Typically, I believe if she didn’t actually adopt you that that the property, as per state inheritance laws, would go to her siblings, if she has no other children, and no spouse.  

@Susan O.It could be done, but the transfer in the father's share of ownership would be considered a gift and he would have to pay taxes on the gift.Also, non-married people buying a property together like a father/daughter would lose the capital gains exemption.This is to prevent people from adding their children to dodge estate taxes.

I've seen a couple of properties in Springfield especially with a sign from the county, something along the lines of "this property is an environmental hazard due to lead, unsafe for human occupancy, especially for children under the age of 6 and pregnant women..."

We could be risking not having ownership of the house in the future but she also has 2 children with me so I would have her keep the multi if we split up anyways...... is this a bad idea?

Not get rich quick schemes.I have young children and a job i got let go from a while back.

I would unload, and a lot of people do.I personally feel I would be setting a piss poor example of fiscal economy for my children. 

For instance, so far from a school, close to children that are not of his bloodline, etc.

I'm 27 years old with a wife and three children and I am looking to invest in real estate within the next year.

I have been married and divorced twice now and I have 2 beautiful children Brooklyn (13 years old) and Boston (10).  

Just because someone dies it does not mean their property passes down to their children.
