True passive income is SOOOO much more important that active income.

Its true.

As you can imagine, this is completely devastating, and something - if true - I wish I had known about earlier. 

What everyone is saying above about buying in a flood zone is true, if the property is on a slab.

But, it's also true that every property will have a number that makes it a deal that works!

I plugged all the numbers into the Rental Property analyzer calculator, as modest as possible trying to determine what my unit would cost me after subtracting all other expansive, for example, 5% on Maintenance, vacancy, capital ex, and 11% management fees. that number is roughly $900 a month or $10,800 yearly that I would be responsible for. both scenarios look like this  A) Primary Resident: 69k (10% down + closing) +10,800 = 80k the first year VsB) Investment Property: 159k (25% down +closing) - $4704 ( $392 monthly cash flow) = $154,296 first year I feel that option A is the better option in year 1, but I can not figure out a true representation moving forward after the house hack is done and I replace myself with a tenet?

To have it in my name would be a dream come true for my younger self! 

They are true (as generalizations) but the exact numbers will vary by market. 

@James Kovarovic Very true!

The sellers realtor said they had a cash offer after our contract was signed, we don't know if this is true but even so is this the new normal for a multihome?
