Primary vs. Rental Property?

[Chris Mylan]

Hello All,

I am very close to buying a property in Pittsburgh, Pa and wish to have it considered as my primary residence and rent out the other rooms. I rent an apartment and work in Washington, DC, but take very frequent trips back to Pittsburgh (holidays, every other weekend I spend 3 days there, medical leave, etc.)  and also am allowed to work remotely through a work agreement. Can this Pittsburgh property be my primary residence or will I have to file it as a rental property? I spoke with the lender and they are confident I can file this as a primary residence (great because I can put down 5% instead of 20%). I just need to give them proof that I am allowed to work remotely through a "telework" agreement, which I have through my employer. Legally, does this sound correct or will I be committing mortgage fraud? Is the lender I'm working with misleading me?

Really appreciate any responses and expertise!
