Investors & landlords

Hopefully it is okay to ask a couple more questions on the same issue:

1:  Assuming my son pays the same as my basis for the house, meaning no gain for me,  is the Form 709 all I need to file?  Or, do I still have to file a Form 8949 showing no gain, or loss?

2:  When determining actual cash value, can I determine that myself based on comps?  Once that number is established can I deduct from that value what it would have cost to sell the home and needed repairs?
