complete monthly rental report includes<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A complete monthly report isn&#8217;t just rent and utilities. It&#8217;s the depreciation of furnishings, reserves for vacancies, tax burdens, the cost of tenant turnover. With a modest yield, every omitted item eats into your real profit. Simplified statements? That&#8217;s a systematic overstatement of your return.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One tool, systematic reporting - and the risk of overlooking costs drops to a minimum. Regular analysis lets you catch the items that lower your profitability and make decisions based on data, not on gut feeling. Implementing this template is a one-off effort, but you reap the benefits of precise financial control throughout the entire life of the investment. There&#8217;s no point putting it off.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Most landlords leave key costs out of their rental reports.
