I personally wouldn't buy a condo as an investment property unless you don't have a primary residence and plan to house hack it (e.g. buy a 2 bedroom and live in the unit and rent out the other bedroom).

Buy one and see if you like managing it.  

I joked on another post that I should start a cat tree flipping coaching program (buy cat trees on Amazon then renovate them with top of the line cat toys and decor (Disney theme, bird theme etc and charge more, which is the flip)...someone might actually pay for it lolI agree with you there agents who are licensed and not competent, I attended an open house here and the agent didn't know about non-QM financing.

The house was built in the 1800s and although it is zoned as a multifamily, it has never been used as a multifamily before us.

I own and manage an incredible property called the Kailua Kona Estate (you can find more details at www.kailuakonaestate.com).

If they 100% refuse to deal and its take it/leave it, then you need to decide if you're willing to buy the house with that issue. 

Maybe set up the LLC as a property management account and use that to operate your rental business.

Additionally, consider hosting open houses to increase visibility.

I know a good property management company in the area that help several of my friends and neighbors with their rental properties.

I have a gutted carriage house on the back of my property, so my thought is to get my feet wet with house hacking by creating space for a longterm tenant.
