Selling property within probate within 12 month not possible

Form IHT 405 Houses asks if we intend to sell properties within 12 months of date of death. Is it a must to fill this out and stick to the answer? We think we will not manage within 12 months as it took us almost 6 months to clarify the estate and debts and according to HMCR it takes 5 months on average until probate can be approved. What are the implications if we answer no? Is it a problem if nevertheless try to sell asp. after probate. Are there exceptions to have more than 12 month time? And what might be the advantages/disadvantages to include it in probate time? Thank you!
