I have built a few modular single family homes in Virginia using different manufactures. 

Kyle  My father-in-law did this by creating a portfolio that is primarily debt-free single-family rentals in the city he lives in.

I am seeking SFH or Multi-family home investment with positive rental cash flow as my strategy.

Good point - At least in FL, since I am licensed I can pay to the other agent's broker legally.We pay the same regardless if it is an RE agent or not, i.e. we pay that same rate to friends, family, current clients, vendors, etc.

I am located in Western AustraliaI have been exploring small multi-family properties and flipping houses.

Sounds like we are in the same boat with a handyman :) And to @Jonathan Klemm point, I have to weigh the mental capacity of handling issues remote versus spending time with family.

Just for fun, I attached the before and current state photos of my current flip.

The problem you're going to run into is Fannie/Freddie doesn't allow second home loans on anything but a single family residence (yes can be condo, townhouse, etc. just not 2-4 unit) so you're automatically thrown into the investment loan world.

I have attached a photo of my original property taxes along with the new projected property taxes.

Parts of Garden City Beach are prone to flooding, so if you're buying a single-family house you'd definitely want Flood insurance.
