Conversely if your wash requires a new owner to make an investment (like a new IBA or to add equipment like softener, RO, etc) then a multiple lower than 3 is probably in the future. Get the equipment room looking clean, orderly, everything working properly so it shows well - similar to when you sell your house.
That's a good point Soapy. Sewer tap fee's here are around $35,000-$40,000, water tap fee's can run about the same. One of the biggest killer of the last car was project we've been involved in is street improvements. Last car wash project they wanted almost $500,000 in street improvements, sidewalks, left hand turn lane etc. it killed the project.Compared to land that has never been developed you do not have to pay the hookup fees again.
