Financing first BRRRR

[Account Closed]

I’ve been doing paralysis by analysis till my mind is numb. Ready to take the plunge but would like advice on how best to leverage my funds:

Savings: $50k

Credit: 800+

Credit card/vehicle/student loans: paid off

Location: Charlotte

Market: SFH or Duplex

I know I want to put little into this first deal but can't swallow the fact of shoveling out the PMI when I have the funds. I'm interested in putting the money towards repairs and doing a refi. Any suggestions on conventional loan or FHA? % of savings to invest in?

Thanks!
