His attorney should ask the court for a freeze on the proceeds of the sale subject to a lawsuit.   

@Greg H...I know no garnishment,but I can freeze his bank account or something right?

Setting the hype aside (and there is a lot of hype) Dodd-Frank Act of 2010 has the following provision:"While the act is meant to protect businesses that “stimulate the economy” or are “too big to fail,” thanks to the loopholes in the verbiage, if you happen to hold your money in a savings or checking account at a bank, and that bank collapses, it can legally freeze and confiscate your funds for purposes of maintaining its solvency.

I also have to deal with winter issues and calling my PM to winterize a vacant house so the pipes don't freeze and burst.

Not familiar with your location, here in freezing country, pipes don't go underground after the meter...

Is there a percentage that you set aside or am I overly concerned about the effect the freezing temps have on rentals?

No pinhole leaks, cracks from expansion, or long wait times for glue to cure in freezing temperatures.

If you still have problems in the cold, your Beam may be freezing. 

Midway through a project, lender can freeze, revoke or lower a line if timely payments are not being received when due on drawn funds.

As long as credit does not freeze there is always going to be some velocity in the market.
