Iâ€™m contemplating getting into the spec house business by building a small spec that Iâ€™ve designed. Iâ€™ve read all of the previous posts on spec houses and understand the potential risks involved, so I have a more pointed question. Iâ€™ve found a one acre lot that I like quite a bit that is on the edge of town. Iâ€™ve run the numbers for the construction and have figures that I like for everything but the water and sewer hookup. City water and sewer is available but would be about 250 feet from the house location. Can someone give me a rough estimate of how much it would cost to tap the water and sewer mains and run the lines 250 feet? Iâ€™m located about 20 miles north of Des Moines, Iowa. The street is just seal coated and does not have any curb. There should be enough fall for the sewer line...
