Good or bad idea can be judged with sanity test.
Based on loan-to-value 75 percent and standard conditions and terms, debt service would be $96,000 plus $15,000 property tax (WAG) equal $110,000 fixed cost.
($1,400 / month / wand-bay X 3 bays X 12 months) X 60% = $30,000 gross net
$110,000 - $30,000 = $80,000
Cars per year = $80,000 / $8.00 average price - $2.00 unit variable cost (net site)
Cars per year = 13,333
So, after accounting for wands, in-bay needs to wash 13,333 cars to break even.
Traffic 16,145 is capture rate of 0.27 percent. Benchmark is 0.29.
26,666 cars (capture 0.53), would generate profit of $80,000 (13,333 X $6.00).
$80,000 on $375,000 equity is return 21 percent, 36 percent or more is typical.
So, sanity test becomes is site location characteristics strong enough to capture twice what the benchmark captures?
