Some commentsBrrrr is definitely possible in San Diego but it is very challenging to extract the full investment.  

I aim to take an undervalued property and raise to market value (maybe even just over it) similar to the BRRRR strategy, only I would sell it rather than refinance to extract my money.

We were just action oriented and even if we lost money, we treated these units as a mini pension, so when we pay off in next 20 years, it’ll just pay us a steady flow of income vs. us wasting money on consumer stuff since we are natural spenders. 

Unless you're independently wealthy or have a natural way of getting your hands on some cash to invest, I've found this is a team sport and takes a great deal of patience, perseverance, and persistence.What are some of the best ways you've found to grow your portfolio when the money was tight or you didn't have any cash to start with?  

Naturally, pipes burst on a 2-degree day, which was also compounded by the wrong size HVACProblem 4- This really isn't a problem but it reflects some of the BS that gives some contractors a bad name.

If you had refinanced it after it had 33%, you could have extracted all of you initial investment at 75% LTV and been on infinite return.  

Naturally I expected a sphere split to me of 70/30.

@Ruslan NazarenkoHCOL area will also have greater natural appreciation and low cap rates that increase the return on increasing NOI on a commercial property.LCOL area is much more efficient for your money initially.What's right for you depends on 1,000 different factors all unique to you but it will come down to what do you want to do, how do you want to invest, what is your timeline for investing, where do you want to get to, and how much risk is a tolerable amount?

I would like leases to be issued as smart contracts on the blockchain to take advantage of their immutable and instantaneous nature.

If you are naturally good with numbers and analysis, then get good at analyzing deals and looking at financial statements.
