Don’t spend time talking to them about the mechanics of what they do - that’s available anywhere.

Do you know bike mechanics?

The mechanics of the deal are not too complicated, although as others have noted you can't advertise the property and then exclude people based on protected class including gender and family status....at least not legally. 

Is it the end of the world if you don’t pull them if it is truly cosmetic, non-mechanical/non-structural?

I do concur with Chad that you might want to start closer to home to learn the mechanics of the business.  

Them being the 3 mechanicals (HVAC, ELECTRICAL, PLUMBING) and ROOF.

Just bought a long term rental in Florence, SC with a non-working pool (ripped liner & old mechanics).

With a savvy realtor and attorney, you can put forth a competitive offer that still protects you by waving the contingency with limited exceptions to mechanical, structural, environmental, and health and safety issues.

@Tim Bishop  also I assume that is mechanical harvest  feller bunchers ?

However, it's important to note that these mechanisms may not cover all regions.As developers, we collaborate closely with leading real estate consultancy, valuation experts, and research companies.
