The seller was willing to loan me 30% on the second leg of the transaction or $210,000- Paid off my transactional lender of $140,000 and pocketed the difference.  

Hey @Wei Jie Yang - you should start by reaching out to the lender that currently holds your mortgage and work your way from there. 

Hello everyone,I am starting with little to no knowledge about being a lender and a broker for private investing. 

Partly due to the lender failing on some stuff, firing their processor and having to redo a lot of things last minute.

@Brian Plajer - while this offer may sound very helpful, it is a blatant violation of BiggerPockets rules against self-promotion that specifically PROHIBIT offering services to investors, publicly or privately. 

But if not BankofAmer, would another mortgage lender take on the 2 mortgages and blend the interest rates together based on my credit and possibly even cash flow?

Talk to some lenders about HELOC opportunities.

You're basically asking for an unsecured line of credit, which you'd only get if you have an established business with a strong balance sheet in the US (and you already do business with the lender).Add 1 and 2 and it sounds like mission impossible to me.

Some of the folks who answered your question are good PMC just talk to them privately and they will answer your question.
