And I'm like: "No problem, would you like a paddock for your unicorn and a personal rain cloud for your large money tree in the backyard too?"

Since you specialize in multi-family, I know you are no stranger to the rain in that aspect. 

Told him to not let it rain, even though a huge rain storm was coming at me, and I had to work the next day.

If it doesn't feel right, trust your judgement and move on.

Pre-foreclosure property, judgement balance of $155K, ARV was $220k (best case). 

I would give them a 60 day notice but use your attorney's best judgement.

I'm sure there will be - as usual - a string of naysayers and chicken littles who will now rain down upon this post. 

I'd have half a month's rent (in sec dep) and only 15 days notice to evict the person and repair the unit.In Philly PA, the owner usually gets 3 months upfront - 1st, last and security deposit, so there's more flexibility.It's probably also different if you have the tools to take people to court to garnish wages for unpaid rent and damage judgements.

Scenario: 2nd lien bank foreclosure auction ~ $50k judgement/fee/interests. 

I know none of my stories are not as bad as some people's and I am not trying to pass any kind of judgement on single mothers.
