wholesaling

[Juan Najar]

i wanted opinions on how others get to their maximum allowable offer (MAO). I get three comps from redfin that are the closest in radius to average out an ARV. I then multiply by .7 and then subtract the repair estimate cost of $10-20 a sqft. I then take out my profit of about 5,000. Is this a good formula to go by? if not what formula are others using? is there a better way to get comps for free without MLS access?
