We both have full time jobs but want to establish a revenue stream so we can retire early.

I got a permit for it (an Accessory Dwelling Unit, required in Bellevue, WA) and I live in that unit (when I am in town). 

I own a duplex in Oklahoma and I have a rental dwelling policy to cover that property. 

I'm not sure you are correct that the Certificate of Occupancy is classified as "Miscellaneous Two Family (B9)".See Snapshot here:Note on the DOB website, one of my properties is classified as "B3-2 Family Dwelling."

I want to help people get themselves out of debt, or at least into something manageable for their income stream. 

My property acquisition is going to be more of a slow burn, and figured while we are managing our own properties it would be beneficial to have PM as a revenue stream as well. 

Based on the properties I've come across, multi-family (duplex, quadplex) dwellings provide decent rental returns.

I was a director for a Fortune 30 company and left to pursue my business growing my active and passive income streams while helping others in the business too.  

Thank you Account Closed  I don't plan to get a loan or have a mortgage payment and pay the house off with a large down payment and the rest from my jobs streams of income.

It then will also protect all receptacles down stream.
