I am a fellow investor here in Atlanta I have STR /MTR/LTR feel free to hit me up will be happy to point you in the right direction. 

So I am looking for information on what to use as the base/patio material. 

Our next door neighbor is deceased, according to property records and we always thought the property is vacant but someone showed up and started throwing bricks at the new sliding door we installed, my workers heard the loud noise and went to check and they claim to see a weapon on his hand and fled the property. 

That's going to be up to your current servicer but my gut says, they won't drop the PMI until the reno is done. 

Can I put up cameras on my multi unit property? 

Just for kicks, i looked up a few sf properties sold last year and see that land ranged from 40% to 60% so without knowing your property specifics, dunno why your land would be assessed 70%all i can suggest is look at comparable sales and see what the ratio is and then appeal using that dataalso i remember many years ago, a home was assessed higher than the transaction amount and after failing to reach agreement with assessor office, the homeowner reached out to the different elected city reps.

Most likely no note buyer would buy this loan based on those facts.3.

I am starting from the ground up and i'm open to any and all advice.

This topic comes up every single election cycle.

Feel free to reach out or send me an email I can walk you through a few locations based on your preference.There are also some other great counties that a lot of people are not really talking about yet I can share those as well.
