Tools were recovered and pest control was terminated.So we are naturally in a very secure area in one of the safest cities in CA.  

So, back to the original question of what if you just found natural buyers for homes?  

Quote from @Stuart Udis: The natural buyer of the entry level SF homes have limited cash and therefore the biggest obstacle they face is funds to close.

By nature a business is all about cash flow, equity is second.

I also assume a 3-4% yearly rent increase, which naturally increases the vacancy and repair amounts over time.

The key factor is the amount paid and the nature of the payment, not the payment method.

Then since your out of control your subject to human nature.

While it’s not impossible to close in mid December and still meet all requirements of the STR loophole, it will be extremely difficult due to the nature of hitting 150 hours, having it rented for 15 days or greater and having the avg stay be no greater than 7 days and not a decimal more.

If they are not changing their personal lifestyles to adjust to this, not communicating, doing new deals leaving old ones to wither then you know what your dealing with the goal ( human nature i guess) is to keep lifestyle intact at all costs.

And very rarely does a market hold it's position measured over decades as there is a natural cycle of growth, maturity, decline, redevelopment, growth, maturity, decline, redev...... - OPPORTUNITY COST: The 1 constant in life is CHANGE.
