My RE agent said it will not be possible but I have seen people mentioning this on the forum.

Occasionally, I'm asked about two or more people pooling their resources to buy properties.

People told me I could hire someone to help setup QB for my rentals but this would have cost a couple grand.

The best way, in my opinion, to get into real estate is through a house hack as I'm sure you've heard a lot of people say.

Too many people sign up for a coach thinking it will make their growth easy.

I have made a post on BP before and some people have suggested a DSCR loan.

So you're asking the wrong people. 

Yes, you can sell it.Sometimes Peoria will grandfather a duplex and refer to it as a "legal nonconforming" single family zoned property with duplex as permitted use.If this is the case the new owner will be able to legally and officially use it as a duplex.I have also heard of people finding an architect to declare that the house was originally built as a duplex, which would help you get it rezoned as multi-family and duplex as permitted use.PM me for more info.
