Present Continuous or Future Simple?
1.I'm having / 'll have my house redecorated next week.
(Can we consider that it is a planned activity or just decision.)

Will, may or going to:
2."What decision has the management reached?" "They are going to reduce / will reduce our salaries!"
(intention or prediction)

3. I'll have to sell the house if things continue like this, but I hope there will be / may be a chance for the better.
(after hope we have to put "will" but at the same time they aren't sure what will happen?)

2- Intention- they have discussed it.
3- Yes
