I was thinking about using an unsecured loan to obtain a rental property.

Here are some of the options for investing your retirement accounts: * Real Estate - including apartments, single family homes, and duplexes * Commercial property, developed or undeveloped land * Mortgages/Deeds of Trust * Publicly traded stocks, bonds, mutual funds * Private Limited Partnerships * Private Stock Offerings, Private Placements * Private Limited Liability Companies * Secured and Unsecured Notes * Judgments/Structured Settlements * Tax Sale Certificates * Car Paper * Factoring * Accounts Receivable * Commercial Paper * Equipment LeasingYou can also set up Self Directed Coverdell Education Savings Accounts for child education expenses and Self Directed Health Savings Accounts for health care expenses.What if you had a child who was 5 years old and you opened a Coverdell account for them with $500.

Banks will offer you sizable unsecured lines of credit once you have an LLC (or any company) profitable for more than two years, for instance.

For a cash buyer that would be a little over a 10% annual return, not terrible for those sorts of unleveraged deals.

In other words, the only thing the bank can do is foreclose - they cannot come after you for unsecured portion of the HEL.Good luck putting this deal together.

You have a LRO which is unsecured and they can change it at anytime

The unleveraged strategy worked out for me in that sense as the cash flow was strong from day 1 to cover these expenses.

@Nick CoonsCredit card charge is unsecured.
