@Josh Ball mentions, there are issues with foreign investors but, nowadays, it's not necessarily on the tax front anymore.

I am interested in utilizing space again for group meetings, workshops, and for clients who may still desire private space.

You could structure the deal as an installment sale or a lease option so the property owner doesn't see a large capital gain tax payment for the sale.And good on you for helping out!

Most likely raising funds from passive investors would utilize a Reg D 506 b or c safe harbor exemption from registration.  

If you sell it, you get $250k single / $500k married exemptions from capital gains.Speak with a tax professional about how much you'll save in taxes by doing this. 

This property is gonna cash flow over $1000 a month after we're all said and done with utilities mortgage and more.

While you rent the other side of the duplex out.Voila - No tax paid. 

I did make sure they got the utilities switched over in to their name which took a few days.All in all, it was maybe 7-10 days left in august by the time they got all the utilities switched etc.

How much do the utility hookups cost?

@Dalton Foote I have had tremendous success using direct mail and mailing the owner of record where the tax bills get mailed to.Generally, property management companies don’t pay the real estate taxes so this gets me right to the owner.Targeting wise, I would just do a zip code filtered by unit count using a service like listsource.
