to the guy that said open up a shop w/ lifts and techs---i dont know about where u live but theres a hobby shop in valdosta where you pay $5 an hour and can use all of their equipment and theres a couple of people working there.
storage facility doesnt sound like a bad plan...you cant do much with real estate at 80k, but if you started up a smaller business and made some money, then you could do real estate on top of that.
you dont want to open up a restaurant, it is not worth the pain and agony you will go through..unless you open up a hooters on the beach. business at these places during march-october = AMAZING!! besides that restaurants are bad news.
this guy in valdosta opened up a pizza place, $5 pick up one topping--dont have delivery...and apparently in the year he has been opened he upgraded from an [01 maybe?] dodge dakota to a dodge srt-10..and hes opening up another pizza place[may be open already]
just pay more attention to your surroundings and what seems to be busy and what seems to be taking your and others money. try to think about things you have never considered before.
another good idea that probably has low cost is open something like a ready ice. in my town theres probably 10 of these..you pay 1.25 and get a 20lb. bulk of ice or a 16lb. bag.....no labor fees, just stock the ice yourself. it's a good deal for the customer and over time will make you money.
probably cost a little more than 80k, but there is money to be made with having gas stations too.
what do you do for a living now? do something that u could use that to your advantage. my dad is a marriage and family therapist, he recently wrote his own book...it hasnt taken off yet but it's slowly getting there. he will make money from the book and become more famous--thus being able to charge more money at his outpatient office.
