I think this is more your responsibility as her sibling not taking on the landlord/tenant issue.

As a preliminary matter, I wouldn't recommend owning property in joint tenancy with a sibling.

There are 3 siblings in my town that blended their construction businesses into one, as their accountant said it would have several benefits, one being with getting loans for houses (They build houses and 'house hack' them by living in them for about 3 years and then selling). 

However, my parents are now starting to think about passing their land down to their five children as well, and we all want to ensure it's done in the best way possible.Goals:Thankfully, my four siblings, my parents, and I all agree on the end goal of this farmland.

back story - my two siblings and I inherited a house in January 2013.

How did one sibling get the property and the other sibling get nada?  

Here is a copy and paste from the IRS publication involving prohibited transactions:"[NOTE: The term “disqualified person” under the Internal Revenue Code does not include siblings (brothers and sisters) or aunts, uncles and cousins of the IRA owner.]

The father was the builder and its now owned by 3 siblings of the second generation.It should be 100% depreciated.I don't know what the FMV was 9 years ago.So with the built in gains tax the rate is 35% on the entire thing for all 10 years, and then the next day it drops to capital gains rate of 15%?

@Bob MaleckiA sibling-in-law is absolutely not a disqualified party.  

The siblings would manage the house.
