Struggling to find rented

[crappyday2018]

Finally sold my house after break up last Easter. My buyer wants in early October.
My plan is to rent for a while so I can build up another deposit (had to reduce price of house to sell).
Problem is, 3 bed rentals are like gold dust where I live. I've viewed 3 in this last few days and they have been awful in bad areas. I'd even consider a 2 bed and let my 2DS share a room for a while.
I'm starting to panic. I have seen a lovely 3 bed near the school (perfect) but the rent would mean I couldn't really save much.
My question is - do I just take a house in a crappy area, or smaller than I need so I can save? Or do I find a decent house for my kids and take much longer to raise the deposit?
I'm on my own with the kids so I don't want to be anywhere too rough.

How old are your 2DS's? Nothing wrong with children sharing a room up until they start hitting puberty I think.

I’m also scared of living in a bad area but since it’s just for the short while, i’ll take the small house that’ll enable me to save what I need to move on. You don’t want to be stuck renting if you’re unable to save

Is there much of an age gap between your sons? I would hesitate at say a teenager and baby/toddler/young child sharing a room long term, as they're likely to have very different sleep patterns, but if they're close in age they'll be fine. My sister and I shared a room until I moved out to uni (so well past puberty!). It really isn't that much of a hardship, and means you can save quicker.

They are nearly 11 and 5. I don't mind them sharing too much really if its short term. I'm struggling to even find a 2 bed at this rate......
