we are looking at a very nice home for possible purchase. However there is a second home on the property with tenets in poor condition. It appears to be added on several times without any sort of thought put into it. I find it hard to believe that people live in there. It’s obvious the roof needs replacement as well as the furnace but what concerns us is the septic. The main house has its own septic which works well. However the tenet house only has a tank without a leach field. There isn’t really room to put one. I’m guessing this isn’t up to code by any means or possibly grandfathered in as it’s an old structure in a small town. We would love to rehab the house but it probably would be a total gut. Investing in that would be frugal if we can’t figure out the septic issue. Since we haven’t decided to offer at this point we are avoiding calling a building or home inspector. The homes are owned by an LLC and they advertised the second home as only needing cosmetic TLC. Of course we don’t believe that to be the case. It probably should be leveled. But my question revolves around the septic which is acting more as a holding tank than anything. Can the tenets remain there with the rental in this condition? If we did decide to purchase we’d just like to gain perspective on which way might be the way to go.
