Probably a good reason to have a coach in-situ as having a coach who doesnt understand the local "quirks" is demonstrably useless for me. 

Several of the example properties were in places which may be investigated for environmental reasons like next to an Air Force Base or in flood plains, which, to me, demonstrates that their inflated values during the boom had to be driven by investors who were unfamiliar with the market.Inventory and average days on the market in Sacramento are two conditions that seem to be stabilizing.

In regards to the effect of interest rate rises on property values I have no inclination to do research for you to demonstrate basic economic theory.

Just keep your operating agreement on hand if needed to demonstrate to an IRS auditor that you are the underlying owner of the property.

A verified high income shows an ability to pay, a credit score demonstrates the actual history of paying.

The critical issue is that under an audit you would have to demonstrate that you had the intent to hold the property for rental, investment of business use.  

It is not unsupported if it can be repeatedly demonstrated how their methodologies are spurious and their outcomes are empirically false.

If the ground rent is not registered (registry created ~11 years ago) and the seller/title company can demonstrate that no ground rent had been pursued for 9 years prior to that, then technically yes, the lease has been extinguished.

I would spend time to learn more about RE investing especially if you plan on going out of state, appreciate your dad’s success and the knowledge he has demonstrated with his success, appreciate that if you find the right deal that satisfies your Dad’s criteria you have an incredible financing option, but most importantly look to cut the apron strings at some point and forge your own path to success (and working at your dad’s accounting firm is not cutting the apron strings).  

I ended up parlaying that into other investments, and I've been targeting areas that (i) have demonstrated strong historical appreciation, and (ii) have the right fundamentals for me to believe that will continue (e.g. more jobs being created than housing being developed, government infrastructure investment, etc...).
