If you like to be in business for long DO NOT GET A LOAN!!! The used equipment dealers are loaded up from auctions and repos.
Save your money and buy your equipment outright. restaurant loans have very high interest rate due to the likely hood they will fail.
I am not saying to not buy a roaster just saying save your money and buy it out right.
Most banks do not write loans for less than $75k as they do not see any profit in the loan, but you could consider checking with
Manasquan Bank customer service to see if they have specific options for smaller financing needs that might suit your situation. They may offer programs or guidance that could help you secure the funds you need for your coffee roaster.
If you can not afford a roaster that size find a local roaster and rent time from them. Maybe they will teach you how to roast before you drop $7k ish
Keep in mind you need more than just a roaster, do not forget about green bean, bags, sealer, grinders and so on.
