But the husband has children from a previous marriage, the children is not named in the Will but I was told they have to sign the proper paper work before the house can be sold.

I have customized the customer fields to be more LLL specific -- like tracking the names and ages of the tenant's children and the license plates and makes and models of tenant cars. 

However, if they ever added another person to the LLC (one of their children or another relative), they would lose the exclusion, since it would then be taxed as a partnership.

But have to be by the heirs, as well as one or 2 people, who knew the family and can confirm that there aren't any additional children.

I ask because I have an application that I will in all likelihood be denying as they have 6 children (2 adult) that applying to live in my 1600sqft 3/2 SFH. 

I don't have any children to leave property to so not sure how a trust will help me, as I want to have control in case I decide to sell in the future......

Especially if the tenants have children.

The third option I imagine is building a completely separate Trust just for the rental property, place the LLC as the beneficiary, along with her children.

This family has four children whereas the previous tenant had none, so it's pretty clear who caused the issue.My lease is clear:Owner will not pay to repair conditions caused by the Tenant, his guest or invitee or damage due to windows or doors left open, sewer/septic stoppages caused by foreign or improper objects in lines, or cosmetic items that do not impact the functionality or use of the item.

Historically, people allowed the home their tenants were living in to get foreclosed on before they let the home where their own children sleep at night get foreclosed on.
