I personally wouldn't do this deal, it sounds way over-leveraged in my opinion. We all have our own risk tolerance but i'm afraid this one will not end well, unless of course you're properly reserved to withstand a storm (That will come because they always do). This will help in the event of something major that needs fixing or if you stay vacant and need to hold the loan down for a while.
I Personally love the BRRR strategy. Out of my handful of properties, I've done 2 BRRR's one of them pulling out all of my down-payment and rehab money completely but I was only comfortable doing that because the final loan ended at 60% LTV with 40% equity and I have 1 year of reserves for each property I own. I prefer to stay a little more conservative as i'm in it for the rest of my life and am trying to keep my portfolio at 50-60% LTV in its entirety.
On the other hand, this property could go very well for you and you can win! Just have to be able to weather the storm, that's the most important part.
Best of luck in your endeavors
