we live in a house in a similar situation. our house is on the side of a lane, and when it rains heavily we have a small river running down the lane. The house is 100 years old so whoever put the house and lane there knew how to funnel the water away from house so we never have any issue. House never at risk of flooding either. During heavy rain we had a small wall at the back collapse as the earth pushed it a bit.
it might be handy for you to drive up if there's any heavy rain, and also call in and ask the neighbours. we got all the info about our house from them.
