Welcome relief from what is charged in the Houston area.

If it's only a year lease perhaps the least painful thing is to let her stay through her lease and then give her notice 60 days before the end of it that you have other plans for the property.RE marital status, FWIW, I sometimes misspeak and call my ex "my husband" 8 years after our divorce.

It all depends on your specific goals and risk / pain tolerance at this point of your life. 

Only leases of more than 12 months in my state require a notary, so the argument that it's not their signature wouldn't hold water and could be forensically disproved....But filling out two copies then and there by hand would be a pain.

I want to be sure my business is set up correctly to get the best tax relief possible.

This is a business and unless you want to learn some REALLY expensive and painful lessons you better start treating it like one (no judgement just tough love).

While it’s not rocket science, there are errors that you can make that’ll extend the pain longer than necessary.

It was a pain in my a** getting here but I made it!

One thing I’d add to the list is that utilities typically aren’t on which is risky + a major pain when you transfer title.  

We decided to give it a go, and since the biggest pain in the butt of a refi is all the paperwork, we decided to do 4 houses at once since the paperwork would be the same for 4 as for 1.1st one.
