Rules and laws to keep in mind when house hacking?

[Sebastian Hernandez]

Hello BP community! 

I am new to Real Estate investing, at the moment I am learning, absorbing knowledge and exploring different investing paths. I have been particularly interested in Househacking. 

I hope to an agent recently and he did not seem too thrilled with househacking, he advised I could lose the home if the lenders found out I was renting the home or most of the home. 

How true is this? how are investors getting through these rules? any other rules/laws to keep in mind?

Thank you BP community!!
