Probably because ADUs are ugly garage conversions or the property is undesirable or overvalued to begin with. 

There are enough turnkey providers that contribute on BP, I'm sure they would have a conversation with you.

I am looking to do some conversions from SFH to duplex on a couple properties and build relationships for future BRRRR opportunities!

If someone asked me how bad it is, I would indicate different people have different levels of tolerance but the plane noise is loud enough to interrupt conversations.  

I would start with a conversation and tell them they can go the easy way or the hard way.

Obviously, lowering the fee and raising the rate is an option but that feels a little bit like spinning my wheels.At some point, if I'm dropping my rates far enough to compensate for a high cleaning fee, we get into the conversation of "is it even worth it to rent it at this rate and risk property damage, 4 star review, etc".

If the Cincinnati market is your choice I would love to have a conversation with you.  

Conversations with brokers in the market are also helpful.

I've had countless conversations with heirs who spent a long time trying to figure out how to make money off of land or buildings, but without experience, and never got anywhere a year later.

How are we here having a conversation like it is even ok to let the statement "Multifamily is Pay to Play" in the first place?
