Specific Question about Equity Investing

[AJay Williams]

Hello BP, My Grandma owns a Southern California 5 acre ranch. It is in Menafeehas a double wide trailer she lives in, it has a studio rental on the property and two corrals, also two big storage sheds, (200sqft and 1000sqft). All of the above is in tremendous disrepair and the grounds are in a defunct state as well. My question is does it seem likely that if I invest my own money and labor would her increase in profit be enough for me to get a return on my investment? Would it be ethical to do this and expect a return when she sells her house?
