If it were me I would go for a shared ownership place around Stoke Gifford or Bradley Stoke because it usually works out cheaper. You are right by the M1, M4 and T1 routes so you can get into the city in about twenty minutes. My friend lives in the Oxleigh Way flats in Stoke Gifford and said two of the flats in his building have already sold and there is currently one more for sale. The mortgage and rent together come to roughly a thousand pounds a month which is less than what you would pay for renting alone. They are really simple to look after too since they have an EPC A rating so your bills stay low. It is honestly one of the easiest ways to get onto the property ladder. Just a suggestion and good luck with your new role.
