What Experienced Investors Regret Not Doing Early (3)

Key Takeaways

  1. Establish Proper Business Structures: Set up your rental property as a formal business, such as an LLC, and implement financial and legal systems to protect assets and maximize tax benefits.

  2. Conduct Thorough Tenant Screening: Use a comprehensive process to vet potential tenants, including background and credit checks, to avoid costly issues with nonpayment or property damage.

  3. Implement Proactive Maintenance: Schedule regular inspections and address maintenance issues early to reduce repair costs and keep tenants satisfied.



Being a landlord and real estate investor comes with a steep learning curve. Early on, you’re often forced to make decisions quickly without the benefit of experience. 

In that environment, mistakes are almost inevitable, and some of them can quietly erode your returns or stall your growth as an investor.

However, the biggest challenge for new landlords isn’t that rental property investing is unusually difficult. It’s that many investors try to solve every problem on their own. 

They overlook the fact that nearly every issue they encounter has already been faced and solved by experienced investors before them.

The real disadvantage, then, is failing to learn from those who have already navigated the path. When new investors don’t tap into proven strategies and hard-earned lessons, they end up repeating costly mistakes that could have been avoided.

The good news is that this doesn’t have to be your experience. Instead of learning everything the hard way, you can accelerate your success by learning from seasoned investors and applying their insights early.

In this guide from KRS Property Management, we’ll cover the top things experienced property investors say they regret not doing sooner so you can avoid those mistakes and build a stronger, more profitable investment portfolio from the start.

9 Things Successful Property Investors Wish They Did Sooner

By understanding what seasoned investors wish they had done sooner, you can avoid common pitfalls and build a stronger foundation for long-term success.

Here are 9 things investors regret not doing sooner:

1. View the Rental As a Real Business

For lots of successful landlords, property investing began as a side hustle. So, they did not see the need for a proper business structure or systems - financial, legal, etc. - for their rental. 

This mistake impaired their ability to protect their assets, avoid personal liability and maximize tax returns. Smart property investors know the value of creating the right ownership structures, such as an LLC, for their investment properties.

2. Create Accurate Rental Cash Flow Projections

Learning how to run the numbers on a prospective property investment is the foundational knowhow that all new property investors need. 

By understanding the right metrics to look at when buying a rental, investors can avoid buying a problem that masquerades as an asset. Many of the issues that newbie landlords later face with their rental properties can be attributed to a failure to forecast cash flow accurately.

3. Use a Thorough, Well-Written Lease Agreement

The lease agreement is a landlord’s first line of defense against legal troubles with the tenants in their property. By explaining what they can and cannot do, the lease ensures that tenants have the right expectations when moving into the property.

In the absence of a detailed lease document there will be confusion about the terms of the contract. If tenants don’t know the lease terms, landlords cannot enforce them.

4. Understand Property and Tax Laws

Landlord-tenant relationships are one of the most regulated in business. Also, there are entire bodies of local and state regulations that affect the operations and profitability of a rental property, such as zoning laws, building codes, sustainability and safety standards. 

Learning how these regulations work will help you avoid problems that can derail your profits. At the same time, it is important to master property tax laws if you want to maximize your returns.

5. Use a Comprehensive Tenant Screening Process

It is a mistake to lease your rental property without doing proper background checks on potential renters. By not paying the rent on time or at all, damaging your property and making other tenants’ lives difficult, one wrong tenant can severely hurt your entire operations. 

It is fine to outsource tenant screening to third parties but you are ultimately responsible for the outcomes because you alone will bear the cost of any mistakes.

6. Implement a Proactive Maintenance Strategy

Maintenance is one of the most critical aspects of property management. Most new landlords don’t have control of maintenance and repairs in their rentals because they wait until problems happen before they act.

The most effective way to handle maintenance in your rental property is to have periodic inspections that let you detect problems early and fix them at a minimal cost. Include a clause on seasonal inspections of all rental units in the lease agreement.

7. Prioritize Tenant Retention

It costs you less money to get an old tenant to renew their lease than it costs to find a new tenant. Tenant retention should occupy a higher rung than property marketing on the ladder of your priorities for the rental. 

To get tenants to renew their lease fix the common problems that tenants give as their reason for moving out of a rented home; poor maintenance, inadequate communication and an unfriendly landlord.

8. Understand and Apply Leverage the Right Way

Leverage will let you grow your portfolio significantly in a relatively short period of time. But a major mistake to avoid is trying to grow without first laying a solid foundation. 

This can lead to overleveraging, often resulting in a string of foreclosures if just one of your properties fails. 

With tools like HELOC and cash-out refinancing you can scale rapidly but balance this by understanding the importance of positive cash flow, substantial cash reserves and maintaining a healthy LTV ratio.

9. Prioritize Tenant Needs and Satisfaction

Keeping your tenants happy is not one of the things you must do to ensure the success of your rental property, it is the main thing. Good tenants are the lifeblood of a rental property. 

Treat your tenants well and they will reward you by becoming partners in the long-term success of your property. Rental properties where the tenants are happy usually have lower overall costs.
