Now i'm trying to negotiate with Ditech to pay them less for the redemption certificate that they bought at sheriff's sale.Has anybody tried doing it before?

Have them fill out a W-9 form, always pay with a check, and if total payments paid to them during the year are $600* or more, then filing a 1099 is appropriate.Also, you should get them to add you as an additional insured (or at least a certificate holder) and have their agent send a copy of their insurance to you directly.  

Concerning average number per state, what are the top states for buying tax lien certificates?

6.What is your certificate of abandonment, and how do you get one?

Be sure you do a Title Search and obtain  MLC Municipal Lien Certificate. 

My interest in real estate stems from a desire to begin delving into Tax Lien Certificates/Tax Deeds to eventually by and hold income properties. 

My concerns are that even if we are going to deal with it, and have a certification from a mold remediator, if the problem returned, I can find myself deal with a "mold is gold" lawyer.What do you think?

We had to sign a certification that we would owner occupy for a year. 

On my Certificate of Disbursements the money went to the foreclosed and this is the one with the assignment. and the one that said satisfied is the bank that i see as the second "upon that certain property situated in said state and County Herby acknowledges full payment and satisfaction of said mortgage, and surrenders the same as canceled ,and herby directs the clerk of the Circuit Court to cancel the same of record .maybe just to take it of record ?

The MLS listing indicates it is a legal 3 family, but yes I'll be sure to make sure I ask for that certificate.
