In need of a 3 bed property

Unsure if this is the right place to type to use to find a property for my twin sister and her 4 children plus 1 dog.
It’s a long shot but they are very well mannered family in a bit of a sticky situation and in need to move out of their current home due to separating from partner and the landlord upping their rent during lock down. She is desperate to find somewhere within the next 2 months ideally with max price being that of £650-£700 and situated in melton mowbray.

I do apologise if this isn’t the done thing on here, I am just trying to support her in any way that I can. Thank you
