I am 24 years old and I am a Dental Assistant.

Can I start procedures to remove them?

All:I'm considering making an offer on a commercial building that is leased to a dental office and would love some advice on how to structure. 

So for her the 1031 is a very doable procedure to defer the tax on that $500K gain (plus probably a bunch of depreciation recapture). 

Good Location, A lot of Redevelopment, Great Numbers, Fair Eviction Procedures.

To mitigate in the future ask for a conditional waiver together with his invoice before you issue a check, and unconditional waiver together with your transmittal receipt with (guarantee that he paid all subs and suppliers) of the check.For him not to put a lien, call his contractor's bond company, let them know that the contractor abandoned the project and you would like to file a complaint and want to know their procedures.

@David GreeneI also want to applaud you for writing a book on OOS investing and sharing your procedures and best practices.

You don't say where you're located and the procedures for these auctions vary widely.

I'm getting myself educated with the procedure and will be seeking some help from the old-timers that do this in a different area.

How do I go about this procedure?
