In assessing the use of equity you must also understand that due to the opportunity value of cash buying cash flow with equity to create artificial cash flow is extremely expensive.

I can understand the concern because of the odor, but your question did not include smoking marijuana or taking marijuana pills for medicinal purposes. 

Certainly at the supermarket.But, it's not that simple.Interest rates are artificially held low.

It is therefor beneficial to have a 30 year as opposed to a 15 year mortgage.Equity in a rental is artificially buying cash flow at a very high rate based on the opportunity value of cash.

And if there’s $75K worth of rehab the owners annual expenses are likely artificially low, which is likely what created the $75K need in the first place.

You are paying a very high premium to purchase perceived cash flow and have actually turned the property into a liability as opposed to a asset.Your property with rent at $1000/month is far too low for a property valued at $150K and is already negative cash flow when accounting for the artificial cash flow that you are buying with your own cash/equity.

What i would like to know is how increasing vacancies in a class A apts effects b and c properties.Also have to remember we are in year 10 of artificially low interest rates, and this financial engineering is INTENDED to rev the stock market and inflate asset values.And the next logical question is what happens as interest rates go up?

The law has kept those property taxes artificially low, regardless of how much their true real estate value increased over the past 10 years. 

I am currently working with a Silicon Valley startup to customize Artificial intelligence based systems to help property managers and tenants with security and other maintenance issues.

Lets see...take two years out of your life to satisfy some BS leftist law in California just so I can buy an artificially overpriced property?
