Getting Inspection on home before putting in a bid

[Demon S Rogers]

Hey everybody simple question what do think about having an home inspector come out and performing an inspection on a house before you put a bid/offer on it. I've only seen the inside but realtor told me it needs new sub floors I want to get inspector to come in an confirm them have a contractor come look and give me an estimate. Do you think this is acceptable or normal to do before I put in a bid or not. I understand the market in the US and don't think this place is going anywhere anytime soon and if somebody does snatch it up I'll be fine.... thank you all. If anyone could give valuable input that would be great thanks.
