Does anybody here know Fannie mae or Freddie mac's rules on whether can use projected rents of unfinished property for DTI?

For example, if I want to refinance property A but I also have an unfinished property B with construction loan. Can I count the projected income of property B as my income?

I know a few lenders can do that but most lenders can not do that. So what’s Fannie mae or Freddie mac’s rules on this? I just cannot find that information online.
