I really appreciate you taking the time to put forth such a comprehensive response. 

After asking the tenant to put it back, no response from the tenant.

You should contact a property surveyor and have the property surveyed to verify the boundaries of the property.

Mike, thanks for the response.  

The ARV is pretty accurate....I haven't gone to see the property yet, just trying to decide if it has the potential to be worth it...Thank you John, happy to hear any other insight you can think of after these responses.

@dmitriy fomichenko    Thank you for your response.

Ive have horrible experiences (bank took months between updates even though we have a law that says they have to respond within 30 days, because if you demand a response, guess what it will be.) it took 10 months to get a final agreed upon price.

A trustees fiduciary responsibility is a very serious thing and if they don't live up to it they can be in huge trouble, or the trustee IS living up to it... quite hard to know without a copy of the trust and verifying the property is therein.If there is still a probate going for this same deceadents estate... after 10 years that would be quite extraordinary, I had one that will last even longer but it has exceedingly rare and complicated circumstances. 

It will get you a pretty good response rate.

I'm told that the process can take about 3 months and will require building plans and necessary surveys.
