@Justin Fraser Yes, it's disconcerting trying to get all the mechanics working, but it always (usually) seems to work out!

And as a newcomer to the country I would prefer to start with well-known and easy stuff.My advantage is diligence and honesty; I can admit my failures, learn on it and apologize if needed.

in the same link you posted...the lien shall be valid against any purchaser, holder of a security interest, mechanic’s lienor or judgment lien creditor, except with respect to properties or transactions specified in subsection (b), (c), or (d) ofsection 6323 of the Internal Revenue Code of 1986 for which a notice of tax lien properly filed on the same date would not be valid.

I'd like to do this while creating and maintaining multiple "safety nets" to avoid failure as much as possible.

We make enough money to be fine with kids but it made me remember that I want to be more than fine and I want my kids to be able to learn from my success rather than failure or mediocrity.  

Both my mentor and our mutual real estate attorney both strongly recommended filing a mechanics lien at time of closing. 

I have  my " why" so as far as I am concerned failure is NOT an option for personal reasons that motivate me so I shall prevail.

Jumping into a five property deal fresh out the gates is setting you up for failure.  

I just picked up my batch of returned postcards and I definitely don't look at them as failures in dead leads.

If you read my profile you will see that failure is something I do not wish to experience.
