Redemption PeriodThe defaulting taxpayer, any grantee from the owner, or any mortgage or judgement creditor may redeem each item of real estate within twelve months from the date of the delinquent tax sale.

Aside from offering this as a benefit to outstanding tenant prospects.So, you think a GOOD tenant will break a lease and accept a judgement against them that may follow them as a lien, gaining interest all along, and nixing their hopes of buying a home for years unless eventually paid off?

Am I correct in that or do I need to go to court and get a judgement first?

Also find out how to file a judgement for outstanding rent-you'll likely never see the money, but if you can get it attached to his credit score, that would be good.

Gerry are you saying you actually brought legal action and was awarded a money judgement ?? 

If he owes you more than was awarded in the judgement, have a buddy serve him with a small claim summons on his way out. 

I have evicted a tenant got a judgement from the court.

They only have a simple promissory note that they likely now have to file a lawsuit to win a judgement, with again no promise of repayment. 

If you have a lot of equity that is an asset that can be taken to pay a judgement.

If it is the tenant, then you may not need to pay the bill as it wasn't in your name.After that, you can try small claims court, but even if you get a judgement, you are unlikely to ever see the money.
