What to do with my $$$?

[Enrique Rivera Jr]

My family and I recently had an apartment fire which started in our apartment in a Co-op building which we owned. Thankfully everyone was evacuated safely with no injuries. Now we pretty much lost everything and insurance paid up to $60K for our personal belongings and dwelling in the meantime while our apartment gets renovated by the buildings insurance company. Out of the $60K we currently have about $40K left over after paying for rent in another place where we staying in the meantime. Now my wife and I agreed after 9 years of living in the Co-op we should try listing it for sale after the renovations are completed I believe we can sell the Co-op for around $100K. My question is should I invest into a duplex and live in one unit and rent out the other? Or where should I invest the $$$ into? In total we would have $140K to invest in anything we want. Thanks in advance!
