Write her a 50 year lease that terminates upon mutual agreement to cancel the lease or death of the lessee?

I did several deals in NY, and if I recall correctly, NY does not require disclosure of murder, death, or suicide at the property. 

While my state, CA, does not have this, several states allow an Affidavit of Heirship which, when recorded with a certified death certificate, may allow title to be passed the heir(s) then sold to you.

Prelim had her as successor, which is not correct, and we provided paperwork of other successor death and notarized affidavit stating my seller as sole trustee.

But I also spent about 3 months researching to death the real estate market there before I was ready. 

Yes death is a fact of life but it is a shocking, sometimes life changing event.

Maybe this thread will have an early death since to find cash flowing properties in CA is like a unicorn and folks will want to keep their investing areas secret.

If they don't want to spend too much money on a family trust, hopefully they have one already, California passed a law recently that makes it very simple to accomplish the "Family Trust" issue called the "Transfer on Death Deed." 

I analyzed to death the past 4 years but only took action (thanks to my coach) last year.

Ideally, if you can get your hands on divorce list, Affidavit of Death, Tax Delinquent, Probate, etc. and filter those for equity, you will do well.To be honest, once you have a good list it is more important to send something than try to find the perfect mail piece.
