House with sump pump in an area not a lot of house has one

[Arif Bhuiyan]

I'm looking at a house that has past history of flooding the basement. Owner had fixed the damage in 2014 and installed sump pump with lifetime warranty. No issues since then other than pump got activated a few times every year. Pump is being checked up every year and has a generator too. What could be potential issues down the line if I buy the house. Only a few houses in the neighborhood has water issues. What kind of cap-ex I should keep in my long-term budget for any potential water issues? Property is in Greensboro, NC and I live out-of-state. Thanks so much!
