Here is a report from FEMA and the US Fire Administration that details the fire/explosion danger which you can cite to support your PM. https://www.usfa.fema.gov/downloads/pdf/publications/electronic_cigarettes.pdf

I know to find out the value of other properties with a agent but do not know how to find out repair estimates.

He only gave you an estimate, not a fixed price bid. 

Based on your posting the damage seems to be extensive, especially since it’s affecting the structure of the home such as a floor beam, sill plate and subfloors.It appears there is active termites as well as a beetle issue and both must be resolved before repairs can de done.You didn’t mention home value, just purchase price so it’s difficult to say what to do from this point.At a minimum, I would have the termites and beetles dealt with and get a bond from the termite company to cover the first year for more treatment.Also, have a licensed contractor give you a repair estimate.

Admittedly, I'm pretty new at searching for general property details in any shape or form, so it would not surprise me if a search like this is super obvious and I can slap myself in the head. 

Hi Terri,Can you PM me more details on your duplex.

I'm struggling to estimate the increase or decrease in property taxes each year.

Feel free to share any other provider details that you have worked with to get Trust Deed.

accommodate a buyer's request for detailed rental and financial history, when selling only a small segment of your overall portfolio?

@Mickey Bradshaw  there really is quite a lot of detail that goes along with a being a JV partner,  much more than is suggested by gurus.
