AMEX offered me 25k personal loan at 8.98%- how to best use

[Jake Walroth]

So I was logging onto my AMEX Account to pay my bills, and I got a pop-up saying you're pre-approved for a 25k personal loan at 8.98%. They also said this wouldn't go on my credit score. I usually spend about 3-5k with AMEX a month for flights and travel for work, so I assume this is why I was offered. They payment plans offered I can afford from my work income. I'm looking at investing in my 2nd property and have been thinking about a value add multi-family. This would seem like a very appealing tool to use either for a down payment or needed renovations. I have about 15k saved up in my bank account, my thinking is to use this in combination with the AMEX personal loan to fund DP and Renovation. Has anyone had experience in using something similar? I've been pre-approved with local credit union already, but I like the idea of the simplicity of this AMEX loan. My plan was to treat AMEX like a HM loan, and once reno is done, try to refinance into a conventional to reduce my debt. Any opinions, advice, etc is much appreciated.
