Housing for a family of 3 arriving in August 2023

Hi, I am in the look out for a property to rent for my family. We are currently in Ghana with an on going processes for my admission at Teesside for Autumn term 2023. We are looking for get a nice 2 bedroom anywhere in Middlesbrough or nearby towns. I have marked down a few properties but I need a uk phone number to even be able to ask landlords if they did accept a family of 3.
I am open to advice and directions from others here with experience on how I can work this out. Thank You.
