Barrie and Inga Adlington, of Birmingham, England, have just finished putting their three daughters through college. As empty-nesters, they are considering purchasing a vacation home in the United States on a lake because prices have dropped in recent years. The house might also serve as a retirement home once they retire in 6 years. The Adlingtons' net worth is $382,000 including their home worth about $266,000 on which they currently owe $44,000 for their first mortgage, with a $788 per month payment. Their outstanding debts in addition to their mortgage include $12,700 on one car loan ($249 monthly payment), $13,500 on a second car loan ($300 monthly payment), and a $25,300 second mortgage on their home taken out to help pay for their daughters' college expenses ($168 monthly payment). Their income is $110,000.
