Start with a sanity test.
Trucks per day = average daily traffic X 0.04 X 0.15 X 0.17
If ADT is 25,000, expect 26 trucks per day.
If exterior price is $45, gross sales would be $1,170.
312 days X $1,170 = $365,040 annual revenue
If operating expenses are 70 percent, net operating income is $109,512
$109,512 / 12 months / 1.5 debt service = $6,000 (rounded)
$6,000 is maximum allowable monthly payment that makes financial sense.
$6,000 is equivalent monthly lease payment for $300,000 in assets.
So, how likely is it that this site location would attract an average of 26 trucks a day from Highway 81, the principal road?
Assume this is possible. So, how likely is it that a truck wash could be developed with $300,000 in assets?
Considering 55’ turning radius and 80’ truck length, pad site would require minimum of 18,000 SF of land and 2,400 SF building.
Assembling nearby lot would provide enough property, barely.
2,400 SF steel building, permits, delivery and install is about $180,000. Hand wash and support equipment is another $75,000 to $100,000. Plus land cost.
This is why developers generally look for site locations with the potential to wash 40 to 50 rigs per day.
