Financing An Off-Grid Cabin Build (Building Myself)

[Harrison Glaude]

Good morning! This is my very first contribution to BiggerPockets, and I am excited to be a part of this community. 

I recently purchased a 5 acre off-grid tract of land in Hoenwald, TN (1:45 outside of Nashville). I have been clearing land and getting ready for well, septic, solar setup, and build. I am at the part where I am looking at financing options but I am at a bit of a crossroads. 

1. I am building this cabin myself

2. On top of my living expenses I have roughly $1k/month extra I can put towards a monthly payment in a loan. I have been trying to figure out if it is possible to refinance a completed off-grid cabin that has a high-interest hard money loan of sorts into a 30 year mortgage to drop monthly payment and increase cash flow once rented out. 

Any advice from someone that has gone through this or knows about the topic would be GREATLY appreciated! Thanks in advance!
