We hid Easter eggs, put out chocolates around Valentine's Day, etc. 

It can leave them in a financial pinch.

This year, I gave a box of Godiva chocolates. 

It does give me comfort to know that if he's in a pinch again, and doesn't get bailed out, that those kids will have a place to go.Oh, and we found out this weekend when we got rent that he just had cable installed a couple of weeks ago (we found out b/c the cable company disconnected the other tenants satellite dish when they did the install, and they had to pay $50 for the dish company to come out and fix it).Speechless.

I do all my repairs on two SFR units, but i would pay that price if I was in a pinch. 

If not, they will end up in a pinch, won't pay rent, and will have to be evicted.  

Its probably great now while prime is 3.25% (since May 2009) but it may not always be 3.25% in the future and if it rises your monthly cash out flow will be pinched either on your rental property end or your personal income end. 

If you buy a marginal deal, you'll really be in a pinch if things get bad.Don't give up.

I see most landlords accepting ACH for the bulk of their electronic payments, and setting CC as an optional feature that the tenants can use in a pinch, but the tenant pays a convenience fee to cover the merchant costs.As far as to the original question of using Square.  

Like a box of chocolates "you never know what you will get".
