Quote from @Chris Lo: Which platforms/websites do landlords use to find the rent rate, how long the rental properties have been on the market, and all the details about other rental properties?

To clarify some details that I should have mentioned earlier:I am in no rush to leave my W-2 position, as it provides great security, a steady income, benefits, and a stable foundation.

Very important detail. 

I don’t know  the specific details of your situation, but there are other considerations and options as well.

Thank you @Samuel Coronado for all the great detailed info! 

First, I’d check the sale documents and listing details to see if the property was explicitly marketed as a triplex.

If you don't mind, could you go into a little more detail?

If so, would you mind sharing property details (Bed/Baths/# of guests etc.)I am eyeing into Cashiers as well. 

Forgot one detail the new California based lender committed to funding as long as the property isn't in an evacuation warning area.

Thank you so much for taking the time to give such a detailed answer.
