Things you can do to cut your living expenses without lowering your standard of living:
1. Give your house to your children via an Irrevocable Trust. Then rent the house and live there. Have an estate attorney draft the documents and provisions.
2. Sell your home to your kids and live there...maybe pay rent, maybe not.
Gifting or selling your house to your children and then living there is the only option that will both maintain your lifestyle and reduce your costs according to Timothy Speises of the firm, EisnerAmper.
As long as your children are willing and able to pay for the property taxes, maintenance, repairs, and any remaining mortgage payments, your house costs will be low...maybe even non-existent.
