Quote from @Jordan Kaylor: What is a “seasoning requirement”?  

In California the DRE does not require you to join any association.

One of my buy box requirements is the house needs to cashflow at least $500 per month or I am not buying it. 

If you are nearby, if you have ever been a pizza delivery person, maybe deliver a pizza to the wrong house that may or may not be the one being foreclosed on so atleast you can see inside a small portion. we used to just go knock on the door some folks would actually let you look around.

It will be a can of worms for sure and they may go as far as requiring a full tear out and fresh submittal.

There is no seasoning requirement involved since the property isn't a short sale and it isn't someone buying REO from a bank with a seasoning requirement.

Send it by US Mail with proof of delivery required and/or place it in an envelope with their name on it and post it on their door. 

Most building codes and HUD standards require bedrooms to have windows for egress and ventilation.

I did do a precursory investigation into what requirements are and it looks like there might be some zoning restrictions, as well as permits required.

So I’m trying to come up with a game plan  Conventional loans do require 25% down on an investment property.
