Does anyone have any suggestions or referrals?

I am also open to suggestion with an efficient way to find the most accurate comps 

So, I willing to read your thoughts, suggestions and advices.

There is a term for this that I am avoiding using, lest some unscrupulous tenant do an internet search and find a thread like this.I had this happen on two different buildings we bought because the previous owner did what you are suggesting . 

although they both are interdependent.The best way to understand costs is to get a Floor plan drawn and get quotes from at least 3 people in the area who have done ADU'sIt's always a good idea to involves a professional right from the start, especially someone who is experienced as they will suggest techniques that could bring value and save money in the long run.

It looks like the Tax Lien holder who filed for foreclosure, is asking the court to vacate the sale because I didn't pay within the 30days... anyone have any suggestions?
