My suggestion is to push capture rate, demography, P & L line items and equipment issues to the side for the time being and focus on the fundamentals of the business.
You said the “ask” is $225,000, assessed for + $300,000. The land is maybe worth $150,000.
Using standard criteria, the financials you presented would support maximum allowable monthly payment of $2,200.
$2,200 translates into loan amount of about $250,000 based on standard conditions and terms.
If the land is $150,000, this would leave $100,000 for improvements assuming bank will accept and finance bid price of $150,000 for property.
If the bank requires loan-to-value of 60 percent, the equity injection to acquire property would be $100,000 ($250,000 * 0.4).
Gross $65,000 less operating expense ratio (benchmark) equals $39,000 (EBITDA or NOI).
$39,000 less property taxes (assume $8,000) and debt service $26,400 ($2,200 * 12) equals $4,600 earnings before taxes and depreciation (EBTD)
$4,600 / $100,000 = 4.6 percent return on cash (ROC)
ROC for typical “new-to-industry” self-service, prior to real estate melt down, was 35.6 percent.
ROC of 35.6 would require EBTD of $35,600 ($100,000 * 0.356).
EBTD $35,600 + 26,400 (debt) + 8,000 (property tax) = $70,000 EBITDA or NOI.
$70,000 EBITDA / 0.4 (expense ratio) = $175,000 gross sales
$175,000 - $65,000 = $110,000
$110,000 would be increase in sales needed to achieve ROC of 35.6 percent.
$175,000 / $65,000 = 2.69
Can you deliver a business plan capable of growing current sales by a factor of 2.69?
As a general rule of thumb, start-ups should not plan to capture more than 25 percent market share.
$175,000 / 0.25 = $700,000
So, the first sanity check would be to determine if the trade area has total potential sales of $700,000.
And so forth. Hope this helps.
