Wow, she's going to kick out two paying tenants without so much as a blink of an eye.Well, for one thing they didn't ask the landlord's permission and they brought in a dog. 

Be sure to get the sellers permission before doing any phase 1 or 2 work and make sure the permission letter to perform environmental testing doesn't obligate you into a purchase agreement.

The only way to get access to a foreclosure is with the permission of the occupant.

Should we plan on having them evicted (they never had leases, just month to month) or first ask the tenants for permission to allow the contractors to enter on a certain date and try to schedule the bathroom remodels at different times so they still have one bathroom to use?

I think they're unnecessary but it depends on your area.Definitely talk to the tenants and get their permission before installing anything.

The few assumable mortgages out there are only assumable with the permission of the lender.  

Check your state laws to see what is permissable. 

So many of the IRS regs involve you begging forgiveness rather than asking permission! 

You complicate his foreclosure if it comes to that, and you keep him tied down longer than he probable expected (say 8-9 of those 10 years instead of a usual 4-5 years).On the other hand, a second mortgage would be subordinate to him, so why do you need his permission?

My lease states that if someone additional lives in the property for more than 48 hrs, the tenant must get written permission from the landlord.
