Some people pass on so many deals by the time they pull the trigger the market has changed and they missed out.Legally if a realtor is involved they are not allowed to use the multiple offer situation unless there are really mutliple offers but they also do not have to disclose anything to you. 

Within five years, it had helped trigger a complete breakdown of civil order and the city's population began to rapidly decline.On July 23, 1967, police attempted to break up a notorious "blind pig" in the heart of the new Model City.

Part of the challenge now is just pulling the trigger.  

which got triggered and you had the police kick them out within 48hrs, does it qualify as squatting?

I am just a little nervous on pulling the trigger on my first Tax Lien investment and am looking for some guidance from wiser more experienced investors!

I pulled the trigger. 

The three year rule applies to a lease, any lease term less than three years will not trigger the due on sale clause.

Well I have finally pulled the trigger and am currently completing the process of purchasing 2 fourplexes from a bank!
