0% promotional APR cash advances for financing real estate?

[Adrian Chu]

Anyone use 0% APR promotional interest rates for credit card cash advances to finance real estate transactions?

The only caveat is that sometimes they have a minimum cash advance fee, similar to a loan origination fee, usually like 2-3%

I used the checks they'd send back in the day to get cash and still use the hell out of my credit lines for supplies on my rehabs.  Need some pretty big credit cards to make that actually buying a house, but it can be good down payment or supplies money.  Using the offers can make a lot of sense as long as you do it intelligently.  Back in the day I was flying all over this country for free because I was spending $50k/mo on building supplies on my rewards Amex.  

Not that you should plan on it, but I did default on some on cards when the bottom fell out in 2007/8.  It wrecked me at the time mentally since I'd never so much as paid a late fee on anything the first 35 years of my life, but in hindsight it was smart having that money unsecured.  Also, just know those people are not your friends if the going gets rough, I was working like hell to keep the biggest one paid and they got a payment 3 days after the due date (that I mailed 10 days before) and they took my rate from 5% to 30% on like $40k when I was struggling and wouldn't change it.  I intentionally never paid that one back, even when I got back to where I could.

The math works if your credit is great.  At one point my cards were at 5% and my HELOCS were at 7%, go figure.
