We placed our biggest bet on a single property, class B shares.

I have seen this, and unfortunately it was done poorly.

You could certainly reach this demographic, but it could also cost you substantially more than the return.For the money, your best bet is probably a dedicated website for your property with the key words that you want to convey.

The main downside is being dependent on the HOA—issues like poor management, rising fees, or unexpected assessments can hurt your investment.

You do that, it's going to be best place to start because I am betting from there you will seek how to simplify things. 

Another "perfect storm of uncontrollable events".With both failed deals they are pointing blame on poor performance from the companies they hired to manage the property and to do the renovations, which raises a few questions:1) how can/should LPs perform due diligence on these to be hired companies?

hi all i am a new landlord and got my first rental property. tenants moved in in September and October. the first month was fine but when December hit it got extremely cold and the heating is electric. due to poor insulation in the home that we did not know about the heat has to be turned very high up to keep the home warm, however since everything is electric it is causing the electric bill to be $800. the utilities are the tenants responsibility. however because of this one of the tenants has been extremely non compliant with paying rent.

The Los Angeles fires are likely to make a poor situation worse.  

Nothing is a sure bet.

I would bet the solution lies in your answers to those last three questions.
