Then dropped her like a sack of potatoes when he found someone younger.I almost had to evict her to but to hush me up, he came to the rescue and paid in full including all my late fees.Public figures are the shadiest!

So, I'm not sure what the "multi multi million dollar properties" have to do with the rest of us.If you want to talk about the "meat and potatoes" RE market, I'll bet you'll see some palpable downward pressure once the rates come off their historic lows. 

I echo the above advice to make only the minimum basic repairs: fix the leaks, get rid of the mold, clean it up, stabilize it so water intrusion and whatever issues it has aren't getting worse, maybe do some demo to get rid of major eye-sore areas, slap some paint around strategically, remove trash/overgrown bushes and whatever from the property, improve the curb appeal however possible, apply turd polish liberally... whatever you can do with as little money as possible to make it look a little better, and then wholetail it like a hot potato for whatever you can get. 

They consider it small potatoes compared to the “bigger prize” of listing and sales commissions. 

I had one tenant sue for deposit herself, but she sued me and not my management company for some reason, so I self represented and mopped the courtroom floor, counter sued, and won in less than 2 minutes of the judge hearing the case.The overall amount for all cases combined was less than 3k, which is potatoes!

In a transaction everyone fights to CYA and pass the potato in case something goes wrong down the line.I have also in addition to these comfort letters seen the lenders ask attorneys for bankruptcy opinion letters.

The leaders in the space work with 80K - 120K clients and hold around $8-12B in assets, so they are not small potatoes.

A big mistake is getting caught with a hot potato you can't sell and or afford.

It's a great way to learn through osmosis.
