Uni housing

I am really confused here. I know everyone says book uni 2nd year housing super early as early as January of your first year, but during January I had no clue who I was going to live with. I now know who I will mostly likely be living with second year so we have started looking for houses of course first problem is that their simply is not enough housing for everyone I knew that coming into this. However the second problem is that everyone I have called has told me that I would need to move in basically almost immediately but I can’t even do that till late may because of accommodation contract and even then we would barely be able to afford to pay the rent over the summer. However are people booking houses to move into for may-August??

For accomodation which is targeted at students, the landlord wouldn't expect tenants to move in immediately. They would have tenancy agreements with start dates in August or September, as their current tenants (students) won't be moving out until early July.
So it sounds like you're looking at "regular" flats and houses, which are potentially vacant right now, or which will become vacant soon. So, unsurprisingly, the landlord wants tenants who can move in quickly.
How are you searching for accomodation? Have you tried googling for "student accommodation area"? (Where area is the name of the town / city / area you want to live.) They key word here is "student".

Yes I have been searching for accommodation that is for students or student friendly but still they want me to be available from basically right now -may. I think maybe it is because I am looking for 2 bedroom places and maybe they are uncommon for students as they go for bigger places ? I don’t know . But the places I am looking at are for students. Thank you for the response
