Hey everyone, I am looking to get involved in a mastermind group in NY.

Both parties Signed, and everybody was happy. 

Yes that needs to be explained to all parties and can be handled in multiple ways.

Selling to buy new properties has a lot of costs involved with realtors, titles and capital gains taxes (variable depending where you live) so that should all factor into your opportunity cost ROI calculations.

No loans of any kind involved so activities such as the following one are definitely NOT possible for me: step 1: get a loan, step 2: buy a RE where i can be as sure as possible i will get people to rent it and pay the monthly rent fees (plus utility bill fees) matching in total at least monthly cost of loan, step 3: before fully paying off the loan, announcing (why?

In mine there is a set of usual and customary closing costs that each party is responsible for. 

Do you plan on continuing to pay your first mortgage if the HOA or another party takes ownership of your home via being the winning foreclosure auction bidder?

There may be a commission involved, but at least you'll have the right audience of buyers. 

Does Anyone have a good letter to send to the homeowner so a third party authorization form can be signed so I can do a payoff.. thanks all help will be appreciated

It gets a little involved and believe others may do it differently.
