Rental property expenses can use up the gap between your rent and mortgage payment. Before you take money out, plan for months without rent, bills, repairs and work the home will need later. Track loan payments apart from the cost of running the home. Your tax return needs its own figures. The budget below shows how $3,000 in monthly rent can leave just $200 for the owner.

Build the budget from the property you own
Start with bills, service contracts and records of the home’s condition. If you own the rental, review a full year of spending and older records of major work. If you plan to buy, get insurance quotes, an inspection report, HOA records and a tax estimate for that home. A seller’s low spending does not tell you whether the roof or heating system needs work.
Separate purchase and make-ready cash from the ongoing budget. Closing costs, work to get the home ready and rent lost before you can lease it need funds up front. If you plan to change the home, ask the local building and planning staff about its proposed use, permits and review process. Get a written work schedule before you set a rent start date.
Recurring costs that outlast the tenancy
Property taxes, insurance and HOA dues
Use the property’s actual tax bill and ask the assessor about a pending purchase or construction project. In California, a change in ownership generally triggers reassessment to current fair market value unless an exclusion applies. The Board of Equalization’s change-in-ownership guidance explains that rule.
California owners can also face supplemental tax bills. The Board’s supplemental-assessment guidance explains that qualifying ownership changes and completed new construction can produce bills in addition to the annual bill. Keep those one-time cash needs separate from the ongoing annual estimate.
Get an insurance quote that describes how you rent the home and what it has. Ask which risks the policy covers and what it leaves out. Check any loss-of-rent terms; do not assume they cover all time without rent. Use the new premium when the policy renews. Keep cash for the deductible, the amount you would pay toward a covered claim.
Read what HOA dues cover before you add more service costs. If those dues pay for shared lawn care, avoid counting the same work twice. Check notices of special assessments and planned projects as well as dues. A low monthly bill alone does not show what you may owe later.
Utilities, landscaping, pests and pools
List the utility bills you pay while the home is leased and while it is empty. Water for the yard, shared lighting, trash and empty-unit service can remain owner costs. Use bills and the lease to work out who pays. Check local rules before changing those terms.
Landscaping needs a budget for each season. Keep mowing or gardening apart from tree work, sprinkler repairs and new plants. For pest control, list planned service and the cost of treating an active problem on their own lines. Our yearly maintenance checklist can help you turn the faults you find into planned work.
A pool adds more than a cleaning visit. Price service, chemicals, water and power, then put aging pumps and other parts on the list for future work. If a service quote includes chemicals, count them there once. Use local quotes for your pool to set the budget.
Management and owner administration
Enter management costs from the proposed agreement. Check how the monthly fee works and whether you pay extra to lease the home, renew a lease or arrange repairs and inspections. Ask what fees apply while the home is empty. Compare the cost for a full year using your planned rent and leasing costs.
If you manage the home yourself, allow for your time. You may still pay for bookkeeping, software or help with tax and legal work. Utopia’s property management services page explains the services; request a quote for your rental to put a fee into your budget. The example below assumes an owner-managed home and includes no management fee.
Vacancy, leasing and turnover need separate lines
Vacancy reduces income. Cleaning, photography, listing costs and screening services are spending. Budget for both. Do not assume screening costs will be recovered from applicants; verify the rules for the property’s jurisdiction before charging a fee.
For example, two empty months at $3,000 a month mean $6,000 less rent. Any cleaning or repairs during those months are extra costs. A national vacancy rate cannot tell you when your home will next sit empty. Use its past leases, the time needed for work and nearby listings to choose how much rent to set aside.
Unpaid rent needs its own review. A rent ledger shows amounts charged and received. In your forecast, reduce the rent you expect to collect by that shortfall. Do not also subtract the same unpaid rent as a cash expense.
Fund repairs and replacements without counting them twice
Your repair budget pays for work this year. A service call or small plumbing repair goes in that bucket. Saving for a new roof or heating system needs a longer plan. List the home’s main parts, their condition, when you think each will need to be replaced, current quotes and cash you have saved.
Choose one method for each bucket. You might start by setting aside a share of rent for repairs, then use a dollar figure based on your records. A share of the home’s value is another rough planning choice. These choices are not verified 2026 cost benchmarks. Do not add either on top of a budget that funds the same work.
Here is an example of a capital reserve, the cash you save for major work in the future. Suppose you need $6,000 more for a roof in 60 months and $3,600 more for equipment in 36 months. Save $100 a month for each, or $200 total. These are assumed targets, not price quotes or promised life spans. Revise the plan as quotes and condition change.
Keep cash for urgent costs alongside the plan. Test how long you could pay bills without rent and what a major fault could cost to choose a target. Build that cash balance and top it up when used. Once funded, do not subtract the full target again each year.
When a repair happens, record the bill against the repair budget. When you replace a major part, use its saved funds and record the work. The transfer to savings is not a second bill for that job. Count the vendor’s bill once when you work out the project’s total cost.
An illustrative annual cash-flow budget
This owner-managed home has no pool. All amounts below are assumed for this example. They are not 2026 market averages, Utopia fees or a forecast for your home. The vacancy allowance is a chosen 5% of scheduled rent. To get the monthly figures, divide the yearly amounts by 12. Real bills will not fall in equal monthly shares.
| Budget line | Annual amount | Monthly equivalent |
|---|---|---|
| Scheduled rent | $36,000 | $3,000 |
| Less vacancy and collection allowance | $1,800 | $150 |
| Expected rent collected | $34,200 | $2,850 |
| Property taxes | $3,600 | $300 |
| Insurance | $1,800 | $150 |
| HOA dues | $1,200 | $100 |
| Owner-paid utilities | $600 | $50 |
| Landscaping and scheduled pest service | $1,200 | $100 |
| Recurring operating costs subtotal | $8,400 | $700 |
| Routine repair spending allowance | $1,800 | $150 |
| Leasing and turnover spending allowance | $1,200 | $100 |
| Total operating spending | $11,400 | $950 |
| Net operating income before debt and capital savings | $22,800 | $1,900 |
| Less loan principal and interest payments | $18,000 | $1,500 |
| Cash flow before capital savings | $4,800 | $400 |
| Less transfer to future capital savings | $2,400 | $200 |
| Cash available to owner before income tax | $2,400 | $200 |
The subtotals are checkpoints, not additional expenses. Expected collections of $34,200 minus $11,400 in operating spending leave $22,800. Subtract $18,000 in loan payments and $2,400 in capital savings to leave $2,400. The loan line excludes tax and insurance escrow because those costs appear above.
This example starts with $6,000 saved for urgent costs, so there is no extra transfer to build that fund. If you start without that cash, saving it leaves less for you to take out. It also assumes you pay for no major project this year. Work next year would use saved cash. You would need new funds for any part those savings do not cover.
Test a worse year before you rely on the $200 monthly figure. One extra empty month reduces annual collections by $3,000. With the same planned spending and transfers, the $2,400 left for the owner becomes a $600 shortfall. Extra repairs would deepen that gap.
Use the rental property ROI calculator to test your own loan and cost figures. For a view of income before loan payments, use the cap rate calculator. Check how each tool treats reserves and change its preset values to match your home before you compare the results.
Tax deductions are a separate calculation
A cash-flow budget does not calculate taxable profit. IRS Topic 414 explains the cash method: count rent when you receive it and, as a general rule, claim eligible costs when paid. Moving money to your own reserve account is not payment of a repair expense. Cash-basis owners also cannot deduct rent they never collected.
IRS Publication 527, the 2025-return edition found when checked, lists common rental expenses such as insurance, management fees, repairs and mortgage interest. It says you cannot deduct loan principal as an expense. Keep the lender’s breakdown of interest and principal even though both parts use cash.
The IRS tangible-property guidance distinguishes repairs from capital improvements. It checks work against the relevant asset, called the unit of property. For a building, the structure and key systems get their own review. Betterments, restorations and adaptations to a new use are defined tax categories that generally require capitalization. This adds the cost to the asset’s tax basis instead of treating it as a current repair expense.
A contractor’s label of “repair” does not settle the treatment. Safe harbors and elections have conditions, so do not assume each replacement gets an immediate deduction.
Depreciation lets you recover property cost for tax purposes without a new cash payment that year. Personal use and rental-loss limits can also change your return. Keep bills, details of the work and the dates you first put assets into service for your tax preparer. The cited publication covers 2025 returns, not final 2026 filing instructions. Check the rules for the tax year you file.
Frequently asked questions
How much should I reserve for repairs?
Use the home’s condition, past repair bills and current quotes to set a repair budget. You can start by saving a share of rent, then use your own records to refine it. Save for major work in its own fund. Avoid adding more than one budget for the same job.
Should I count taxes and insurance twice if my lender escrows them?
No. Show taxes and insurance on their own budget lines, then put loan principal and interest in the loan line. If you track the full mortgage payment instead, split out the part held for taxes and insurance so you count those bills once.
Is money transferred to a repair reserve tax-deductible?
A transfer between your own accounts is not a paid repair expense. With the cash method, you can generally claim eligible costs when you pay them. Check the tax rules to decide whether the later work is a repair or a capital improvement.
