What the hell is wrong with you?
You have no customers and an idea you can't explain. What makes you think you can build this unexplainable cusomerless thing into a business, let alone LITERALLY mortgage your future for it?
As others have said: No. Under no circumstances should you sell your house to fund... whatever this is. Bootstrap it nights and weekends if you feel passionate, maybe go find a co-founder if you can explain it coherently.
