Zip codes are often too big and you'll be dealing with nuance at that level.

@Scott Stampsi don't know anything about it but i am just curious:what your experience level iswhat you're hoping to accomplish

There are places that are tenant friendly and then there is California which is at another level completely.Have you thought about buying elsewhere? 

The entry level point for STR's has risen to the $4-500k range with many now pushing $750-850-$1M+ and I would expect that to continue to increase.

There is no such absolute rule or mandate for REI - it is up to you on your comfort level with your cash flow versus total investment versus appreciation potential.If I followed that rule, I would have missed out on a LOT of great opportunities over the years.We bought a house in Jones Valley in 2017 with negative cash flow - why? 

the good news is that you're in the middle of a "masters" level education at this point.

Once you know who in your circle has $ to invest, you then need to understand their risk to reward level so you know what deals fit their bucket.
