Ok. A second home- even a motorhome or trailer. as long as it has a bathroom and kitchen, all the mortgage interest is deductable.
Tax free bonds- with a minimum purchase amount of 1000.00 dollars
A home equity loan spend it as you wish, interest deductable.
Another possibility. Trqvel expenses. You make a trip fly or drive, take 14 days, spend one day on business the rest on vacation. Sure you deduct the daily expenses for food and lodging for the vacation days but take the full air/drive costs.
