Getting home insurance . Age of house unsure.

Hello everyone , looking to get some advice . I'm moving into an older property in cambridge. The realtor docs had an approx age of 55-99 years .

My realtor and I have tried to look for exact age. Called the city they said they don't know the exact date but it is approx 1920. I was suggested to put age as 85 yr old. My question is would it be a problem if I put the age as 85, would it be a problem for future claims .

The house itself has been renovated and doesn't have any knob and tube wiring or lead plumbing . Roof , furnace ac etc all new .
