Buying rental property as 2nd home to pay 10% down (3+ times!)

[David Samuelson]

I recently bought an investment property with a vacation property loan, 4% 30 year fixed with 10% down.  My broker couldn't get me a 2nd vacation property loan, so I found a new broker who was willing to get me another vacation property loan, I just had to write a letter stating the other property was converted to an investment property and was no longer a vacation property. So I then purchased my second investment property, again, with a vacation property loan, 3.625% 30 year fixed with 10% down.  Now my new (2nd) broker can't do another vacation property loan. 

Question.  What if I just use another broker.  Technically, my other properties are no longer vacation properties, they're 100% investment properties, so I should be able to purchase a new vacation property.

Other then lying about the intent of use for my vacation properties, is there anything illegal with this strategy?  All my friends have turned their vacation properties into short-term rentals so it seems this is a pretty common thing.
