In my opinion it is to intrusive and leaves people upset that you are bothering them at home.

On one hand, this is intrusive, but if they want your place and have been honest this shouldn't be a problem and they well know that their credit is going to be a barrier to many rentals they might pursue.

This isn't standard, so I'm wondering if there was some indication that there was water intrusion or a previous mold problem?

Step one: stop the water intrusion, whether that involves the roof, proper drainage away from foundation, leaks from windows, etc.Step two: remediate the mold, be careful and worth having evaluated by the pros, might not be a DYI depending on type, extent.

I get called out on water intrusion issues all the time when the crews have exhausted their options.

Foremost is mainly concerned with the shell of the home including the roof, being secured and not exposed to weather and or intrusion.

However the least intrusive way of handling it would be to simply make the contract assignable.  

We get nothing like the clay you guys fight .. ours is water intrusion.. for all the great reasons you state thats why I suggested he stay put and let his mentors lead him through this... 7k homes in CA is Major development and would be in most markets so obvioulsy those are Big buck boys.. stick to them

For bigger jobs, anything involving manly tools, like saws or tile cutters, any work that could cause water intrusion, ask your laborer to carry general liability insurance to cover him/herself and his/her work.  

It is best to create AND FOCUS your exhibits on “unseen” items… items discovered only because you actually completed “intrusive inspections” THEN, bring in the “seen” items to make the exhibit longer… if you have time…If you don’t have any unseen items, then you have to work with the best repairs you can find…  and also remember … Your opening paragraph should go into an official state addendum form provided to you by your agent… either you send an email to the agent to tell them the words … (best when the agent is working with you)or you get the blank state addendum form, and put the words in (required when the agent is NOT working with you) .. and your opening paragraph could be something like this:"Due to hazardous Conditions, Code Violations, Unpermitted and Out of Code Improvement, and Structural Defects & Systemic Defects sited in the exhibits below with a total Cost to Cure of $32,700, the Purchase price of the property will be $38,000; the Cost to Cure is evidenced by “Exhibit #5 - Certified, Inspection #0826157538” and “Exhibit #6 - Contractor’ s bids, License #_____________”, and in the following exhibits [found in the attached file name {Forensic Cost to Cure Disclosures Addendum and Exhibits-7538SMarshfield}, attached hereto and an integral part thereof; namely:Exhibit #1 – Code Violation / Hazardous condition - Main service line to Meter & Inferior electrical panel - Cost to Cure : $1,500Exhibit #2 – Structural Defect – Rotting and Failing Fascia & Soffit around 90% of structure – Cost to Cure : $2,700Exhibit #3 – Code Violation / Hazardous condition – Cost to Cure : $1,500Exhibit #4 – Structural Defect – Cost to Cure : UnknownExhibit #5 - Certified, Inspection #0826157538 – 35 pages Exhibit #6 - Contractor’ s bids, License #_____________” – 4 pages,and again ..
