My first mistake was choosing the builder. I wanted some custom features for the home, like quarter-log siding for the exterior and interior walls, timber ceilings, etc. They wouldn't do any of that. So my choice was to go with a true custom builder who builds one house at a time, or compromise. I compromised because true custom builders are ridiculously expensive and I'd never be able to sell the home. So the builder I chose would not do anything "unique" and they used the cheapest materials and labor they could find. I've never seen such shoddy construction. I'll have to redo a lot of what they did to get the house like I want it. They let me pick our their best materials for flooring, paint, etc. And they let me buy my own sinks and finally agreed to build a tiled walk-in master bath instead of installing a cheap drop-in. All of their materials were garbage, even their "top end" stuff.
My closing was a nightmare. The GC "guaranteed" me a date that the house would be complete, so I scheduled a move-out date with the apartment and scheduled movers. The actual closing was almost 5 weeks later. I was about 2 days away from having to move into a hotel and move my furniture into storage. I basically had to threaten the building company with a lawsuit. That was a stressful 5 weeks that I wouldn't wish on anyone.
I've lived in the house for about a month, and I have water coming in through the first floor, a hot water heater that constantly trips (probably bad thermostat), and a bathroom that leaks through the floor all the way through to the first level. I've heard that once you close, the builder drags their feet for warranty items. That's definitely true in my case. Oh and they left about a dumpster load of garbage - mostly leftover materials and some actual garbage, on my property. And they left about another dumpster load of stumps that they promised they'd haul away since early on in the build.
I owed $18K at closing, they were nice enough to let me know that about a week before closing. To this day I do not understand how they came up with that amount. I work with a guy who claims he owed almost $40K, so maybe that's not that unusual. It sure shocked me though.
I'm sure I can think of other bad things. Having said all of that above, I don't really know what advice to give anyone. All of the major builders have plenty of bad reviews, so you can't really go by that. If you can afford it, a true custom build is the way to go, but just realize that most folks living out in a rural area on land can't afford an expensive house so you might have issues of you try to sell.
I'm slowly getting over the whole frustrating experience. There's nothing like living out in the woods and having total control over your land and house. I was never able to do that in the military.
...I forgot to mention the part about utilities - you'll want to plan that out very carefully. My house sits 560 off the road. I did a lot of work myself, but here's about what stuff would've or did cost me: Driveway (concrete) $26K; electricity: $14K; water: $5K; internet: $3.7K. All of my utilities are trenched because they want you to clear so many trees out to go above ground. I don't know which is more expensive, but I'm glad I kept the trees.
