Help with website formulas

[Riley Holt]

Hello all. I am gearing up for an ad campaign and getting my website going. At present I am trying to find off market deals for buy/hold, flip, or wholesale the properties that fit my criteria. I want to be as transparent as possible with my numbers and share them with the seller and possible buyers if I end up wholesaling them. 

Right now I'm thinking with wholesale...75% of ARV - repairs - wholesale fee.

BRRR....75% of ARV - repairs.

Flip- ARV - anticipated profit (30K?) - repairs - 10k (for listing and closing)

Are these reasonable? Also, how does one calculate their wholesale fee? Is it standard across the board or depending on the property type. I know 10-15 k gets thrown around as a wholesale fee a lot but I’m not trying to be too greedy. 

Any and all advice is greatly appreciated.
