I believe now is a peak of the prices there.

But, assuming this is a fairly accurate number, the little I know about San Diego (and quick look on Zillow for multifamily properties) seems like $1.5mm is the minimum asking price for two units.  

I saw how that proposal is basically her giving me a 0% loan, but at the same time I believe that structure will avoid her taking a large loss (approximately 30k if she accepts a 300k offer).I do not know why she doesnt get a PM, I only share the facts of when she purchased it, the purchase price, and the reasoning she shared with my realtor as to why she is selling after such a short time period.

However, there are other loans designed for fixer uppers referred to us hard money loans, bridge loans, or fix and flip loans but whatever you want to call them they're essentially short term, interest only loans with no prepayment penalties designed to finance a higher % of your purchase price and typically all of your renovations not to exceed a certain % of the ARV (typically 75% max). 

Even when the market is down, gradually adjust rents so tenants don’t experience a huge price shock later.

Keep track of the prices on Vrbo and Airbnb.

Some, but not a lot of choices are rare do any of the prices make sense to me.   

I now offer "limited service" as a PM for 10% which includes marketing on 20+ channels, 24/7 guest communication, daily pricing, automations and software connections, but it is 10% of revenue. 

You might find the answers to your questions there but I know that the search function is less then optimal so feel free to send me a DM if you don't easily find what you're looking for.I've never bothered commenting much about Canada because, until recently, it made no sense for US investors to invest in Canada: much less favorable mortgage conditions if they could even get one, much more expensive prices on average and much less profitable on average.
