I went in and adjusted assuming he's $20K behind on tax payments, it only increased his monthly payment by $333 per month since it stretches out along such a long timeline.
In this case, and moreso if he doesn't pay his 2019 taxes either, his payment will actually be a lot more to keep the condo. If he has basically not paid for 2018 yet he'll go from $2500 to $2000. If he hasn't paid for his 2019 taxes by the time he files for bankruptcy he'll go from $2000 to $1700.
If it reaches zero I believe he doesn't qualify but that's just based on my own logic and I don't know if that's really the way it works.
EDIT:
"So what happens if you only have enough “disposable income” to pay your secured and “priority” debts? What if there’s nothing left over for your “general unsecured” debts? You pay all you are required to pay each month and do so for as long are you are required to do so, but your secured and/or “priority” debts are so large compared to your “disposable income” that there is nothing at all left over for your “general unsecured” debts.
That’s called a “0% plan.” Your “general unsecured” debts get nothing out of the plan—0% of what you owe them."
"0% Plans Not Accepted Always or Everywhere
But there are also some situations where you aren’t allowed to pay nothing on your “general unsecured” debts. For example, if you are keeping an asset that does not fit within a property “exemption,” usually in return you are required to pay a certain minimum to your pool of “general unsecured” debts. There are other situations like that.
There are also some jurisdictions where the bankruptcy judges frown upon or simply do not allow 0% Chapter 13 plans. Your bankruptcy lawyer will tell you what limitations there are along these lines in your bankruptcy court."
In some jurisdictions you can pay nothing to your "general unsecured" creditors, if all your money goes to paying higher priority ones.
