During the annual re inspection I was told  that the attic needs a handrail ( I didn't realize it never had one).

Is there any specific type of inspection which could confirm there is no more issue with the house regarding the water damage?

By the time you are called to do an appraisal or inspection the property has already been bought.

Rental Inspections required? 

He put in jumpers instead of fixing the problem, so I then had to pay someone else, that I COULD CONTROL, to come and fix the system legally...so it could pass inspection and not start a fire.Now I am very firm that I am the one paying for the work and if I do not agree to the work I do not pay and no one speaks for me. 

Pay yourself.Summing these up and adding to your already-listed expenses:Maintenance - $270CapEx - $270Vacancies (5%) - $135PM (8%) - $216Expenses you listed: $650Total percentage expenses per month - $891Total Expenses per Month: $1,541So your Income minus Expenses:$2700 - $1541 = $1159 income per monthThe last thing to be added in as expenses, and is dependent on your area: Inspections and Licensing.

To negotiate, I used the inspection report as a basis for what needed to be fixed.

Inspections aren't always necessary and the cost for them isn't that much in the grand scheme of things. 

I do want the purchase contingent on an inspection and seller's ability to providing a clear, unencumbered, marketable title. 

(I will use it sporadically the rest of the time).I have asked my agent to get a letter from HOA in reference to the timing of the increase.I am “reportedly” buying it from an elderly couple ,the house inspection was fine but still does not feel right..
