I've hit some resistance finding the right team members as far as contractors, lenders, and home inspectors go.

My significant other is pretty resistant to 'downgrading' to another duplex/multi-unit for 12 months, which makes things a little more complex...

When you take out full height walls you reduce the structure's resistance to wind and earthquake forces. 

Some must have heat packs for supplemental resistance heat....  

Should also add- if tenant has resisted there for one year or longer and reason is not provided on request to vacate, the notice to vacate is voided and not legitimate

There's no central heat, only resistance baseboard, so you're going to have a hard time keeping renters with how high the utilities will be.https://www.zillow.com/homedet... 5 trailer trailer park.

Are you specifically talking about a primary resistance or investment property?

Sellers / owners are resistant of course to what they don't understand , especially during a seller's market. 

But, it's not waterproof, not even very water resistant.

I have been working with them so long I can navigate some of the resistance they can put up for fixing things as well.
