Lost on the conventional loan concept. 

Well, I built a couple am tables, and it looks like the interest and principal payments will be the same, whether you take over the loan with an UPB, or start a loan from scratch, assuming the same remaining term.What threw me off is the concept that Interest payments are a higher portion of the monthly payments earlier on, so I assumed that somehow this would harm a mature-note buyer.

I suggest that you read his article on the concept found here:How to "Hack" Your Housing and Get Paid to Live For Free"@Elizabeth Colegrove Thanks for the heads up - I definitely don't think I'm putting anything in that is over the top yet though!

Instructors also provide better clarification on hard to grasp concepts.

Personally I don't believe the concept of a total number 20-40 years can possibly predict what you will need. 

Hi guys,Actually im newbie at this field me and my partner have like 200k and thinking about starting buying some homes and selling it (our concept looks silly but we are here to try to learn more about that industry), we read the BP ultimate beginner book and searching now for some sort of feasibility studies in real estate, or any kind of numbers showing how much we need to invest and where and how much we should expect as ROI, the profit margin generally in real estate and costs accompanied, i know its general questions but if u can give us any kind of estimations it will be highly appreciated :)Thx 

Because I am new at this, concepts that may be simple and common to the experienced investor are quite complicated for me, so I decided to ask clarifying questions to aide my understanding.

After all, it isn't the concept...it all comes down to the plan.

Alternatively, do some here have success with the concept of the Deposit being a Promissory Note instead of cash (payable if/when closing)? 

The key isn't just to have on, the keys are to understand the difference between a plan and a concept, and then how to build it.You start by using reverse engineering, and with a need/opportunity.
