superjames, despite being “famous” now, your original post was extremely lacking in any detail and your follow-up post shed no further light on your situation.
To have “just started renting out a small unit”, did you
a) buy a new unit off the plan and rent it out straight away as an investment property?
b) buy an existing unit second-hand and rent it out straight away as an investment property?
c) you have owned and lived in this unit but just moved out and started renting it out as an investment property?
If a) then it is a given that there will always be many (hopefully minor) defects that the first occupant will pick up, and you simply get the developer to repair as per your defects-period in your purchase-contract.
If b) then there have simply been a few minor issues passed over to you in your purchase, and your purchase contract would allow for minor issues (unless you found cement rot and the roof was about to collapse you have no real claim – you've had opportunity for yourself and a professional to inspect it before buying it).
If c) then are you claiming there was absolutely zero issue with every single power point and light? Even if so, its not a brand new unit, things fail. Deal with it.
Regardless of a, b, or c, they are minor very cheap problems. An electrician, or even just a handyman should be able to fix all those issues for about $100. Getting replacement fan thingy grill thingies is probably the hardest one, finding “spare parts” for the right model. Maybe a handyman can just dodgy one up for you. Depending on a, b or c – are the grills missing a) from the developer (if a new building, he's probably got left over grills sitting in the basement wondering which unit he missed putting them in – very common), b) were they already missing from the previous owner? They might have taken them out to clean them when selling the unit and then accidentally packed them in with their removalist boxes, they might just give them back to you, or c) if you lived there, do you know of they were in there or you didn't really do much cooking?
Either way, if you have a tenant that pays rent well, looks after your unit (and a tenant who actively wants everything working is usually a good sign that they take care of the unit themselves!), then pay $100 or so and keep them happy, and they will keep YOU happy 🙂
PS. I bought a new unit off the plan, unit looks beautiful, but the developer imported everything (and I mean everything) on the dirt-cheap from China, and then declared bankruptcy after the sale so no claims could be made against him. We had to replace every single power point and light switch as they were flimsy fragile plastic that just snapped after a bit of use, had to replace the intercom and security system, the gas stove, the garage roll-a-door, the roof-top planter boxes had to be emptied and properly water-proofed, the lift needs to be almost totally replaced because of water damage, some wiring had to be re-done correctly, etc, etc, etc. I would be so happy to only have to replace one power point, fix one light, and put in a couple of grills…
Cheers,
Jono.
