I have looked into:
- Storage units, great idea, but around here minimum investment would be about 1 mil.
- Automated car wash, tough to get them built fast enough around here, before there is one across the street. Min investment about 100k
- Liquor store. Tough to get a license, almost need to buy some one out, or have friends on city counsel. Min investment varies a lot, but for $50k you will get going. Still one of my favorite, maybe it's just the idea though...
- Mcdonalds, again need like 250K liquid, and another Million in the bank.
I have looked into just about every imaginable franchise, from dog poop scooper, to lawn cutters, to hotels... In my opinion most that are solid money makers, cost big dollars to get into. They are more like investing in a bond, Pay up front get slow constant returns.
I have never looked to seriously into any restaurant, this is mostly because I have a friend who owns a successful pub. It is a small place seats about 25 max, it is always busy, but so is he 7 days a week 16 hrs a day. Derek and I were watching the sopranos late one evening after he had closed, and on the show they were at that Italian restaurant they always go to, anyways the owner of the restaurant, says at some point "owning a restaurant is like owning an elephant, sure it sounds cool, but in reality, you feed it and feed it and feed it, and one day it shits on your head". Derek looked at me and said you have no idea how true it is. That was several years ago, he still has the pub, he is still single, and still works 16hrs a day 5 days a week and probably 4hrs the other two. From what I have seen you really have to love it to do it.
I think for my next go around, it will either be something very basic with almost no investment other then my time and some equipment, or I will flake right out and buy an automated car wash and put it in a new development.
