I need to show the inside of the house to potential buyers, but she is not working with me, to put the dog up when I give her a 24 notice of entrance. 

We live upstairs and will rent out the basement which has a separate entrance.

The entrances aren't an issue with this property, we are working on financing for this specific situation, and we are checking with zoning to make sure the conversion is doable.

You will also need an electrical permit to have service restored to the building and may have to upgrade the entrance (we just upgraded to 400amp).

The Attic however, is illegally constructed and entrance is from the 2nd floor.

This is the "how".3 - Your REI Plan - This is based on reverse engineering from your financial goals (payoff debt and required monthly income), back to where you are now following (in reverse) a series of steps whereby each step when moving forward is executed because the exit from the previous step was based on what the entrance of the following step required. 

This might be a guard or gate at the entrance and exit.2.

Separate entrances?

Our exit cap rate (conservatively) was written at a 7.5% after a five year hold, with an entrance cap rate of 6.82%, and we still came out with almost 25% IRR after return of lender required reserves in year 1-2.
