While we've attempted to show good will and provide reasonable accommodations, our tenant has unrealistic expectations in more ways than one.

@Stephen Wilson, as far as the 1031 and need for cash that can be accommodated  very easily. 

To say that we are busy is an understatement.Me personally, I accommodate my clients where possible and will bend over backwards to get the job done if it is time sensitive, but if it's not a priority and can be handled after April 15th, that's the route I suggest."

And how should i accommodate their recovery (I currently live in the upstairs unit)Thanks

The second breach of lease in the 12-month period you have the option to serve a 5-day curable notice or a 14-day non-curable notice stating they have to move out.On a lease greater than 12-months, you need to provide a 30-day notice to pay or quit, and if memory serves me correctly, you have to do this every time rather than being able to serve the 14-day on the second failure to pay as stated above.If you are using the Wisconsin Legal Blank lease, you will need to add language manually to accommodate for the ability to serve 5-day notices on leases greater than 12-months. 

I found this article that links to the new HUD guidelines on Reasonable Accommodations For Assistance Animals, including Service animals, and emotional support animals. the actual guidance does not change any current laws, but it does help to clarify and provide some best practices for us as landlords and tenants seeking to request  reasonable accommodations. https://www.forbes.com/sites/brendarichardson/2020/01/28/hud-issues-new-guidance-on-reasonable-accommodations-for-assistance-animals/#3a4bf8c26531And the actual guidance is below https://www.hud.gov/sites/dfiles/PA/documents/HUDAsstAnimalNC1-28-2020.pdf

t=52 it says you won't be able to rent to your son and his family.In the bill it says "§ 214 (G) THE LANDLORD SEEKS IN GOOD FAITH TO RECOVER POSSESSION OF A HOUSING ACCOMMODATION LOCATED IN A BUILDING CONTAINING FEWER THAN TWELVE UNITS BECAUSE OF IMMEDIATE AND COMPELLING NECESSITY FOR HIS OR HER OWN PERSONAL USE AND OCCUPANCY AS HIS OR HER PRINCIPAL RESIDENCE, OR THE PERSONAL USE AND OCCUPANCY AS PRINCIPAL RESIDENCE OF HIS OR HER SPOUSE, PARENT, CHILD, STEPCHILD, FATHER-IN-LAW OR MOTHER-IN-LAW, WHEN NO OTHER SUITABLE HOUSING ACCOMMODATION IN SUCH BUILDING IS AVAILABLE.

In addition to having nice, clean properties; it's a pleasure to provide pleasant accommodation for good tenants!

That way, when a deployment comes out of the blue (like it did when I was 4 months pregnant, stationed away from fam&friends still working fulltime and alone with our 2 yr old), I already know what's ahead and can accommodate as events get closer.

Doing so will show the court you made efforts to accommodate to the tenant if you later decide to evict.
