what's the Mechanical Rough Inspection signed offA duct blaster test?  

Hey @Sam Spina there are multiple forums and a step by step guide posted here on Bigger Pockets.  

It sounds like the seller has heard too many stories about homes getting multiple offers and selling higher than listing price.

This is an unstable person....multiple people have said they don’t feel “safe” around her...I understand about holding them accountable, but I also have actual fears that they know where I live.  

Just need to know if it’s bad business when getting multiple quotes?

If you ever decide to get a manager you will be able to afford it better with multiple close properties too.

I am working with general contractor who has concluded it will need to be demolished.In addition, we have tested the home for lead paint, and it’s positive.

Even though in some places one organization collects taxes for multiple taxing jurisdictions....for example the county may collect for, the county, the city, the school district, the hospital district, the community college district, the water supply, the noxious weed control district, etc, the individual entities may have lists too they would give you.   

There are multiple ones and they're nice and streamlined with you getting the signed certification letter via email within 24 hours "if you qualify".

If you can't test it, assume it doesn't work and budget to replace it.
