Yes, depending on the condition of the house, and how temperamental it is. I was lucky with my last house, in 5 years of ownership only spent $6000, I took care of the lawn on my own. Roof was changed a year before I bought it so never gave me an issue and was under warranty. Water heater was a rental and was taken care by the company I was paying $20/month. After I sold the house, furnace gave up a week before the closing date so I got it fixed for $500. There was a water issue in the basement which cost $5000 to fix, but it still didn't blow the budget.

Just a datapoint, but sometimes $2500/year is a reasonable budget.
