Hi all, I have a park that I’m attempting to evaluate that is off-market and in the same city as another park of mine. This particular park is about one block outside of the city limits but is on city water with a 1:1 ratio of homes to septic tanks. From my understanding, septic tanks should be pumped between 3-5 years, but in the 19 years the owner has only pumped 4 tanks. What would this mean for the leech field? The park has 8.7 acres of land with only 26 spaces, but I am not sure how large the leech field is. What are the questions you would ask the seller to attempt to get an early impression of the health of the system?
