They're trying to get STR prices with their midterm so they're priced ridiculously high and, subsequently, aren't getting rented.

I had a question about the equity in the subsequent properties to be purchased.  

So if you are owed $23.4 on a $130 lien (18%), and someone pays $300 for it, then they are happy with an 8% return (23.4/300).I know NJ also has unique rules around the winner in certain circumstances getting the right to collect interest on subsequent tax payments without having to go to auction.

Tax lien investors will sacrifice not earning any interest on the front end but make it back on subsequent tax liens.

If you're concerned about leaking and subsequent mold issues from a leaky roof, I'd highly recommend you get someone to inspect it.

My experience has been that price gets reset each year to the sale price and then subsequent years are much more subjective based on local markets and permitted improvements.

Do you have a tool or method to determine if the expired has subsequently been relisted or not? 

Begin building your network while subsequently learning the industry.

In regards the stock market, leverage leads to market froth and subsequent crash and I believe it is now illegal. 

If you were to subsequently cash out the new four for 4 more, you'd still only be 70% leveraged.So I vote for option 1.
