(Jack it up and then replace them or nail a board on either side to support it if you can't replace).

@Chris Grenzig IRR is not easy to explain but you nailed it on the head! 

Sherman Ragland just hit the nail on the head.

They don't ensure all the nails are up on a demo, the paint scrapings will be there for years to come in the bushes and landscaping.

Run some comps, make a call, nails hammered.

I stop myself and realize how ridiculous this is, can't nail every deal perfectly.Anyone else beat themselves up unnecessarily?

Starting off can be difficult and you hit it on the nail.

The floor squeaking could be from nails used vs screws but its a 100 yr old home so this will happen. 

sorry about the delayed respose. you nailed it Colleen F., it is a property management company so these cosigners are very common here.I emailed her and talked to her on the phone, she was very nice and explained that she wasn't going to evict us out of the blue like that, but the somewhat threatening email was just to get a quick response.A false alarm altogether, I think I mostly wanted to know if she even had the legal grounds to kick us out on a whim like that.Thanks for all the replies, I did learn a lot from all of this. :)
