I see the musical instrument in your photo, related to Herb?

I've read most of the "religious" books and have yet to see an example of an Angelic Vision arriving to fix Vapor Paper.Tighten the hatch-bolts - I believe I hear the dive siren blaring in the near distance.I'd suggest Mr.

If you decide to rent to her, be prepared to be subpoenaed by the IRS when her tax fraud case goes to trial.

I'd advise her that she should limit her answers to refer to you as your representing the property for her..She's paying you to do the job and there is no reason not to let her be there.As a buyer I would think it's a plus for owner to be there for showing / walk thru.

Maybe you can try letting her being your agent as well as the buyers agent.

If condensation has built up under the plastic your basement is not currently sealed and you'll have moisture problems you'll want to address (tiles, vapor barriers,sumps).

If the tenant was unaware that the property was being offered for sale, I would consider her being the bearer of that news to be a significant breach of the ethics of our business. 

Ive also had sewer backups because of tree roots in the main sewer line from the home, and that     was not a pretty picture.I also asked my wife about this, her being an insurance agent, and she said most of her Insurance carriers would require this tree to be cut down before they would insure the home.

I had a tenant once that left her entire Wiccan spell kit herb/spice kit behind, complete with directions.
