5 Costly Accounting Mistakes in Rental & Leasing—and How Outsourcing Can Save You
January 22, 2026

Managing rental properties and leasing agreements is no small feat. Between tenant payments, maintenance costs, and compliance requirements, even minor accounting mistakes can lead to major financial consequences. Unfortunately, these errors are more common than you think—and they can cost property managers thousands in lost revenue, penalties, and inefficiencies.


Here are five common accounting mistakes rental and leasing companies make—and why outsourcing your accounting could be the smartest move for your business.




1. Mismanaging Security Deposits

Security deposits are subject to strict state regulations. They must be properly recorded, held in separate accounts, and returned within legal timeframes. Misallocating these funds or failing to track them accurately can result in legal penalties, tenant disputes, and reputational damage.

Example: A property manager accidentally uses a tenant’s security deposit for operating expenses. When the tenant moves out, the funds aren’t available—leading to legal action and fines.



2. Inaccurate Rent Tracking

Late payments, partial payments, and rent increases can easily cause errors in your books. Missing even one entry can throw off cash flow and make financial reporting unreliable. This often leads to incorrect budgeting and missed opportunities for growth.

Impact: Poor rent tracking can result in underreported income, making your financial statements inaccurate and potentially causing tax issues.



3. Overlooking Maintenance Expense Allocation

Property maintenance costs often get lumped together or misclassified. This can distort your profit margins and lead to incorrect tax deductions. For multi-unit properties, failing to allocate expenses properly can make it impossible to assess which units are profitable.



4. Failure to Reconcile Escrow and Operating Accounts

Rental businesses often manage multiple accounts for deposits, operating expenses, and reserves. Skipping reconciliations can allow discrepancies—or even fraud—to go unnoticed. Regular reconciliation is essential for catching errors before they spiral out of control.



5. Ignoring Compliance and Tax Rules

Rental income is subject to specific tax regulations, and mistakes in reporting can trigger audits or fines. Many companies also fail to properly account for depreciation on rental properties, missing out on significant tax benefits.



Why Outsourcing Is the Solution

Outsourcing your accounting to professionals who specialize in property management offers key advantages:

  • Industry Expertise: Outsourced teams understand rental-specific regulations and best practices.
  • Improved Accuracy: Reduce costly errors in rent tracking, deposits, and expense allocation.
  • Cost Savings: Avoid hiring full-time staff and reduce overhead.
  • Scalability: Easily handle growth as you add more properties.
  • Peace of Mind: Stay compliant and focus on tenant satisfaction instead of spreadsheets.



Bottom Line

Simple accounting mistakes in rental and leasing operations can cost thousands in lost revenue, penalties, and inefficiencies. Outsourcing ensures accuracy, compliance, and financial clarity—so you can focus on growing your portfolio.

SX Business Services Employee Spotlight: Jillian Palmieri, Property Accounting

By Lindsay Van Kauwenberg • April 17, 2025
SX was fortunate to welcome Jillian as a staff accountant in December of 2023, she was quickly and deservedly promoted to the position of Property Accountant a year later. She is a graduate of Suffolk University with a Bachelor of Science in Business Administration – with an accounting major and business management minor. Her father has been a business owner for 43 years and motivated her to garner the minor in business management to someday follow in his footsteps. Growing up in West Bridgewater, MA, she claims her summers were the best part of living there and enjoyed each season at the beach tanning away. She has two older siblings, one brother and one sister whom she is very close to. Her family had a black labrador for over 13 years and they miss her dearly. Someday she wishes to be home more to have the flexibility to adopt at least one dog again. She is looking forward to the opportunity to travel and has never really left the United States. Her family went to Niagara Falls on the Canada side when she was two… that counts right!!? A short list of dream locales to visit include Italy, Greece, Dubai, Hawaii, and any other tropical islands. Jillian – ‘In her own words’: Have you learned anything new as an adult that you didn’t experience as a child? I recently tried skiing for the first time, and I absolutely loved it. I gave my retired gymnast self-credit as it was easy to learn. I enjoy being active. If you could have any other job, what would it be? My dream job would be to own a busy coffee shop or café since my two prior years working at Starbucks gained me a coffee addiction. I would also like to open a business for mind/body health – such as a trampoline park to help people suffering from fibromyalgia/ being a fitness instructor/ and potentially help people further with their health through supplementation/diet. What do you like most about your job, and/or working for SX? I enjoy accounting especially ever since I got to SX – I have noticed great vibes since coming here, and everyone is super helpful. We really make a great team.
