The action of bringing a buyer and seller together in exchange for consideration is Brokering real estate.

I run a large group of independent landlords and we share lots of stories and info exchanges about working with contractors.

A 1031 exchange is for a "like kind" exchange. 

You will be well served to learn about the withholdings that will take place if you ever wish to sell or exchange the real estate you buy here.

You an use a 1031 exchange on the portion allocated to the investment side.  

anyone have any experience with investment property loan exchange

You'd need about 250-300k for a down payment for a starter duplex which may work better for you since you can utilize one side as a long term rental and the second side as an STR which you can use as you please but remember if you do a 1031 exchange you'd be limited on how much you can actually use that property to still be considered an investment and not a second home.

My husband did a reverse 1031 exchange on a property over 20 years ago. 

Can anyone recommend a reputable 1031 Exchange Company?
