Calculating ROI for Rental Properties in New Hampshire: Key Expenses to Include

When evaluating rental properties in New Hampshire, understanding how to accurately calculate your return on investment (ROI) is crucial to making sound financial decisions. ROI helps you assess whether a property is likely to generate desirable profits over time relative to the capital invested. A thorough ROI calculation incorporates all relevant expenses associated with property ownership and management to give you a realistic picture of cash flow and profitability.

Below, we detail the essential expense categories that New Hampshire rental property investors should include when calculating ROI. By considering these costs, you can effectively analyze properties across different markets within New Hampshire—from the Lakes Region to the Greater Manchester area—and make informed investment choices.

Key Expenses to Include in ROI Calculations

1. Mortgage Payments

  • Principal and Interest: This is often the largest recurring expense for investors using financing. New Hampshire lenders typically offer various mortgage terms, so factor in your monthly principal and interest payments accurately.
  • Mortgage Insurance (if applicable): If your down payment is less than 20%, mortgage insurance premiums may add to your costs.

2. Property Taxes

  • New Hampshire’s property tax rates vary by municipality, often based on assessed property values. Taxes can be significant, especially in more urban areas.
  • Confirm the current property tax rates with local tax assessors when budgeting.
  • Include annual property taxes prorated to a monthly expense in ROI.

3. Homeowners Insurance

  • New Hampshire’s weather patterns, including winter storms and potential flooding in some areas, can influence insurance premiums.
  • Obtain a detailed quote for landlord insurance, which may differ from standard homeowners coverage.
  • Factor this premium as a monthly expense.

4. Property Management Fees

  • If you hire a professional property management company in New Hampshire, typical fees range between 8% and 12% of monthly rent.
  • Consider this cost especially if investing long-distance or managing multiple units.

5. Maintenance and Repairs

  • New Hampshire’s seasonal climate means landlords should budget for seasonal maintenance like snow removal or heating system checks before winter.
  • Allocate a monthly reserve, typically 5% to 10% of rent, to cover ongoing repairs and upkeep.
  • Include both minor repairs and major capital expenditures such as roof replacement, HVAC systems, or structural work over time.

6. Utilities (If Paid by Landlord)

  • If utilities such as water, sewer, trash collection, or electricity are included in rent or partially paid by you, account for these expenses.
  • Utility rates in New Hampshire can vary, so check with local providers for estimates.

7. Vacancy Allowance

  • To accommodate inevitable vacancy periods between tenants, include a vacancy rate—often 5% to 10% of gross rental income—to avoid overestimating cash flow.
  • Vacancy rates in New Hampshire may vary by location; for example, student-heavy towns might experience seasonal vacancies.

8. Legal and Accounting Fees

  • Legal fees may be necessary for lease agreements or eviction processes.
  • Annual accounting services for tax filing and bookkeeping should also be budgeted.
  • While these may not be monthly expenses, allocate an average monthly amount to capture these costs annually.

9. HOA Fees (If Applicable)

  • Some New Hampshire rental properties, especially condominiums or planned developments, charge HOA fees.
  • Include these fees as recurring expenses if applicable.

10. Advertising and Tenant Screening

  • Expense related to marketing the property and screening tenant applications.
  • Allocate a portion monthly if advertising regularly, or factor in per turnover cost amortized monthly.
