He owes $10,000 in credit card debt, student loans, and property taxes.

This year I acquired my first multifamily property of 6 units that gets a true 11% yield in a B+ area.

I own a brokerage in Oregon and we actually have 2 brokers that are pretty inactive, maybe a deal or two a year, they pay their own expenses such as business cards and MLS dues and we are happy to have them and help them when needed.

(Question should be viewed as theoretical and does not necessarily reflect our true financial situation)

One way is to set up deposit-only ATM cards for each tenant (different banks offer these) that they can use to make the deposits but that you can deactivate if you're going through an eviction (provided there is an alternate method for them to make rent payments). 

That's right, I said it, because it's true.

That sounds too good to be true.

This is not true 

I just politely asked for their business card and told them I'd contact them later if I was interested.

I hate to be a cynic, but if something is too good to be true, it usually is, especially in real estate.
