The same info in the books can be found on the forum, it's just in a condensed and easier to read format in the book. 

My A class in  MS is in Madison and it   runs like a champ never had a house trashed ( can't tell you how many I have had trashed in C class) never had a condenser unit stolen ( can't count how many I have replaced over the years in C class Caged or not). 

It couldn't be vented outside due to city regulations so I had a Condensation Dryer.  

My situation (condensed version):I have already secured financing and have been looking for houses to fix and flip.

This is the most condensed information on the local REIA's that I have found:http://www.biggerpockets.com/forums/86/topics/98920-san-antonio-tx-reiaI am looking to join one myself.

Sure we just had 2 done recentley.It was $1800 for one (it already had a condenser and it needed to be replaced)And $2100 for the other ( new install- the house never had Central Air)I know we get pretty good pricing because we do a fair amount of volume with them, but give them a call- I'm sure you can work something out.Mike

Prove your theories about better bad areas and put an ac condenser out in back of a house.

I'll give you my perspective, take what you like from it..as it is going to be extremely condensed but you'll see the tips of the icebergs at least. 

It sounds like condensing 2 properties back down in to 1 and only financing at 50% LTV will be the game plan.

It might even be a drunk / intoxicated tenant taking his monetary frustrations out on the landlord.However, you can ask your HVAC contractor about cages and other options to protect the condensing unit (the outdoor part).
