Of course, your friend needs to step back and ask what are they trying to salvage.

She then was told she has 24 hours to remove all the belongings on the front yard- or I will throw everything out in a dumpster.

Get a sign in the yard once the outside looks good to draw interest, this way when you are ready to rent or sell you have a list of people interested in the home before you have to let it sit empty for a long period of time.

There are many reasons these days how someone can land on that list, but who I would not necessarily think of as a risk:He may have slept with his 17 year old girlfriend, when he was 18.He may have been drunk and peed in someone's front yard and their child saw it.He could have been with a prostitute who was underage, but didn't look it or say itI have a sex offender living in one of my properties.

*Older homes that are in disrepair, find someone to salvage them for free and get them out of your park (unless there are GREAT paying tenants in them that want to stay in them).  

She has seven ash trees in her yard.

I have always done a lot of the work around my house - plumbing, carpentry, electrical, painting, and yard work - and am not afraid to try to fix an appliance when necessary.  

What are you trying to salvage - the house, their equity, their personal possessions, something else?

This had more and less been a hoarder house and had been vacant for 15 years.The one bath was not in great shape...There was a garage with an apartment in the back yard that was rotting to the ground, neighbors complained of rats coming out of it and tree's had grown through the roof in multiple places. 

i've always done the exact amount on the POF letter. esp if you're trying to get a lower price, not the asking price. it's like offering someone $2 for something at a yard sale and then asking for change for a $20. just bad bargaining etiquette in my opinion.
