Account ClosedBigger pockets provides great resources in their "tools" section, I think there is a document titled "Promissory note"You can also talk to any lawyer or a simple google search would do.More than the note, however, it is important that the two parties (lender and borrower) trust each other and live up to their commitments.  

You have to use the website from the computer and then you can use the analyzer by going under the tools tab.

Portfolio loans really are a great tool and I see them work frequently for investors, I just want to make sure you have a decent perspective.  

I'll call this bit:Being thankful for small favorsSo using tools here at Bigger Pockets I wrote up a scope of work.

Things like:- who directs the work- are there contracts in place for the work- how are the contractors paid (it is generally better to pay them on a job basis and from an invoice they present)- who provides the tools- do they have their own insurance- do they advertise- do they work for othersThose are just some of the tests that could be used. 

I am considering asking the seller's agent to become a transaction broker on the deals I am considering to use as a purchase negotiating tool, e.g. offer less since seller does not have to pay a commission to the buyers agent. 

I'm looking for something like Pipeline or a CRM, but one that is Real Estate specific or allows connections to Property Radar and things like that.

You will see they are investing in the strongest markets, have great broker networks / access to deals which is critical in a highly competitive market, can raise significant capital to take advantage of scale, more disciplined / conservative underwriting models, have simple well thought out business plans to increase the properties value, using fixed rate 10yr loans to take advantage of still incredibly low rates historically speaking and use more sophisticated tool sets to help understand how fluctuations in occupancy, rents, etc may impact their models.
