The Biggest Mistakes New Landlords Make (and How to Avoid Them)

Are you a new landlord, trying to avoid the most common pitfalls and mistakes that are waiting to be made?

Here’s something you should know: even experienced landlords make mistakes. Owning a rental property is a constant learning process. 

Many first-time landlords underestimate how complex property management can be. From tenant screening and legal compliance to maintenance and financial planning, it’s easy to overlook details that can turn a promising investment into a major source of stress.

The good news is that you can avoid the most common pitfalls. We’re talking about them here, and sharing a few strategies for avoiding them. 

Quick Takeaways: Screen tenants thoroughly and set clear expectations. Budget for maintenance and vacancies from day one. Know your legal obligations and don’t forget to plan for taxes. Price your rental property accurately. Communicate well and invest in good tenant relationships. Get good insurance and work with property management experts.

Tenant Screening Mistakes

One of the most common and expensive mistakes new landlords make is rushing to fill a vacancy without properly screening tenants. California laws require you to accept the first person who applies and meets your qualifications. So, you have to set some pretty high standards and you need to be consistent with them. 

Skipping or rushing the screening process can lead to late payments, property damage, evictions, or even legal disputes. An unreliable tenant can cost you thousands of dollars in unpaid rent, legal fees, and repairs. Worse, an eviction can take months and require you to carry the cost of the mortgage and expenses in the meantime.

Avoid potentially placing an unqualified tenant by putting together a smart screening strategy that includes: 

• A complete rental application, including employment, income, rental history, and references.
• Background and credit checks (with proper authorization).
• Verify employment and income to ensure the tenant can afford the rent.
• Check landlord references to spot red flags like prior evictions or unpaid rent.

Setting clear tenant selection criteria that comply with fair housing laws is the best first step.

Underestimating Maintenance Costs

Many first-time landlords make the mistake of thinking their property will only need occasional fixes. But even well-maintained properties require regular upkeep, and surprise expenses always come up. If you don’t budget for maintenance, you may not have funds available when problems arise. Deferred maintenance can also make issues worse and more expensive to fix later.

Avoid this mistake with a strong maintenance budget. We like setting aside around 10 percent of what you collect in rent. When you can set up a reserve fund like this, you’ll be ready to pay for emergencies such as HVAC repairs, roof leaks, or water damage. We also recommend scheduling preventive maintenance, such as HVAC services, gutter cleaning, and plumbing inspections. Don’t forget the landscaping and the pest control. 

Respond quickly to repair requests to keep tenants happy and protect your investment. Good maintenance isn’t just about fixing problems. It’s about preserving your property’s value and keeping reliable tenants long-term.

Legal Mistakes Are Expensive Mistakes 

California is pretty detailed when it comes to landlord-tenant laws, and compliance can be tricky if you don’t fully understand the law. New landlords can often find themselves tripping over: 

• Rent control laws.
• Security deposit requirements, limits, and timelines.
• Habitability standards and enforcement.
• Fair housing laws.
• Just cause evictions. 
• Fees and notices.

The best way to protect yourself against making an expensive legal mistake is by understanding your requirements and responsibilities as a landlord, especially when it comes to tenant protections. You cannot go to an occupied property without a reason. You cannot refuse to renew a lease agreement without cause and, potentially, a relocation fee. You cannot refuse to allow a tenant to move in with an emotional support animal, even if you have a strict no-pets rule.

Get to know the laws. If that seems like too much, partner with a property manager who already knows the law and prioritizes compliance. 

Setting the Wrong Rent Price

Pricing a rental correctly is a delicate balance. A rent that is too high could lead to longer vacancies and a struggle to find qualified tenants willing to pay it. A rental price that’s too low only leaves money on the table, making it difficult to raise the rents to market levels later on.

Avoid overpricing by:

• Researching comparable rentals in your neighborhood to determine fair market value.
• Consider your property’s unique features and amenities when setting rent.
• Reviewing rent annually and adjust based on market trends and local regulations.

Online tools are a great starting point, but you need accurate and reliable data. We can provide insights that will help you price your property accurately and profitably. 

Neglecting Tenant Communication

Good communication is one of the most underrated skills in managing a rental property. New landlords often make the mistake of being unresponsive, unclear, or inconsistent with tenants, and that almost always leads to frustration, misunderstandings, and turnover.

Tenants who feel ignored may withhold rent, file complaints, or move out at the end of their lease. Poor communication can also make disputes harder to resolve.

Here’s how to avoid communication mistakes: 

• Respond promptly to messages, repair requests, and concerns.
• Use clear, written communication to document agreements and conversations.
• Establish preferred communication channels (e.g., email, property management platform).
• Treat tenants with respect and professionalism at all times.

Communication leads to positive tenant relationships, and those relationships can lead to long-term leases, fewer vacancies, and better property care.

Not Having a Plan for Vacancies

Vacancies are inevitable, even with great tenants. But too many landlords are caught off guard when a tenant gives notice, leading to lost rent and rushed decisions. Vacancies can be an expensive problem for rental property owners, so you have to know how to avoid them and manage them. 

Keep a vacancy reserve fund to cover expenses during turnover periods. When you do have a turnover, make sure your vendors are prepared to work quickly so you can re-rent the home in a reasonable amount of time.

Focus on tenant retention so that turnover is rare and vacancy is brief. Remember that well-maintained, fairly priced properties with strong marketing don’t stay vacant for long.

Doing Everything Yourself is a Mistake

When starting out, many landlords try to handle everything on their own. This is your investment and your project, of course you’ll want to be in control of the maintenance, marketing, screening, legal paperwork, and all the tenant communication. 

But that gets old quickly. Especially if there are conflicts and confusions. 

While DIY management can work for some, it often becomes overwhelming. Without the right experience, you may miss legal requirements, mismanage maintenance, or burn out trying to juggle everything. This can also slow down growth if you plan to acquire more properties.

Consider hiring a property manager, especially if you’re planning to grow a portfolio. You’ll need a strong team to ensure you’re successful. Partner with vendors, attorneys, brokers, insurance agents, tax experts, and CPAs. 

If you leave the day-to-day management to professionals, you can focus on your high-level investment strategy. Your time is valuable. Investing in the right support can increase efficiency, profitability, and peace of mind.

Rental Property Insurance

We have seen new landlords make the mistake of thinking they can keep their standard homeowner’s insurance policy when they’re renting out a home. But, that’s not enough. Without the right insurance, you may face huge out-of-pocket expenses for property damage, liability claims, or loss of rental income. Get landlord insurance (also called a dwelling policy) to cover the structure, liability, and loss of rent. Require renters insurance so tenants can protect their belongings and reduce your liability.

Review your policy annually to ensure adequate coverage.

Ignoring Tenant Retention

We mentioned the importance of retention when we were talking about vacancy. Let’s dig a little deeper. 

Acquiring new tenants is expensive. Between marketing, cleaning, repairs, and lost rent during vacancies, you’re spending a lot of money when a tenant moves out. High turnover eats into profits and can lead to inconsistent cash flow. Good tenants who stay long-term help stabilize your investment.

Here’s how to prioritize retention and avoid turnover:

• Respond promptly to maintenance requests.
• Keep the property well maintained and updated.
• Be fair, respectful, and professional in all interactions.
• Consider small incentives for lease renewals, like upgrades or rent discounts.

A happy tenant is your best asset. Long-term tenants mean stronger cash flow.

Failing to Plan for Taxes

Rental income comes with both tax responsibilities and opportunities. Many new landlords fail to plan ahead, resulting in tax surprises or missed deductions. Yes, you have to claim your rental income on your taxes. But, you can also access a number of deductions and tax advantages. 

Without proper tax planning, you may owe more than expected or fail to take advantage of legal write-offs. We recommend you work with a professional tax expert. Track all rental income and expenses throughout the year and make sure you’re leveraging all of the deductions available to you, including those for mortgage interest, property taxes, repairs, depreciation, and management fees.
