For an auction purchase hard money usually fly. At the auction you normally need a $20k cashiers check at the auction so if you win you hand that over immediately. Then the rest of the fund are due in 24 hours. Hard money lenders usually want a few days to underwrite the deal and so typically the timeline wont match up. If you have a hard money lender that will do it then that is awesome and it is a possible strategy. I keep and distribute an auction list that I retrieve from a few sources. You can check out www.realtyhub.com if you want to try and go it alone.
I like the idea to refi your current residence and then take those proceeds and buy a new place. I like this because then you are adding to your portfolio. But if that is counter to your goals and you need all of that cash then you should sell. It comes down to what your end goal is.
Personally I am currently selling a condo I live in and plan to take the proceeds to buy a 2 to 4 unit property.
Reach out if you ever want more details. I like this topic a lot. Good Luck.
