Condo vs House Cost Comparison

Comparing a condo to a house on sticker price alone tells you almost nothing. The condo is usually cheaper to buy and carries a fee that never goes away; the house has no fee and hands you the roof. This calculator lines up what each one costs you per month and adds it up over the years you expect to stay.

What it adds up, for each property: Monthly carrying cost = Mortgage P&I + HOA fee (condo) or maintenance (both) + Property tax + Insurance Total = Monthly carrying cost × 12 × years

What it deliberately leaves out, and why it matters. There is no appreciation and no equity here. That is not an oversight, it is the honest limit of a monthly-cost comparison: a $500,000 house costs more every month than a $350,000 condo largely because you are buying $150,000 more asset. If the calculator subtracted appreciation it would be guessing at two growth rates over a decade, and the answer would follow whichever guess you fed it. So read the result as “what leaves my bank account each month”, not “which one makes me richer”. Those are different questions, and only the first one has a reliable answer.

The mortgage assumes a 30-year term at the rate you enter, on both properties.

Key differences between property types:

Typical annual maintenance costs:

• Condo (inside only): 0.5–1% of unit value
• Single-family house: 1–2% of home value per year

A condo owner does still pay for maintenance, which is the part people forget. The HOA handles the roof, the siding and the parking lot. It does not replace your water heater, your dishwasher, your flooring or the air handler in your own unit. Budget something for it. The default of 0.5% is the low end of the range above, on the reasoning that the expensive exterior items are already covered.

Worked example over 10 years. A $350,000 condo with a $450 HOA fee against a $500,000 house, both at 6.5% with 20% down, 1.2% property tax, house maintenance at 1.5% and condo at 0.5%:

The condo costs $127,017.80 less over the decade. It is also $150,000 less house. Whether that is a saving or a smaller purchase depends entirely on whether you wanted the space.

The fee is the part that behaves differently. Your mortgage payment is fixed for thirty years. An HOA fee is not: it is reset by a board every year, it rises with the cost of everything the association buys, and it can be joined by a special assessment for a roof or a garage deck that the reserve study underfunded. Ask for the last three years of budgets and the current reserve study before you sign anything. A low fee on a building with no reserves is a bill you have not received yet.

Other factors to weigh:

• Condo lifestyle: shared amenities (pool, gym), less privacy, noise through shared walls
• House lifestyle: yard space, more privacy, and every repair lands on you
• Condo mortgages can carry a rate premium, and a lender will refuse the loan outright if the building fails warrantability tests: too many rentals, one owner holding too many units, pending litigation, or reserves under 10% of the annual budget
