Need help understanding Refi in the BRRRR method

[Evan Holly]

I'm a rookie investor who has come across a deal that seems to work well, but I could use some assurance or advice.  Here's the sitch...

I come upon a property in Alabama from a wholesaler for 37k. Rehab estimate is 20k, but let's go with 23k to bring the total to 60k. I have 60k hard money to pay for it. The ARV should be 80k. I'm going to use it as a short term rental, and should average 2k per month, conservatively.

I'm unsure of the next steps and order, but here's what I think.  Get appraisal.  Find a lender with a better rate.  Get up to 75% back to pay back my hard money lender (60k if it appraises at 80k).  Repeat. 

Am I missing anything?  Though I have great credit, I fear that I won't be able to find a lender with a better rate.  

Thank you!
