Even if the new appraisal came in at the $94sqft number that would give me roughly an additional 30k of equity to potentially use for the next deal. 

This is NOT something you dabble in and in addition you will need specific intensive training for.People can often make the mistake of trying to dabble in a few things (grass is always greener,etc.)

Looking to get some quotes from local handiman/contractors to get this thing back into using as a comfortable addition to our modest house and possibly renting out as an Airbnb.Who's got recommendations/referrals in the greater Seattle area!?

The addendum states"Tenants hereby expressly and knowingly release, discharge, and hold harmless Landlord from any and all liabilities arising from any injury, harm, loss, or other events which may occur as a result from Landlord's dogs.

These are professionals with additional training and a stricter code of ethics.

There is an "insured" and an "additional insured", and someone mentioned that you can only name one of each on the policy for insurance company he use.

Live in one unit and rent the others, this would give you additional units without extra mortgages, and help scale your business quicker. 

Additionally, if you have other advice or suggestions, I'd welcome that as well. 

If your goal is to keep the existing renters and rent out individual rooms on AirBnb, then you would be required to follow some additional rules.   

There is the possibility of expansion as we are going to get about 15 additional Acres that have not been developed yet.
