Hi! I just got my visa and my hubby and i are going to stay at my inlaws' place. When i applied for the visa, i didn't mention there that my inlaws are living with lodger. A family, consists of 2 kids and the parents. Anyway just make a good letter and description of the house, size and nos. of the room are very important.Also attached a mortgage or any evidence that you own/renting the place.I also provide the pictures of the house with my husband by it, maybe it helped my application.
Financial support should be provided by the husband not by anyone else. It is the major factor that they looking at. He should show a healthy savings. If not the application might not go well or surely will be turn down.
