Or have a home inspector look at the home before doing any work to the house?

I would definitely try a walkthrough or even a video walkthrough with the inspector.

On the second , your contractor doesnt pull permits and you get busted by the inspector , a 4 month delay and fines .  

The inspector came back with like four pages of things wrong and 99% of it was really nit picky things or things he would have done differently than my builder did, not wrong, just his opinion. 

I'm looking for a property inspector in the Duluth/Superior (Minnesota / Wisconsin) area.

Pay to have professional inspectors, pluming, electrical, etc...

When can I have my inspector go in?

If anyone has any referrals for inspectors or insurance agent please send them my way! 

From what I can tell, you have the option of using them either as your home inspector or in addition to your inspector to verify the necessity of improvements for the 203k loan (you have to use one) - https://entp.hud.gov/idapp/html/f17cnsltdata.cfmFor regular 203k loans, there is a minimum of $5,000 in repairs to add to the mortgage of the house.

For me, as an investor and agent, I am always looking at what level of rehab will yield the most profit.A second frame of reference will come from your home inspector.
