Given the market conditions and your hard money loan, it might be wise to first calculate your monthly holding costs, including loan payments, taxes, and maintenance.

You can use it as a downpayment on a property over $450k and use leverage tax free.

During escrow converted it to a Roth and paid the taxes.

You'd have to stick to tasks like messaging guests, scheduling cleaners, etc.

When you live in that duplex for 2 years and then sell you'll be able to take 50% of the profit tax free (the allocation for the side you lived in). 

I agree with the others here that say you need to have some skin in the game, if you are going to live there yourself, get an FHA loan rather than owner financing, you can get a 3.5% down loan, personally I do not love these as they require  PMI which is an additional expense, and you also need  bring additional funds for closing at least for taxes, title, attorney and transfer fees . borrowing from anyone else for the down payment, to include a personal loan from the bank is not a good idea, those again will be higher int. rate.

This would end up getting you some tax benefits and extra cash flow that could help you leverage that into another property...maybe a 1031 exchange.

We have sold (tax free), kept as long term and/or short term rentals as well.

I pay $875 (including principal, interest, taxes, and insurance) and rent it out for $1,625.

So, when Trump changes to no tax on tips I feel inclined to change my rental income structure.50% reduction in rent.Previous 50% made up from a mandatory nontaxable tip.
