It's not only required, I found it to be extremely helpful and enjoyable. https://quizlet.com/175950706/flashcardsLet me know if you can't get into the cards but I don't think it should be an issue. https://quizlet.com/175950706/flashcardsLet me know if you have any issues getting into these I'm not sure if I need to give you permission or anything. 

You don't need permission to ask someone how much they make per month.

I gave permission to enter.

When I see a property that has those features I get permission from the listing agent and get it on my social media feed.

It is your property and they should not be making any changes to it without your permission. 

It is better that they called you to get permission.

@Diego MarambaI doubt any seller is going to give you permission to work on a property which you do not yet own.

Better yet upload it to your favorite cloud storage space and give them the permissions to view any time they want so you are not resending 

I have appraised many properties with illegal conversions, additions, etc..A typical example was when the garage was converted into a unit or additional living space, without permits or in an sfr zoned area which doesn't allow for ADUs. if it isn't a legal conversion or is not legally permissible per zoning, then most likely, it would be treated as an sfr with a "cost to cure" adjustment applied to convert it back to an sfr.

They don't have to give permission, you can enter at the time you said.
