This x 100. With me and the wife doing this property together we know what the other person is doing at all times and have systems in place. 30 Mins max on one of these properties. On a single simple vinyl ranch property like this we'd do it for around $200-$225 but when they are giving you 30 units (with the assumption they are right next to eachother) I would gladly give them a price break for a full days work with no travel time. (Volume example for reference only) 125$ a unit at 30 units... $3750 - ~$550 in expenses leaves you 3200 out the door. Drop that to even 100 a unit even.... $100 a unit at 30 units.... $3000- ~$550 in expenses... still $2450 out the door for a long days work.
I don't see $3200 a day for a single rig with two washers and two employees as lowballing, but maybe thats just me.
