WHAT SHOULD I DO W MY 80-100K???

[Miles Presha]

Recently re-fi'd to pay off tax debt. Going to walk w an extra 80K from the refi.  We are not sure whether or not to invest in some turnkeys, or  do some remodeling to our house - which could entail the cost of us having to move out during construction.  We area family of four living in a small 2 br house.  My oldest son is prob going to college in fall 2022.  I don't want that 80k just sitting in the bank so we are open to some professional advice.  What do you guys think?
