Cash Flow Killers: 5 Maintenance Mistakes Multifamily Owners Make

Maintenance plays a huge role in protecting your bottom line as a multifamily property owner. In Seattle, where weather and wear can take a toll on buildings, the right approach to upkeep can make all the difference. 

Done well, maintenance preserves property value, keeps tenants happy, and reduces unexpected costs. Done poorly, it can quietly chip away at your net operating income (NOI).

This guide highlights five common maintenance mistakes that lead to higher multifamily maintenance costs in Seattle. Whether you're new to investing or already managing a portfolio, these tips will help you avoid costly oversights and protect your cash flow.

Mistake #1: Skipping Preventive Maintenance

Preventive maintenance may feel optional when everything seems to be working fine. However, skipping it is one of the biggest threats to long-term property performance.

Deferred maintenance often leads to surprise breakdowns, emergency repair costs, and frustrated tenants. Something as small as a clogged gutter or unchecked HVAC filter can cause bigger issues down the road.

Some common oversights include:

• Skipping seasonal HVAC inspections and filter replacements
• Forgetting to clean out gutters before winter rains
• Overlooking plumbing inspections for slow leaks
• Ignoring roof damage until it leads to interior water damage

These problems might not seem urgent until they snowball into major rental property repairs.

What you can do: Create a seasonal inspection/maintenance calendar that includes reminders for all critical systems. Regular checkups may feel like an added chore, but they’ll save money, prevent larger issues, and extend the life of your property’s key components.

Mistake #2: Working Without a Capital Improvement Plan

Many owners plan reactively. They fix things only when something breaks. That approach may seem cost-effective in the short term, but it often leads to large, sudden expenses that eat into your profits.

Not planning for expenses like roof replacements, HVAC upgrades, and siding repairs can lead to:

• Emergency financing or high-interest loans
• Last-minute vendor scrambling
• Disruption to tenants and lease renewals

The fix: Build a rolling 3–5 year capital improvement plan. It doesn’t have to be complex. 

Start by identifying:

• The age and condition of major systems
• Anticipated replacement timelines
• Estimated costs per year

This plan should include both capital expenditures (CapEx) and regular maintenance budgets. A proactive roadmap gives you time to save, phase projects out, and reduce risk.

Mistake #3: Choosing the Cheapest Vendor Every Time

Cost control is important. However, always going with the lowest bid can cost more in the long run. Unqualified or underpriced vendors may deliver subpar work. 

That often leads to:

• Rework and repeat calls
• Extended timelines
• Tenant complaints
• Compliance issues with Seattle building codes

In worst-case scenarios, hiring unlicensed or uninsured contractors could expose you to legal risk.

A smarter approach is to vet your vendors carefully. Look beyond price to evaluate:

• Experience and references
• Licensing and insurance
• Familiarity with local compliance standards
• Responsiveness and professionalism

At RPA, we only work with trusted vendors who understand the nuances of Seattle’s multifamily housing needs. That ensures our owners get quality service that holds up over time.

Mistake #4: Failing to Track and Analyze Maintenance Costs

If you don’t know what you’re spending (or where), you can’t improve your cost structure. Without clear records, it’s easy to lose money to:

• Redundant repairs
• Repeat service calls
• Overpriced materials
• Unnecessary upgrades

You may also miss out on patterns that could help you spot larger problems, like recurring issues with a specific unit or system.

Simple solutions: Use property management software or digital tools to log:

• Work orders
• Material and labor costs
• Vendor history
• Time to completion

Analyzing this data over time helps you budget better and identify opportunities to reduce property maintenance expenses.

If you work with RPA, we do this for you. Our systems make it easy to stay informed about your maintenance spend and how it affects your ROI.

Mistake #5: Neglecting Tenant Communication During Repairs

Even when the maintenance work is necessary, poor communication can create frustration. That frustration can lead to negative reviews, increased turnover, and damage to your reputation.

Tenants want to know what’s going on, to feel heard, and to be kept in the loop if repairs are going to affect their comfort or convenience.

When communication breaks down, tenants often assume the worst: that no one is managing the situation, that their concerns aren’t being addressed, or that their lease doesn’t matter.

Some simple ways to improve communication include:

• Notifying tenants well in advance of any repairs or service calls
• Providing realistic timelines
• Giving status updates if delays occur
• Following up to ensure satisfaction

Clear, respectful communication protects trust, and trust helps you retain quality tenants for longer.

Bonus Tip: Seattle-Specific Maintenance Challenges

Seattle’s unique climate brings additional wear and tear to multifamily buildings. Damp winters, salt air, and rapid temperature changes all play a role in building deterioration.

Some local issues to plan for include:

• Moisture intrusion and mold risk
• HVAC strain from cold, damp conditions
• Tree root intrusion in older plumbing systems
• Paint and siding wear from coastal rain

These issues impact aesthetics and can cause health problems and structural damage if not addressed.

Include weather-related items in your annual maintenance plan. If you’re not sure what to look for, RPA’s team of local experts can help you identify common red flags and create a preventive plan that fits your property.
