(As an aside, there is an interesting over funded insurance product that you borrow from for the rest of your life to attain tax free income.) 

Long term fixed rate loans pose less risks than short term floating or balloon products. 

Going into an offer thinking "I don't know why she would want to" isn't going to be productive.

This listing sounds like an non-financeable investment property in which case it should be selling to a sophisticated crowd which requires minimal handholding.Also as a new agent I’m curious on what sophisticated mechanisms you have to sell houses with alacrity for exigencies?

@Mark Cohen there are not insurance products that will insure against an under performing business operation. 

If you've structured the deal in such a way that allows you to have a good amount of equity in the property within a reasonable timeframe, then a good option may be conventional products like the FHA loan.

If you know someone who offers that product, please raise your hand.

It's unclear from the question whether the home you already own has a vacation home loan as well.IE if home A is an investment property, then you can buy home B as a vacation home.If home A is a vacation home, then you cannot buy home B as a vacation home.If home A is a vacation home and you're desperate to buy home B as a vacation home, I would think you could refinance home A into a different loan product, and then the vacation home loan would be eligible for that area again. 

I set up a Service in Products and Services and linked it to the Income Account "Billable Expense Income" (BEI).

When getting a mortgage, there are several more highly leveraged (low down payment / equity) loan products for owner occupied property.
