You'll need to look into your state laws, but practically speaking it's pretty simple.

Nor are they properly under the control of the person bringing it.

With all that said, we have thought at some point we might take control of it and manage it ourselves. 

For my units I use the (to be phased out on vacancy) rental control ordinance in my town as a guide.

If they bring a pet, tell them the pet needs to be gone the next day or you will call animal control for a stray pet on the property.

After all, if they let it go to a tax sale, they still control the property for another year (due to the aforementioned redemption rights).Consider why properties end up being sold at the tax sale.  

Since the term of a lease has little to no relation to how long a tenant stays M2M is the same as a term except the landlord has greater control.

Internet leads are practically worthless.

If yours is in the middle ground between those two they might accept it if you agree to a last-minute 1% rate/point hike.I stopped working with and offering true hard money some time ago because I don't like working for free, nor do I like having to be the 'voice' of the bait and switch without having any control over that.

Stop digging yourself deeper, hit the reset and sell while you still some control and options.
