Hi leonardo,
Im having a little difficulty understanding your question.

Are you asking if its possible to consolidate unsecured credit into a new mortgage / home loan?
If so, sometimes it may be possible. If you found a home (perhaps a foreclosure?) that an the bank's appraiser valued at 30 to 50% higher than the purchase price (for instance, a property is valued at 120,000 but the person wants to sell and could care less what he gets, the purchase price could be 60,000... you'd have an instant equity of 60k to work with making the Loan to Value only 50% - you could get a loan for the purchase price of 60k PLUS whatever unsecured debt you owe (lets say 13,000)... and get the total mortgage for 73k.. and it would all be "secured" by the house value.
Some banks however only let you ask for the purchase price. And I wouldnt really recommend doing that anyway since you would then be paying interest for 30 years on that unsecured debt...
