What this means
- Every $100 of monthly HOA dues costs you roughly $15,821 of mortgage buying power at 6.50%.
- Ask for the reserve study before you buy. An underfunded reserve almost always turns into a special assessment or a steep dues increase.
How the hoa cost calculation works
HOA dues are the most underestimated line in a condo or planned-community purchase. Unlike a mortgage payment they are not fixed, they do not build equity, and they rise faster than general inflation because they track insurance and construction costs.
They also directly reduce how much house you can buy. Lenders count HOA dues in your debt-to-income ratio exactly like a mortgage payment, so $400 a month in dues removes roughly $60,000-65,000 of loan capacity at typical rates.
Frequently asked questions
What is a special assessment?
A one-time charge levied on every owner when the association needs money the reserve fund does not have — typically for roofs, siding, elevators, or plumbing. They can range from a few hundred dollars to tens of thousands per unit.
How do I judge whether dues are reasonable?
Compare what they cover. Dues that include water, insurance on the structure, and a well-funded reserve can be cheaper than a lower fee that covers landscaping only and leaves you exposed to assessments.
