I rent but tankless is awesome, if its the kind that has hot water running 24/7 your electric will go way up, the one I have heats it only on use and the electric is still higher but it is way worth it bc the hot water never runs out. down side to any one is they have to be completely replaced every 10-15 years mines 6 and has had 2 leaks fixed. still worth it but other huge thing is you have to have good water pressure or you will never have hot water anyways
