I will agree that something is only worth what someone is willing to pay. And just because someone is willing to pay an amount doesn't mean a bank will loan it.
I fully agree that a commercial appraiser may not know anything about carwashes; my bank's DID NOT many years ago and I had to research the appraisal myself and find the errors in the appraisal to get financed. I endured a scolding by the banker but got my loan to add on my detail shop.
That's why it's smart business to employ some sort of well-thought-out exit strategy. Those of you who built a wash/detail/lube/laundrymat from the ground-up; think back on all the planning you did. Careful, well-thought out preparation goes into building. Appraisals, projections, market research, comps, car counts,
marketing plan, contingency plan, business plan.
If you did all this careful planning at the start, then worked the business, refining operations, developing strategies for purchasing, sales promotions, maintenance schedules and logs, safety procedures, added service offerings, etc., it only stands to reason that you would put similar effort and planning into your exit strategy.
Yes, banks have their; rules I know. However, rules can also be flexible. If a well-run business is marketed and presented professionally and thoroughly to the banker, he/she may look upon the deal more favorably than one that is supported by less.
