With 4 growing children? That'd be easy, sure! I'm sure a landlord would love that.
Even if it was physically possible to get 5 people in to a 2 bedroomed house, it's likely that she would be turned down by a landlord.
There is so much competition for private rents that each house had a number of people going for it and the landlords choose the best candidate.
If you were a landlord of a 2 bedroomed house, who would you choose:
Candidate A - professional couple both earning a reasonable salary, no children, could still pay the rent even if one of them lost their job; or
Candidate B - single parent, relying on UC and Child Benefit to be able to afford the rent, and wants to squeeze 4 children in to 2 bedrooms.
The OP's situation has highlighted a knock on effect of the housing price crisis that I'd never considered before as I am (fortunately) of an age where I did manage to get on the property ladder when housing was more affordable.
Had she and her partner/husband been able to afford to buy a property themselves, they'd have more than likely had life insurance to cover the mortgage and she wouldn't have to pay £1,750 out each month for accommodation.
Very few people that don't need life insurance to cover a mortgage would think to get life insurance otherwise.
So, not being able to afford to buy a house when she was part of a couple has condemned OP to potentially a lifetime of overpriced rents.
If there's one lesson to learn from this for others it would be to seriously consider life insurance for your partners/husbands, even if you don't own a property and especially if you have children.
