There is obviously a formal lease, and we also supplement with a room mate agreement which outlines the more specific things like overnight guests and expectations in dispute resolutions/ cleaning/ care for the home and appliances, etc.I haven't received one formal "LL request" email yet, other than a formal 30 day notice in the event of a move out, which is usually after they've come talked to me in person about it to begin with. if there's an issue, it tends to be pretty limited to "hey, we have this shower rod falling off"... which im usually here to deal with (and tbh most of the time they like to fix it up with me), and it doesnt need to turn into a big thing. as for keys, i have the house on a yale smart lock, so 'handing over keys' is just official move out, walkthrough of the room for damages, and then I can delete their access code and access to the smart home systems without having to re-key the house. 

We aim for 100% occupancy, which is possible in theory if you exclude properties that go through a scheduled rehab.

I aim to be at 25 doors by the end of this year. 

That's my aim here - solve problems for others and make money doing so. 

I wouldn't aim for the highest; I would go for an average of rent prices in the area.

We BRRRR 8-10 per year and the flips supplement the money left in the BRRRRs. 

I think we both have the same aim in this forum, which is to share our experience and information and help people buy real estate with the lowest risk possible, provide factual information and help define options.

We aim to start with flipping houses to build capital for more significant future investments.The high cost of properties in Sydney is challenging ($2M), so we are considering exploring a more distant but cheaper market.Is it a reasonable strategy for first-time investors?

There are other forms of winterizing like insulating plumbing, sealing door/windows with rubber gaskets, installing storm windows/doors, setting up heat lamps or other supplemental forms of heat in basements, etc.
