What is your ARV in excess of your cost basis? 

I have this theory that basically the stock market can grow faster than the fundamentals more so than housing, reason being when people put money into their 401k or whatever they are just throwing money in, not looking at p/e or whatever, the stock market is in part just an index of Americans excess savings plus it’s a unstated policy of the government that stocks go up, where as housing people are obviously very very aware of how much thier monthly payments is/ how much rent is, plus it seems that is actually a push to lower housing prices at least relative to inflation.

But if they use it to excess, then the electric bill will be much higher than anticipated and if that month of high electric comes during a time that the tenant is facing hard times, they are more inclined to pay for their heating than their rent.

Is it your actual savings or was this saved to invest, because there's no such thing as "excess" cash.

When you have unscheduled entry as an option, I think it encourages them to do weird stuff like hide stuff in weird spots, etc because they are always on guard.Hoarders clauses would have to be linked to fire codes I think for excess people and materials near fire sources, etc.

In some far left localities you are seeing rules that are very much in excess (less restrictive - Wild West) of the state rules.  

Income reserves in excess of 6 months living expenses, no consumer debts, leveraged mortgages with no payment coming out of pocket.

California charges a minimum tax of $800 a year per LLC, and more if you have gross receipts in excess of $250k.
