There is a real market in BMV properties but these will not fall into your lap. There will be options to flip properties but there also will be chances to buy and hold longer term.
I tend to look towards those which look a little battered and bruised and unloved. I like to do them up and then hold longer term or flip if the price is right.
I live in the north of England where it is possible to obtain double digit rental yields - therefore I tend to buy, do up and then rent out. However, if there was a chance to flip a property for a decent profit I would not be against this.
