Deductions & credits

Similar fact situation as above, but I have questions about "continue to enter your information" after you've reported type of investment sold was "everything else."

 

What is the property "sold"?  Does one simply enter "Unsuccessful attempt to purchase a specific business" or should one enter the name of the business?

What is the date the property is bought and sold?  Could one put the date of the letter of intent as the date bought and the date the transaction fell apart as the date sold?

And would "cost basis" simply be the amount of capital expenses?
