You can walk away especially with 300+k. I just did but for a lot less. That was always in my plan tho. I bought in to get out of my dead end job. Ran a profitable business for 8 years and sold. It did take 2.5 years to sell (also very niche) but some of that was the pandemic. I plan on getting a certification and starting my next journey. The money from the sale and my wife’s support does help with the transition. You can plan and make a change. Good luck
There is an app that you can rent storage space to your neighbors. I forget the name
