please keep in mind that the following information if coming from a guy who is married to a woman who likes decorating and rearranging all the time.

They can give you an idea of what things you should pack, (family pictures, unique art, etc), and whether you can rearrange your furniture for the most welcoming presence or hire them to bring in staging furniture. 

We currently have a house we are doing this same thing to where the windows are in a master bath (after we rearrange walls).

Yes, you could rearrange the formula they way you did and it makes mathematical sense, but I think it messes with the psychology.  

I need to do some schedule rearranging to be able to make their meetings.

I don't know if that makes sense but I called the realtor and said well if we keep going along with this we need to re arrange the contract so the names are Tenant 1 and Tenant 3 but he says we don't need to do this.

There is an open basement below, and I am already redoing the supply lines in the basement so a little re-arranging isn't a big deal.Also this used to be a split dining room and kitchen, but I took out half of the wall splitting them, so there has to be some sort of eat in area or counter to eat at.

I have a couple low income places and it does take me "aback" when I walk in ... it takes some "re arranging" of gray matter to ignore!!

Then if you are moving walls to re-arrange the space you looking at structural engineering cost that could be  $1-$4k. 

Going with them will probably be the least expensive.If you're rearranging the LLC, make your parents minority owners, but use a figure that's less than 25% so they won't have to provide previous tax returns.
