Original deed is in name of parents who are both deceased. Male passed May of 97' Female passed Oct 97'...had three siblings: son passed Aug 89' youngest daughter passed Apr 2011...eldest daughter would be sole distributee decendent thru NYS succession law...Eldest daughter resides in PA and has agreed to a one third partnership with common law husband of youngest sister He is the primary residence since 2011 with a tenant occupant..Another third agreed to to her nephew, the only son of her sister who is the voluntary administrator of things of lesser value on the property and whose name appears on home insurance, property taxes, water sewer, etc....So the question becomes , if deed were ultimately placed in my name and we used the FMV at the time of death of youngest sister (396K), along with 50K of sweat equity placed in the property by primary resident since 2011, how would this 33 and 1/3 factor into Capital Gains on the one third partner and would the other two partners be subject to any severe taxes on money gained from a future sale. THANKS for your TIME and ATTENTION
