Hard Money Lender For a Rental?

[Amauris Lora]

Hello Everybody 

I been putting together a deal and the numbers are good at least for what I see but because the situation of the seller I have to move more fast than the conventional way with cash that I don't have right now so I was thinking in use a hard money lender for the purchase and then refinance the deal to long term

what do you think about it? I'll be more than grateful to see your respond and thanks for take the time for it
