Indeed a technician (a risk assessor or dust sampling technician, I assume... but anyone can do it) can swab a surface for hazard residue.

It also means we do not get stuck with the residual usage from the last partial billing period when the tenant moves out.There is administrative overhead to operate the programme and we levy a small administrative fee for the extra work to generate statements and send copies of the bills to tenants.As for maintenance and CAPEx, we normally budget 10% of effective gross revenue for maintenance and set-aside of 8-10%of retained earnings into our CAPEx fund.

As for the stock investors who spend little time studying, that is great for them, but have you ever considered that they could be outliers, lucky, and/or using the residual affects of years spent in the markets?

This is a residual presumptive test of either positive or negative does not give a level.

Residual Value?

The remaining “residual” cost is then assigned to the building itself.

I want my RE biz to be a blend of residual income with the bigger one-off commission chunks, so there's less of the feed and famine scenario! 

I've also wiped down all the surfaces in the house to get off any smoke residue.
