Hi dbrady01
I have indeed first hand experience of log homes - I built/live in one. I am also a mortgage broker by the way. There are a number of lenders who will finance - but the bigger problems arise in relation to fire insurance and engineers. If you wish to pm me, i can give you some contact names in a couple of the banks, and in the fire insurance area.
As an aside, and speaking from bitter experience, be sure that your engineer/architect is 100% comfortable with the method of construction. Ours had some large mental leaps in terms of materials, and at the end of the day, the engineer has to sign off on the house and confirm to a bank that its subject to planning and building regulations.
