For some perspective, I have owned 4 plex's in Lansing, IL,  a south suburb of Chicago that borders Indiana.  

Total cost for that has been less than $30 (yellow paper pads for yellow letters, pens to handwrite them, envelopes, and stamps, as well as a one month subscription to Intelius.com to find out weather these people are deceased or alive and if they have email addresses and phone numbers incase I get the courage to cold call). 2.

In May 2020, I was declared deceased by Wells Fargo.

@Minu LalDo a search of the forums here and, more importantly, find yourself an account experienced with cross-border business.LLCs do not exist in Canada, so you would not be setting one up here.  

Even then I recommend buying in state or bordering state that is within 2 hours away (so you could drive there if you had to)  I have a portfolio of rentals in Dayton OH and have had mixed results. 

***An old real estate investor friend of mine (now deceased) purposely drove a 97' Ford Ranger to pickup rent, to meet contractors, etc which helped disguise his true net worth/lifestyle (over 12million).

However, each person's situation is different so best to consult with an experienced cross border tax and/or legal specialist.  

I just need some help with mineral rights and also the property is in a deceased persons name.

the main difference is hiring a contractor from afar can be something that is very hard to do bordering on a nightmare scenario...

Within this file you will find the Decease, the address of the property, the attorney info, PR (executor or administrator) Phone number and address (PR's are who you will market to for the property).
