By the post, it sounds like they have increased their demands (noting it is now a different party).  

The other part is principal on the loan you're repaying. 

I was told to use 8.5 x 11 sized paper and a small envelope like the type used for a party invitation.

There is a couple of ways that this can benefit both parties:1.

hi jay. i live in west seneca and i am a home inspector and real estate investor. i would be glad to help you out. i have done some wholesaling. for the most part, i flip them. let me know what you need. 

Seasoned note investors are usually the one's buying these because you have to have third party vendors who can verify property values (real BPO's not just online), attorneys in the state's where you acquire the NPN's ready to foreclose or modify the loan, verify that the note is transferred correctly, notify you of other liens, make sure the note was drawn up correctly and that if it has previously been transferred the transfer was handled correctly.  

The only part i believe it hurts is if you are wholesaling other than that.

I just wonder if Sixty Minutes happened to mention the fact that these areas of blight have voted almost without exception for the same party for decades?  

It would definitely help to know what I should be mindful and respectful of when approaching an agent about being a buyers rep.2) If we were working together as agent and investor, what sort of interaction and milestones would keep you interested in a continued relationship where both parties are receiving benefit, and on the flip side... what would make you want to walk away?

You might want to have an outside accountant or a qualified third party (escrow if possible) disburse funds.
