Credit cards cash advance to fund down payment

[Pirom Ting]

My wife and I are thinking to take out cash advances from her credits cards, to gift over to my account for a down payment on an investment property. We're looking to get $15K-$20K out of it.

We're looking for advice on whether this is a good idea or not. 

The property we're looking to buy is between $75K-$100K with repairs needed. 

In the end, worst case scenario, we would be able to sustain payments on the credit card and the mortgage if necessary. We are just trying to get the down payment faster than just saving up for it.

Thanks
