Or 5s for what should be a solid 6 submarket.So far being patient....

You just need to be patient and work with a good agent!

She's patient and has been amazing with explaining things to me. 

Just omit any mention of that point, but you can still mention that the seller would save $ vs listing on the market because you would be dealing direct and can essentially bypass agents (if they desire, or say you have no problem if they want to be represented for safety, they key is making them comfortable).

While our deck and railings are secure, I constantly fear someone might do something foolish -- or worse, a child might do something naively -- and fall.What is the best way to help communicate safety to guests, and what are steps I should take to minimize liability should something happen?

Any lawsuit on safety, fire can cause you arm and a leg. 

The Anti-Eviction Act, N.J.S.A. 2A:18-61.1, and the Summary Dispossession Act, N.J.S.A. 2A:18- 53, provide the following grounds for the removal of tenants that may constitute emergent circumstances justifying an LT trial:• Disorderly tenant (N.J.S.A. 2A:18-53(c) or 2A:18-61.1(b));• Willful or gross negligent damage to premises (N.J.S.A. 2A:18-53(c) or2A:18-61.1(c));• Abating housing or health code violations (landlord seeks to permanently board up or demolish premises because cited by authorities/inspectors for substantial health and safety of tenants) (N.J.S.A. 2A:18-61.1(g));• Occupancy as consideration of employment (N.J.S.A. 2A:18-61.1(m));• Offenses under comprehensive drug act (N.J.S.A. 2A:18-61.1(n));• Assaults or threats against landlord or certain other persons ((N.J.S.A. 2A:18-61.1(o));• Eviction for civil violations (tenant found by preponderance of evidence that theft of property, assault, terroristic threats against landlord or member of their family, employee of landlord’s, etc.)

The only way to evict at the moment is if the tenant is destroying the property or there is an imminent safety risk. 

Is it customary to install a dryer with no air vent (couldn't there be safety issues involved)?

They only use the back exit.This is obviously a safety issue.
