i just didnt want my customers thinking we were trying to slip something past them.

A quick Internet search of "Costa Rica Mortgage Loans" turned up a couple of brokers and private equity offerings.You could also try to get the seller to finance part of the purchase price.Or borrow it from your 401K, if you have one.Depending on your credit score, it might also be worth looking at rates from a local credit union, bank, or even Prosper or Lending Club for a personal loan rather than a real-estate secured loan.

Also, in general, would an appraiser likely aim to provide favorable results to keep you as a repeat customer?

You are probably a "customer" which means they don't represent your best interests and have no requirement to protect you, negotiate on your behalf, etc.

You have to find the Direct Seller and don't deal with Brokers His course it worth the money and his seminars are even better.

The only explanation from their customer service folks was that it "couldn't be used for that type of transaction."

Longhorn has been doing 100% financing for 16 years with 8000+ closed loans and has a stellar reputation and many, many repeat customers.

Broker will pay 2.5% of/from the sale price. 

Anyone know quality, custom cabinet companies in the area for a good price?

I am looking to partner with a reliable loan broker for both commercial and residential loans
