The many new startup attempts at mimicking these real estate search engines haven’t appeared to gain much traction.

Because it takes a while to get traction I’m not sure I would commit to CA but that depends if you plan on going back at all.

Then after you are ready move to your strategy, which may change as you gain traction.

A hot tub is a great idea, just be careful about locking down the controls and get a remote device connected so if you're away you can adjust it. 

They can be standalone, but you'd want to have something that communicates through the internet to your mobile device. 

I’m interested in the same solution to open the door for prospective tenants without being there and without depending on an agent.Do you know any company that does these bluetooth devices? 

We do not ALWAYS run move in specials - this depends a lot on the weather, our competition, as well as the traction on that particular property.

I do agree with everything you said and it definitely takes tenacity and patience to overcome the initial inertia and gain some traction as an investor. 

For example in my area Sheetrock is $25 per sheet hung and taped, roofing is $300 a square installed, electricians figure one hour per device, framing is $1 per square ft.

In that case a locksmith would help. if it is any other device made to secure the door, then use a drill or elecrtric saw to cut it.
