@James Tsuffis , I apologize for the late respond, just came back to the US after visiting family abroad.It is extremely challenging (trying to keep it on the positive side...) to find a decent 4-plex in B-C area around Los Angeles or better areas of San Fernando Valley, with my low-newbie budget, and still use it as the main residence.

I apologize if question lackks clarity but ultimately I'm just asking for tips on where to go from here.

Apologies if this is the wrong forum, seems like a general question to me?

apologies if that is the case. 

My apologies, yes.

My friend apologized, insisted we would talk with the tenant about having the dog leashed at all times when outside so that he could't wander into the neighbors yard to relieve itself.My friend had the conversation with the tenant and that was that for a couple months as it appeared the problem was solved.

Whenever someone gets in your way, just be sure to apologize twice and you basically know what there is to know. :)  I definitely agree that starting out is hard. there are a lot of obstacles that seem to be in the way, and while most of them are in our heads and can be somewhat mitigated with education, others obstacles demand faith from others, which is harder to overcome without experience.   

One thing to keep in mind with the 3.5% down FHA loan though (someone correct my please if I'm wrong, and I apologize if I am) is that you will have to pay PMI for the life of the loan.

@Hattie Dizmond I apologize.

Great idea, but I apologize for not mentioning that it's not the back door.In answer to your question about the sheet rock, the exterior walls are actually block with stucco on them.
