They can be a bit of a pain since your have to have a licensed GC on the rehab and have to deal with some other process/compliance stuff, but they will be a conventional mortgage that can fund both the purchase and the rehab all at once (very similar to an FHA 203k).

IMO I think you need a physical book so you can earmark this stuff.

Not sure what happened (eg glass vase fell off a counter when jackhammering was done) or the value of the item, but the contractor said tenant's stuff should be fine and clearly it wasn't. 

All of the stuff he shares is already out there for free but usually when you pay for some sort of course, academy, seminar, etc...it's more about that information being all in one spot, organized, access to mentors, etc.  

Tenant is saying sections of the floor are popping up and stuff getting stuck between them.

Some stuff I’d likely be ok.

And the old adage is to get them in an LLC (LLC Series / which complicates leases and stuff) is not necessary. 

What is the best thing to do with all the stuff?

Check the utilities have been moved out of her name and if they have, she left the key, you have it in writing that she wanted to leave and all of her stuff is gone, then I'd say go in and start getting it ready for the next tenant.

I'm going to get some stuff from Goodwill and Walmart this week to dress up the room and put artwork on the wall.
