You could honestly go down 15% off of the ARV of a similarly valued piece of land in your area and what is the harm done?

Often if you have a valid reason for taking some action other than playing games, they'll likely buy it, depends on how good your initial reason was or is, especially if there is no harm and done well. :)

I do not know the legality behind not being able to change locks if the property has not been occupied, but do not see the harm in trying to secure your property in the meantime.  

Needless to say the insurance was not renewed at the end of the year.Insurance companies rarely if ever pay out like you would assume that they should, and often do more harm then good as the very long delays in repairs causes significant stress on your tenants and strains your relationship with them. 

What course of action would cause them the least amount of harm in the short/long term?

Unless the $50. is make-or-break then what's the harm?

You are liable for damages if that pet bites or harms someone on your property.

You have an obligation to prevent any further harm to your tenant, which might mean temporary housing, a complete lead test and depending on the results, professional remediation.Hopefully, your insurance will cover some of the costs, but even if it doesn't, you need to take this very seriously and act as quickly as possible.This link may help: https://www.nolo.com/legal-encyclopedia/lead-discl...

Lead safe implies there could still be lead paint, but it is encapsulated so the outer surface is not as harmful.

From the sound of it, title companies seem harmless and that they could not harm me but I still want to make sure I do the due diligence necessary.
