@Tony_M and others - First understand that I have a day job as a Tiger Conservationist that pays very well.
It is very possible to make money with only 5 tables. The most important part to consider is not how much you make but rather how much you can keep after expenses. We pull in just at $70,000 in profits each year. The keys to success here were low rent and utilities and it takes only 2 staff members to run the site, and most often times only 1 person to operate.
In our situation I bought the site (10 acres with a house), I rent out the left side of the house out to college students for about $1,200 (which includes 3 bedrooms, 2 baths, living room kitchen and dinning with utility room). I also managed to set in 4 rental lots along the back 10 acres, of which 2 are already rented out for an additional $500 per month.
There is also a metal building that I am renovating for use as either a produce stand or a cafe. There is additional development available for me to either run a farmers market or a mini-storage complex and most likely both if I decide to go that route.
But back to the house. After renting the one side out I then took an old attached den/family room with fire place (16'x16.5') and 3 car garage (25'X32')and made use of a 12X10' area as an office area and then added on an additional 500 sq. ft. along the back side and converted it into the pool hall. The total amount of footage is just over 1,600 sq. ft. I'll try to set some pictures of the development when I can take time to upload them etc.
The utilities are all tied to the existing home so my expenses there are covered by the rental units for college students as a dorm. The rent is zero since I own the house and already covered the mortgage with the existing income. This pool hall is geared towards neighborhood youth and young people looking for something cool to do in the evenings so it all works out.
The site sits on a busy corner with average drive by traffic counts at 6,710 vehicles per day. There are 3 school districts located within 8-10 miles from the structure.
What's really cool is that after about 2-3 years of operations I should be able to take the operations here and use it for the needed experience of running a larger more profitable operation. I intend to set it in with just about any bank to cover needed loans for building a larger facility with beer sales etc. My thoughts are 10 to 12K sq. ft. but I want to be sure that I control (own) the real estate and equipment or in my case at least be buying it. That operation will be set in with 44 tables. I plan to run 34 of the 8' smart tables and about 10 of the 9' smart tables.
