Let them pay when they have the funds rather than gambling that they will still have it when due.  

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.

Talked to both of the next door neighbors and apparently this lady (with kids 😮‍💨🤯) broke in and set up house only two months ago.

Hello ladies and gentlemen of BP, I'm Billy. 

My name is Brandon, and the lovely lady in my photo is my beautiful bride Heather.

In 1999, there's this lady that rents big-size houses in Milpitas, San Jose ,etc...perhaps total 20 houses.

@Brad Clarke and anybody else looking for info - I'm happy to share anything I've learned on both of these journeys so we can all make the most informed gambles possible.

Behave ethically, don't put any old ladies out on the street and just try and solve people's problems.

Attempting to time the market is a risky gamble that often leads to missed opportunities.

Usually about half the people don't come and no one comes on time, but it does stagger people so they are not all there at once.However, I DID HAVE ONE LADY GET VERY CRAZY!
