I am single, have $5k left on my car loan and $5k credit card debt.

For instance, I know a few shop owners, mechanics, restaurants, etc. and got permission to put my business cards on the cashier counter.As far as the numbers, if they work and you can see them working in the near future, then why not?

I know for sure that you can give Home Depot cashiers credit card numbers over the phone to key-in for a purchase.

Craigslist ads (post about twice a day and reply to every for rent post in your target area), Direct mail (send letters/post cards to every foreclosure filing in your county and then follow up with them again about 3 weeks before the foreclosure sale is set to happen), Drive for Dollars (when you see a house that is in need of repair, knock on the door, ask about the owner's plans).

Even credit card debt is better, although higher interest rates, it is unsecured debt. 

Tenant is required to have a bank account or credit card to pay online.

If you do not have one, that is, if you went into landlording with no trusted lawyer's card in your wallet, you made a big mistake.

This card also has a credit limit of $30,000. 

The same common sense rules apply to most things on your credit report - maxed out revolving credit cards and late payments hurt your score, while responsible use of debt and on time payments increase your score. 

They think they need websites and business cards and all this stuff before they start implementing their marketing.
