They don't mind "rent to own" signs but their blood pressure explodes when they see "we buy houses".

Don't rent to "blood relative" family. 

The insulation tends to get thinner and thinner.

There is a thinner version, with shallower grooves which is made from OSB - that seems likelier to be what you might find on a mobile home..BTW:  be prepared to find that the apparent damage is just the 'tip of an iceberg'.  

After the meeting I needed the rest of the day to get my blood pressure back into its normally above average range and to replace my rage with run of the mill anger.

I have grown up doing every aspect of this industry from maintenance to management and feel Real Estate is in my blood.

Be careful this stuff gets in your blood :)What a great start to having your own business.
