Anyone can go on line and get a "certificate" for $65.

They can do it in less than an hour and supply you with a certificate once complete. 

I wanted to see: My rental address The date I purchased this propertyWhat type of dwelling it isThe year it was builtHow much I paid for itHow many square feetWhat I sold it for when and if I sell itWhen I received my Certificate of AcceptanceWhen I received my Certificate of OccupancyWhat would you like to see on your form?

I was wondering is there certification that would help me diverse myself from others or is that done mostly by your reputation, recent work done and such. 

He showed me a copy of the certificate which says he bought it for price of back taxes from city two years ago.  

Buy the building in the  name of the LLC and allow your investors to purchase membership certificates.  

In my head I called it 'municipal lien certificate' instead of cml

Unless your local regulations specifically require some type of mold certification or license in residential (which I highly doubt), you will end up paying excessively for something you can do yourself.

if you are really ambitious and assuming that you took out at least $500 dollars, use the $500 to purchase a CD, that’s a certificate of deposit, not the new Maroon 5 CD.

I've been reading up on tax lien sales and just curious -- how competitive is the bidding for tax lien certificates?
