Hi looking for some advice from anyone that has any experience of moving during high school applications?
Basically, we’ve been trying to sell our house since Dec 2017 because of work and hoped for our eldest to have a good year in Y6...fast forward a year and we’ve have had two sales that have fallen through close to completion for totally different reasons which has been so stressful to say the least!! When we got our second buyer in Oct 2018 we hoped that we would be in our new house in order to make the deadline for the new address submission for applications to get her into our preferred high school in the area we are wanting to live.
Anyways, because of solicitors dragging it out we missed the deadline for submitting our new address that is well within catchment. But we thought that once we moved we would appeal and have a good chance etc so didn’t worry too much. This was until our second buyers only went and broke up last week and the sale fell through!! We didn’t put down any other high schools as it’s an oversubscribed school anyway so wanted to put it as our first choice! And now we are in full on panic mode of what to do!! 
We have already appealed last year to get her into the local primary feeder school to the high school in the new area - which was successful and she has a place waiting for her in Y6.
I’m pretty confident we will sell our house again in the coming months as already had a few offers and the vendors of the house we want have told us they will wait. So with the panic of being in a good position for appeals (as it seems it’s going to all that again - great!! 
) we are considering renting a small house we can just manage to afford near to the house we want to buy so that she can go to the new school and have a decent amount of time to make some mates as it’s such a big thing.
My main worry now is will I have a chance of appealing if we are renting but still own our current house? My daughter will have moved schools (it’s a good hour away) so I’m hoping that shows that we aren’t going anyway and reminding in the catchment for the high school for the foreseeable future but without a “permanent” address and still owning our current house will it be seen as us trying to pull a fast one?
Has anyone had to do similar? How did you get on? It’s keep me up at night with worry!! Nightmare situation
