I have many tax lien certificates to record, but have not reached the 90 day mark yet.

Has anyone here gone through the process of purchasing tax lien certificates in NJ?

I read every book I could find on both tax liens and note investing (there aren't that many) and was lucky enough to find a local fellow note investor and pick his brain.For tax liens I read: The 16% solution : how to get high interest rates in a low interest world with tax lien certificates by Joel Moskowitz The complete guide to investing in real estate tax liens and deeds : how to earn high rates of return--safely by Alan NorthcottTax Lien$ by Michael Pellegrino (This is specifically about New Jersey tax liens)I also learned a lot from Joanne Musa (the tax lien lady) on youtube and through her website.For notes I read:Performance Anxiety: Creating A Fortune Investing In Non-Performing Real Estate Loans by Gordon MossInvest in Debt: The How To Book on Buying Paper for Cash Flow by Jim Napier (available to read for free on openlibrary.org)Note Professor Notebook by Tom HendersonAgain there's a lot of great material on youtube.

@Mindy Jensen  I wouldn't consider buying without an estoppel certificate. 

You can also do title certification which is a 60 to 90 day process and it can only be insured my one title company - first American title.

Make sure that you follow the law and get certification from their medical provider, however if the animal is legitimately certified you cannot discriminate against the tenant even if you have a no pet policy, otherwise it would be a violation of ADA (Americans with Disabilities Act).

Check to see if your state has the second provision, in which case, you can request a per pet evaluation done by a professional (if your state also clarify who can actually provide this kind of certificate). 

I have my payroll certification so I guess I could do some HR work for small businesses...I actually never thought about that so thanks for the suggestion! 

however, if you have access to the Elevation Certificate (the current owner or some Cities have them on file), you can look at the measurements listed there. 

Hello Starting Out-Lots to unpack with your question, so I will only hit the some of the bigger items.Investing in tax lien certificates as a method of foreclosing on the property is not a valid strategy in my opinion.
