(quote terpe.)
One of the key issues in the application of the General Visit visa is that of clearly demonstrating and convincing the ECO that on balance your reasons to return to your home country outweigh those of overstaying your UK visa.
The ECO needs to see overall strong social or economic ties. He needs to feel comfortable that your whole application gives him a warm satisfied feeling that you intend to leave the UK at the time you state.

when we were refused refused, for this reason, i asked what sort of ties,"she should buy a house was the reply"

so not being negatve terpe just realistic, visit visas are few and far between, would hate for songz to waste his time,energy and money not to speek of the dissapointment and stress levels
