First time mortage advice with poor credit record.

Hi just wanted your advice opinion, potential 1st time buyer currently live in my fathers house who has passed away and house being sold, will be receiving about 45k for my share of the house sale,

i am working salary 15k, wishing to get on the property ladder, was planning on putting down a 35k deposit on a 70k house, problem is my credit record, have several defaults (payday loans) barclaycard not for large amounts albeit defaults, recent ccj from severn trent for £300.00, these will all be settled before i apply.

would i be able to get a mortage with such a large deposit, or should i rent for a year or two improve my credit record then try then.

Thanks for reading
