Do you follow the 70% rule for your averag flip in S. Florida?

[Mitchell T.]

Hey friends, a few question for the S. Florida flippers. Getting properties at .70 ARV minus repairs has been difficult for typical 250k-350k ARV. After running your numbers:

1: What are you realistically looking for in terms of profits (% wise or hard number)?  

2: Is it unwise to go for properties at a 20%-23% of ARV - repairs range?

3: What is the lowest % you would be willing to go down here?

Thanks for any input, and please let me know if anything I said is dumb or doesn't make any sense.
