Owning fire extinguisher is not a bad idea also. You do not have to buy one every month or every year. Once you buy it, you can use it over and over again (although you don't want to use it that often!). Unless it needs maintenance, you do not have to keep checking it. The maintenance is very easy. Some of them only require you to shake it once a month. Some others requires cheking twice a year. It will feel like buying something at a time but giving you protection for the longest time.
It also only demands a very small area of the house. You can just hang it on the wall, or put it at the corner. No need to worry to provide one special room for fire extinguisher. If you want, you can purchase fire extinguisher cabinets which will help you make the more organized.
