He is thinking about adding a 2bed/2bath to the backyard or next to the house.My mom is 60 and my dad is 59.

When you buy a stock worth $100k, you pay 100k. 

@Alexander HunterThe market in Australia is not worth the effort on a value/risk reward basis.

Because this is your first rental property, I would recommend finding an amazing PM company and paying them what they are worth.

I would say it's not worth rocking the boat for less than $200 additional per month, when you look at what you're overall ROI. if it's really that big of a deal to you, maybe consider canceling the pest services that you know are being utilized and would facilitate not having a roach problem, so that you can save that extra money every month and have that money back instead of raising the rent price to the tenant.I have seen this in many different places, Metropolitan, rural and otherwise, and it doesn't necessarily matter with the market rent is you're not always going to get that.

That said, staying on top of losses and basis is important and worth the cost of a CPA.

That’s 850K worth of debt.

As an agent, you are really going into business as you mentioned for yourself with an added layer of support though.

Has anyone had any luck with this and is it worth it?

Just to clarify-Are you simplifying the amount to $19k for this explanation (But gave him an exact figure)....or did you put $19k on your line item to him but the receipts totaled $18,308 when he added them?
