1. The $123/SF is based on what the county will allow me to use to based my estimate to determine if I will be above or below the 30k, based on some data they have available. She mentioned which documentation this was based on but cannot recall.
2. I was under the assumption that this was a fairly long process requiring testing, the proper insurance..Etc. Would that be worth it for potentially building a handful of structures in my entire life. Are you knowledgeable about the process? I would love to hear about it if it is indeed not too time consuming.
3. I am a licensed residential structural engineer (PE), I design mountain houses for a living so I would say that I am pretty knowledgeable on the subject.
4. I have not, but I have already got my plans drawn and details figured out. I have never done it per se but know exactly how it should be done. I am fairly handy as I have done some remodeling work. I think that between my knowledge from work and own research, I should be able to figure it out.
@Joshua Strickland, that is a good point but an existing cabin here is around 300k min, market is nuts with very low inventory (touristic destination in the Appalachian mountains). My goal with this small cabin is to place it on the same land as my house. The whole cost should be pretty minimal (compare to 300k) and result in a decent stream of income which should offset most of my current mortgage (the whole house hacking kind of deal). I also am looking forward to building it as a personal undertaking as I love remodeling/construction projects (I am actually documenting the whole process on youtube as I go). If I could find a small cabin ready to go for less than 100k, I would seriously have considered it.
@John Underwood you make a good point.
