It matters what type of haunt and budget you have. There's haunts out ther that spend a 100k on marketing easy. There's a haunt here that has almost zero marketing budget its on there property and only have volunteers for actors but have been open for over twenty years.
Almost any 15 to 20k square foot building in a decent sized city will run you about 60 to 100k a year if the building isnt ran down and you need a sprinker system in it as well. Different things work for different people and budgets. I feel you should own your building or property to really be successful because it could take a couple of years to make real profit and I have seen property and buildings sold out from underneath people just when things started looking good. Landlords are greedy and will hire rent to if they see you doing good after lease or agreement is over and a new one needs to be reached. Hope this helps you because this comes from personal experience.
