Grab your local newspaper and in the classified section go to legal notices and the heading will be titled Notice of Probate, Petition of Probate, Administration of Probate.Good luck.... 

However, once you have lived in that property for 2 out of the 5 year period prior to the day you sell you can take the first $250K ($500K if married) in profit tax free  using the sec 121 primary residence exclusion.

From what I have heard in our local news paper, is that the rental market as of right now is in a 10 year low.

... or, can she give you an exclusive right to "manage" them for her such that you pay her property-related expenses and keep any profit above that?

But this investor done it in NY and I read a newspaper article some years back where someone convicted or murder, sentenced to 30 years, NNN his expensive residential property so he still has it when he is released.Briefly a long term NNN lease is one that exceeds 30 years, and as much as 99 with option to renew.

Section 121 (c)(2)(B) indicates you would qualify for at least a ratio of the exclusion because you were forced to relocate due to a change in employment location. 

I'm very new to real-estate investing and I have a question about Real-Estate Agents and "Exclusive Right to Work-With Agreements."

Run "we buy houses" ads locally in newspapers to build that list and add more hot leads.

If I find a place I may have you sign an agreement for that property but not an exclusive to cover all places.
