Can anyone recommend a structural engineer/contractor that won't charge an arm and a leg to analyze?

Roof will need replacement in the near future.2) EXTERIOR: - (including siding, drive/walk): No problems found.

I am replacing a few floor decking sheets, replacing the entire bathroom in one tore walls out put in new studs, tub, toilet, etc. 

Have to replace it on Monday.

I'm looking at replacing the gas heater with a newer Rinnai heater for the safety concern of using half a dozen space heaters.

I work as a technician at Safelite replacing/repairing auto glass and my wife works as a CNA. 

But a bit of advice if I may, nothing replaces the personal attention that’s needed to gain the confidence of someone to sign your offer letter.

Can I use that as a bargaining chip on my inspection contingency by telling the seller: "Look, I will be ok with x that needs to be replaced based on the inspection but because of the radon mitigation I want $x amount off the property" or would that be illegal/breach of contract because I technically waived that particular contingency?

If you are realistic with both, the 1031 rules give you plenty of time to locate the replacement property.

I once replaced a smooth top electric stove with a coil top.
