It always becomes a very difficult thing if you harm family members with an investment.

If they are disruptive, do harm or go against my reasonable rules, I can also evict them.  

You'll inherit the lease as is.There's no harm in asking them to sign your lease and they might say yes.

Maybe it's the optimist in me, or my faith knowing that God has plans to prosper me and not harm me that make me think I should over-extend myself rather than play it safe saving for a rainy day.  

There's no harm in making an offer.  

A buyer that might be harmed by buying a property at foreclosure sale where there is an active bankruptcy simple gets their money back.

I think it's key to also have a conversation with anyone in your family who may take it badly to let them know it's not personal, that you do value the personal relationship and are not trying to harm it, and to discuss with them any issues they may have.  

I wouldn't buy something this skinny in a C area unless I knew it was going to undergo some gentrification next week.No harm in offering what works, though.  

I am not impressed by these kinds of "headlines" because they don't do the average investor any good and could actually do harm.  

However, I don't see any harm in starting one right away so long as the expenses aren't prohibitive (like California's $800 annual franchise fee).
