I've been fortunate enough to hop onboard the social media marketing strategy and seen incredible results compared to the dwindling snail mail campaigns. 

The construction standard comparing AUS to USA is totally different so you can learn but your not going to be able to get funding easily in either country, just too young

Then, if the house had a tenant, we compared what the current landlord was getting vs. what the market seemed to be demanding.

Using comparable sold properties with similar condition to your end product, within a 1/2 mile (sometimes a little further), less than 6 months old, within 20% of square footage, not crossing major boundaries ( high ways, school districts, city lines, etc).

Going back further in time and extrapolating present day values is orders of magnitude easier and more reliable than comparing townhomes to condos.  

Ok, back to the (now after being lowered two times very reasonable sounding price of $499,000.00J… Since this is supposed to be an analysis why don’t we compare this San Diego Price with the Stockton rents which are currently, according to the listing, $850*4 = $3,400.

The comparable home prices are 665,000 for that area.

Don't buy into that market unless you believe it's going to change and raise the value of your property (appreciate).When doing the house-hack thing, compare the cost of renting your side of the property with market rents for similar.

Look at $ per sq foot and $ per bd to compare with the recent sales.

How does it compare to similar properties in your area?
