My farm can be broken into 25 lots at with a deep well and Fort Hall irrigation I imagine that if a person builds top quality homes you would stand to make millions, so just don’t look at Boise area for investing, not with what is happening in Bannock County.

If you want to give material upgrades away fine.

I am no self-proclaimed expert on economics or real estate; however, I do own several paid-for rentals, and I am considering the idea of turning my current paid-for residence into another rental, moving into a new personal home upgrade.

No idea how much they charge to upgrade from standard to "preferred".

I also just recently upgraded to Pro and want to take advantage of all this great site has to offer in hopes of getting my RE investment activities moving at warp speed.
