"I am looking at a couple of places that if I can fix up, we can make some money on....basically buy and flip idea..."
What about trying to get her to feel like part of the decision & using just a slight word change:
"What do you think about the idea of buying a place as an investment to fix up and flip & make some money on. It will give me a fun project to work on and a better place to stay while I am continueing to give you the space & time you need. What are your thoughts on that? Would you like to look at the 2 places I found?"
