This will allow you to properly support the overhead weight plus support your ceiling joist expansion lengths.

I suspect buy & holds will be rewarding, especially after the 59 expansion is completed.  

High end got clobbered as you will recall 50% in some cases.. my brother in law bought a home in LA hills that was worth 2.5 in the mid to late 80's and he got it for 1.2 in 1993.. it bounced back to 2.5 by end of 90's then shot up to 4 mil... then 08 it probably came back a little but I am sure its right back up to 4 to 5 mil..the dot com created spike in value late 90's then the dot com bust dropped prices then they came roaring back and by 2006 to 2007 made new high... then the 08 09 crash.. and it retreated again only to come storming back as you said with the google facebook and all other manner of high tech expansion and profitability.. to make new highs..

This is a deal where I might be able to trade out of a few SFRs where my basis is $120k and I'd be buying for just about land value with room for expansion.

From there, I plan on continued expansion that supports my retirement and my family overall.The BP podcast heavily influenced me. 

Real estate in most markets right now is in the expansion phase (crash, recovery, expansion, hypersupply, crash again).

Vinyl siding is hard to screw up as far as ruining the siding but you can make it look bad by hammering too tight, not leaving expansion room in channels, etc. 

Also, I need to put a "temporary" roof because the house will undergo a gut renovation and expansion including adding a floor.  

However if the actual prices in Charleston are driven more by growth and expansion, rather than pure speculation, and unless you anticipate growth slowing and jobs being lost, then probably not.

I could list all the "less than 20% down options" here [subject to, a wrap, lease-to-own, syndication, buying at the right price with OPM (other people's money), where you then cash out after your rehab at  break even out of pocket if you ran your numbers right], but I'll defer to the venerable Brandon Turner for the expansive "Low or No Money Down Guide" (http://get.biggerpockets.com/nomoneydown/).
