The landlord will look at any tenants, and judge them on their own merits so housing benefit etc would not be a problem, however, to pass through referencing, any tenant would need to show an income of £51,000
If unable to do that, a guarantor earning £62,000 would be considered. The landlord will not consider a guarantor to cover poor credit score.
There are to be no pets, or smokers, in the property
