I have a home owner requesting $94-139k HEI loan, structured to pay the loan when the house is sold, in 10 yrs. 

Finally, start hitting some meetups if you can to pick people's brains, find potential deals, learn what about areas you don't know, etc.Best of luck!

When you say Broker are you referring to the real estate agent or a loan broker?

Not just a lender who can put together a loan document (they all can do that), but someone who is interested in your goals and can advise you in different strategies, downpayment assistance programs, etc that can get you going.From there your financial strategy and the local market will begin to steer you in a direction of homes available and that fit your finances.

They should be able to refer you a lender that can walk you through ways to limit your cash to close.For your specific questions, an FHA loan is probably going to be your best bet.

Commercial loans are larger sales prices.

That is an Investment Rental Portfolio loan.

So, if I am putting down say 20 percent on a new loan for a vacation rental, my realistic goal should be "Let other people pay off the rest of my investment for me."

Will they allow a loan assumption as the new deed owner?

How loan officiers can pay Referral Fee to realtors in a legal way, and NOT as kick back?
