I think downsizing, and redistributing that value of your house now instead of when you die, is an excellent plan.
^Yes, giving away all your money just before you reach old age is a fantastic idea.
Being old is really cheap and there is no way you are going to need that money for anything hmm^
Just owning a house isnt a magical solution to money issues in old age. Eventually, you have to sell it to access the cash, and it is worth considering doing so sooner, rather than later. Doing so in middle age, before your abilities and health begin declining may help preserve your ability to care for yourself and lower your living expenses. If you wish, your children can have some of their inheritance when it will do them more good, and your smaller, place still has decades to increase in value to be sold for your needs, or end up in your estate to benefit them. Either way, if you already see your house as an asset, and plan to get the cash out for YOUR benefit then you and I are actually on the same team.
My point was some parents should consider that leaving the house to their children is not the best way to assist their children, if assisting their children is a goal. To carry on living alone sometimes in quite a pitiful state as their cash income is eaten up by the house, and their children have moved away for jobs and to afford housing s not the best plan if accessing the cash can put them in a more manageable property, either nearer their children, or allowing their children to stay nearer to home. They struggle to leave their children this valuable asset, but it's value diminishes through neglect, their childrens concern for the house or its contents are diminished by distance, and the benefit of inheritance in late middle age is not as great as half the amount decades earlier invested into their own home would have been.
