I appreciate learning from others. 

Some new investors think of it as a no-money down deal and given those other costs, it really almost never is.

Sounds like you've been around the block in the RE space before, and I'd love to hear more about your journey chat about what kind of synergistic value we can bring each other.

The only other question I would suggest is that you do engage a property management company to review your quad and review your monthly financials.

Right of the get go that tells me many other people have looked at it and did not offer the asking price. 

Quote from @Chris Lo: Which platforms/websites do landlords use to find the rent rate, how long the rental properties have been on the market, and all the details about other rental properties?

They are trying to be halal but really just selling the loan just like any other bank.

I don't want to rent it out as it seems like an electrical liability - and I'm not sure if renting it to others would be legally possible seems how we don't own the land.

However, with the rates and conditions of any triplexes and fourplexes we could find (we did find one, but it's in the Pendleton Heights suburb of KCMO, so we were worried about it being too dangerous of an area), we were wondering if it's worth it to buy a duplex and rent out the other half to help pay the mortgage, or if it's more worthwhile to rent an apartment and try to save up to buy a residential or commercial MFH later?

My other concern is, in worst case scenario with an out-of-state CPA- if my tax return is audited and I decide to go to court, does my CPA need to fly to my state?
