It is about 2-3 times more efficient and cost would be similar ($200-300 for 400-500 square feet heat/cool) http://www.ebay.com/itm/Amana-APN12HJ-Heat-Cool-Po...Biggest hurdle is drilling a hole in the wall and getting tubing to drain condensate.You could also look into a ductless minisplit.  

@Bryan HancockTraditionally, in my businesses, I've tried to maintain 20% of the long-term debt, or 4-6 months payroll, as liquid capital - cash & further credit facilities (LoC).  

:)what turn key does for most is it gets the investor who has say under 50k liquid into the game.. good bad or indifferent this is where many start.. so choosing wisely is critical on all aspects.

It's a very cool tool that does what you ask for and more.It receives requests, coordinates repairs (very cool), reminds parties of work to be performed, follows-up with tenant, pays vendor, tracks costs, and more.  

Not to offend Anybody but I know also Real estate is a Up and down business my family is been in Real estate for 4 Generations so, a lot of mentors are has beens, which made a lot of money or maybe just gained a lot of experience, and some exaggerate what they really did, like many people do and that is fine, some do it just for the pleasure of helping and who doesn't want a little extra cash flow my business is based on the Mentoring kind of, since I am Consultant for some big private equity firms, and private individuals but I share my knowledge for free with some cool guys some other guys who think they are super cool themselves if you know what I mean I charge them a lot cause I don't want to be dealing with them if I am not getting paid, I am sure there is many different kind of people that do it for many many reasons. but just remember not everybody that wrote a book on how to flip houses is millionaire, and not everyone who became millionaire wrote a book on flipping house is a tricky industry, I am glad you have had a good experience when I was studying to get my RE license way back when I was 18, I had a professor who brag about living beachfront, brag about selling 10-15 homes per month, and I was very confuse why does he teach a night class at community college so I look into it as any young kid would do and it was all a big lie....Ps: we love Downey, was one of the first areas my family build on south Downey 25 years ago   so watch out @Tommy Martinez

Its a cool idea but not yet completely feasible for this market. 

It could happen, but the market could just as easily cool in the next 12 months.

My LL is cool like that...A limited thermostat will do nothing.

Assuming that you unit has central A/C that should more than keep your tenants cool.

It's cool to see that most people either put down on a rental conventional or move and rent their former home.
