The monthly cost of owning a Kirkland condo is not just the mortgage payment.

A complete calculation should include:

  1. Mortgage principal and interest
  2. Property taxes
  3. Condominium association dues
  4. HO-6 insurance
  5. Utilities not included in the dues
  6. Parking and storage charges
  7. Maintenance of systems and finishes inside the unit
  8. A personal reserve for special-assessment risk
  9. Any assessment or association-loan payment already attached to the unit

That distinction can materially change what a buyer can afford.

A condo with a lower purchase price can have a higher total monthly cost than a more expensive unit if it carries high dues, a large assessment payment, weak reserves, or unusually expensive insurance and utilities.

I have served as an HOA board member and treasurer through a major condominium recladding project and special assessment. I have also been preparing my own Kirkland condo for sale. That experience is why I separate the association’s current monthly charge from the owner’s broader financial exposure.

The ownership-cost model I use is:

Monthly housing cash flow = mortgage + property tax + HOA dues + insurance + utilities + in-unit maintenance + parking and storage + assessment obligations + personal risk reserve

This article is educational and is not lending, tax, insurance, legal, or investment advice. Every buyer should replace the illustrative inputs below with the property’s actual documents, lender quote, insurance quote, tax information, and expected ownership costs.

Start with the monthly cash-flow number

There are at least three different ways to describe the cost of a condo:

1. The listing payment

This is often a mortgage estimate based on an assumed price, down payment, and interest rate.

It may exclude:

This number is useful only as a starting point.

2. The total monthly cash-flow requirement

This is the amount that is likely to leave the owner’s bank account each month.

It includes principal repayment even though principal increases the owner’s equity. This is the number I would use to answer:

Can I comfortably carry this condo every month?

3. The economic cost of ownership

This is a more detailed investment calculation. It may separate:

That analysis can be useful, but it should not replace the basic cash-flow calculation. A buyer can have a favorable long-term economic model and still be unable to absorb a sudden assessment or increase in dues.

This article focuses primarily on the monthly cash-flow requirement.

1. Mortgage principal and interest

The mortgage calculation requires:

Do not use a generic online estimate when making an offer. Use a written lender scenario based on the actual property type, down payment, credit profile, occupancy, and loan program.

Condominium financing may also depend on the building. A lender may review matters such as:

The loan quote should therefore be treated as provisional until the lender has reviewed the condominium.

2. King County property taxes

Property taxes should be calculated from the property’s assessed value and applicable levy rate, not from a rough percentage copied from another property.

The King County Assessor provides the following basic formula:

Assessed value divided by 1,000 × levy rate = annual property tax

The levy rate depends on the property’s taxing district. The King County Assessor publishes levy rate reports and explains the calculation in its levies FAQ.

For a monthly ownership model:

Annual property tax ÷ 12 = estimated monthly property-tax cost

The purchase price and assessed value may not be identical. Use the property’s actual assessed value and levy information, then review the most recent tax statement for special charges, exemptions, or changes.

Do not assume the current tax bill will remain unchanged throughout ownership. Assessed values, voter-approved levies, taxing-district charges, and exemptions can change.

3. Condominium association dues

The monthly HOA dues are usually the most visible condominium-specific cost.

The amount alone does not tell you whether the dues are high, low, adequate, or inadequate.

You need to know what the dues cover.

Possible included expenses may include:

Two Kirkland condos with the same monthly dues may have very different economics if one includes water, sewer, garbage, heat, parking, and strong reserve contributions while the other does not.

Separate operating costs from reserve contributions

The association budget should show how much of the dues supports:

A low monthly fee can reflect efficient operations. It can also reflect underfunded reserves or delayed maintenance.

Washington reserve studies are intended to identify significant future maintenance, repair, and replacement costs and provide funding information. Under RCW 64.34.382, an older-act condominium reserve study addresses components such as roofing, painting, paving, decks, siding, plumbing, and windows when applicable. Under RCW 64.90.550, a WUCIOA reserve study must include qualifying reserve components, replacement-cost assumptions, remaining useful lives, reserve balances, funded percentage, recommended contributions, and long-term funding plans.

A buyer should compare the association’s actual reserve contribution with the contribution recommended by the reserve study.

4. Model the trajectory of HOA dues

I would not underwrite the condo by assuming today’s dues remain unchanged forever.

The purpose is not to predict an exact increase. It is to test whether the purchase still works if expenses rise.

The adjustable formula is:

Future monthly dues = current dues × (1 + assumed annual increase)^number of years

Illustrative and adjustable trajectory

The following figures are illustrative and adjustable. They are not Kirkland market data and are not a prediction for any association.

A buyer should create at least three scenarios:

The most useful assumption may come from the association’s own records. Review:

5. HO-6 insurance

The association’s master insurance policy does not replace the buyer’s need to obtain a unit-owner insurance quote.

The buyer should ask an insurance professional about:

The correct amount depends on the master policy and declaration.

A buyer should request:

A WUCIOA resale certificate must describe the association’s insurance and provide contact information for the association’s insurance broker or agent. It must also disclose the current budget, assessments, reserve-study status, anticipated major repair costs, and other financial information. RCW 64.34.425 requires similar core disclosures for condominiums currently governed by the older Condominium Act.

Do not use a generic national insurance estimate. Obtain a property-specific quote.

6. A personal special-assessment risk reserve

The association’s reserve fund and the buyer’s personal cash reserve are not the same thing.

The association reserve belongs to the association and is intended to fund common expenses.

A personal risk reserve belongs to the owner. It provides liquidity if:

I would not describe this personal reserve as a prediction that an assessment will occur. It is a stress-testing tool.

How to set the amount

There is no universal monthly number that fits every Kirkland condo.

The amount should depend on:

A newer or well-funded association may justify a smaller personal risk allocation.

A building with an outdated reserve study, major exterior work under investigation, or a recent depletion of reserves may justify a larger amount or a larger cash balance outside the monthly budget.

The resale certificate should disclose levied and unpaid special assessments, certain anticipated major repair costs, reserve-study status, financial statements, the operating budget, insurance, and other association obligations. Buyers should use that information to adjust the personal risk reserve rather than choosing a percentage blindly.

7. In-unit maintenance and replacements

Condo ownership reduces some exterior maintenance responsibility. It does not eliminate maintenance.

Depending on the declaration and unit boundaries, the owner may be responsible for items such as:

Responsibility for windows, doors, decks, balconies, pipes, and mechanical systems can vary by community.

Do not infer responsibility from physical location alone. Read:

The monthly maintenance reserve should reflect the systems serving the actual unit.

A condo with a newer interior may need less near-term maintenance, but the buyer should verify what was replaced, whether permits or HOA approval were required, and whether warranties transfer.

8. Parking and storage costs

A listing may advertise parking or storage without making the ownership and cost structure clear.

Confirm whether each space is:

Also ask about:

A $50 or $100 monthly charge may not change the purchase decision by itself, but it should be included in the calculation.

9. Utilities not included in the dues

Buyers should obtain a written list of what the association pays.

Potential owner-paid utilities include:

A building may include water and garbage while leaving electricity, gas, and internet to the owner.

Another building may use common boilers or shared hot-water systems that are funded through dues.

Do not assume that services included for the seller will remain included at the same cost. Review the current budget and recent utility expenses.

For a more accurate calculation, request the seller’s actual utility history when available, then adjust for household size and usage.

10. Existing special-assessment or loan payments

A levied assessment may be:

The listing may describe an assessment as "paid" even though the association continues to carry project debt or owners continue paying through higher dues.

Before calculating the monthly cost, confirm:

The resale certificate is a starting point, not the only source. Compare it with the unit ledger, assessment resolution, association-loan documents, meeting minutes, construction budget, and purchase agreement.

Complete illustrative monthly ownership example

Every input in this example is illustrative and adjustable.

The numbers are not Kirkland market data, are not a mortgage quote, are not an insurance quote, and do not describe a specific condominium.

Illustrative purchase and financing inputs

| Input | Illustrative and adjustable amount |

| ------------------------------ | ---------------------------------: |

| Purchase price | $650,000 |

| Down payment | 20 percent, or $130,000 |

| Mortgage amount | $520,000 |

| Mortgage term | 30 years |

| Mortgage interest rate | 6.50 percent |

| Monthly principal and interest | $3,286.75 |

The illustrative mortgage payment uses a standard fixed-payment calculation. Taxes, insurance, dues, and other expenses are not included in the $3,286.75.

Illustrative monthly property inputs

| Utilities not included in dues | $180.00 | Illustrative household estimate |

| Total monthly cash-flow requirement | $5,183.42 | Sum of all illustrative inputs |

The illustrative property-tax percentage is used only to demonstrate the calculation. It is not represented as the current Kirkland levy rate. Replace it with the assessed value and levy rate for the specific parcel using King County Assessor information.

What the basic mortgage estimate misses

In this illustrative example:

That difference is not a minor adjustment. It is more than 57 percent of the illustrative principal-and-interest payment.

This is why I would not evaluate a condo from the mortgage payment alone.

Stress test 1: HOA dues increase

Assume the illustrative HOA dues increase immediately by 15 percent.

Every figure remains illustrative and adjustable.

The purchase may still be affordable.

The question is whether the buyer’s budget had at least $97.50 of real monthly capacity or whether the original calculation already used every available dollar.

A buyer should also ask why the increase occurred.

An increase used to strengthen reserve contributions may improve the association’s long-term position.

An increase caused by a temporary insurance spike, utility increase, loan payment, or emergency deficit may require a different interpretation.

Stress test 2: Special assessment payment

Assume the association later levies an illustrative $48,000 assessment against the unit.

Assume, only for this illustration, that the association allows the owner to pay it over eight years with no interest.

Every figure remains illustrative and adjustable.

This simplified example excludes interest, financing fees, late charges, and early-payment discounts.

If an association loan carries interest, the actual monthly amount should be calculated using:

The buyer should use the actual assessment resolution and loan documents.

Stress test 3: The personal reserve is not enough by itself

In the illustrative base model, the buyer saves $250 per month toward special-assessment risk.

After three years, excluding investment returns, the buyer would have:

That is useful liquidity, but it would not fully fund the illustrative $48,000 assessment.

The purpose of the personal monthly reserve is not to guarantee that every assessment can be paid in cash. It creates options:

A buyer may also need a separate emergency fund and accessible savings beyond the monthly ownership model.

My ownership-cost model

When comparing Kirkland or Juanita condos, I would use this sequence.

Step 1: Calculate current mandatory cash flow

Include:

This is the minimum monthly obligation.

Step 2: Add owner-controlled reserves

Add monthly amounts for:

These are not monthly bills, but excluding them makes the property appear cheaper than it is.

Step 3: Review association financial risk

Analyze:

Step 4: Model future monthly costs

At minimum, test:

Step 5: Compare buildings on total cost

Do not compare only:

Compare the full monthly cost and the quality of the financial position behind that cost.

A condo with $800 monthly dues and strong reserves may be financially preferable to a condo with $500 dues and a major unfunded exterior project.

The documents determine whether the difference is justified.

Documents needed for an accurate calculation

Before finalizing the cost model, request:

  1. Current resale certificate
  2. Current association budget
  3. Most recent financial statements
  4. Current reserve study
  5. Unit assessment ledger
  6. Special-assessment resolutions
  7. Association-loan documents
  8. At least 12 months of meeting minutes
  9. Insurance summary and deductibles
  10. Declaration and amendments
  11. Parking and storage documents
  12. Current property-tax statement
  13. Seller utility history, when available
  14. Unit-specific HO-6 quote
  15. Written lender estimate

Under RCW 64.90.640, a WUCIOA resale certificate includes assessments, certain major anticipated expenditures, reserve-study status, financial statements, the operating budget, insurance information, fees, and other association records. RCW 64.34.425 provides the resale-certificate framework for many condominiums currently governed by the older Condominium Act.

The model is only as reliable as the documents behind the inputs.

Common calculation mistakes

Treating HOA dues as the only condo-specific expense

Dues do not show the buyer’s full exposure to:

Assuming low dues are automatically better

Low dues may reflect low operating costs.

They may also reflect:

Counting the association reserve as personal savings

The association controls the association reserve.

The buyer cannot withdraw an individual share to replace an appliance, pay a personal deductible, or cover the buyer’s assessment installment.

Ignoring what dues include

A $750 monthly fee that includes water, sewer, garbage, heat, parking, and strong reserve funding may not be directly comparable with a $550 fee that excludes most of those costs.

Using the seller’s insurance premium

Insurance pricing is specific to the buyer, coverage, deductible, insurer, unit, and building.

Obtain a new quote.

Ignoring the future buyer

A condo may be affordable today but harder to resell if:

The buyer should model not only the cost of entering the property but the financial condition likely to exist when selling it.

Frequently asked questions

Are HOA dues included in a condo mortgage payment?

Usually not. A lender’s quoted principal-and-interest payment generally excludes HOA dues. A lender may collect property taxes and some insurance through escrow, but the buyer should confirm each payment component directly with the lender.

How should I estimate Kirkland condo property taxes?

Use the property’s assessed value and actual levy rate. King County’s formula is assessed value divided by 1,000, multiplied by the applicable levy rate. Divide the annual result by 12 for a monthly estimate.

How much should I save for a future special assessment?

There is no universal amount. The personal reserve should reflect the reserve study, building condition, upcoming projects, association debt, insurance exposure, and the buyer’s other liquid savings. It should not be based only on the monthly dues.

Are high HOA dues always a bad sign?

No. Higher dues may fund meaningful services and adequate reserves. Lower dues may be reasonable or may postpone future costs. Review the budget, reserve contributions, services, insurance, debt, and maintenance plan before comparing associations.

Should mortgage principal count as a monthly cost?

For cash-flow planning, yes. The full mortgage payment leaves the owner’s bank account each month. For a separate investment-return analysis, principal can be treated as equity accumulation rather than an expense.

Final perspective

The cost of owning a condo in Kirkland is not one number printed beside the listing price.

It is a system of connected obligations:

The correct calculation does not require predicting every future expense.

It requires making the known expenses complete, making uncertain expenses visible, and testing whether the buyer can remain comfortable when the optimistic assumptions do not hold.
