We can say with confidence that those buyers will not consider the financials rosy, but conservative.Please update how you are doing vs projected.

I've considered areas close to the Falls, but sellers seem to price it a lot higher assuming the buyer can make it up renting it short term. 

You have to disclose all of this when you sell, so you will end up paying your plumber or discounting to your buyer.

My basic underwriting making some standard assumptions on HOA expenses, 20% down, 7% interest rate, 30 year mortgage, utilities, supplies, and maintenance costs shows a loss of about $22k per year if you are self managing.

Also, people who are motivated to sell quickly may find there are buyers who want to buy quickly, and at a discount.  

So anyway one can pay the  20k and get some basic theoretical knowledge but one should be realistic this is a big cash up front business.. your not going to find consultants doing this work on the come.  100% agree.

I'm seeing new neighbors of basically identical houses with maybe 50 or more investors in the community. 

By highlighting properties in high-demand areas like San Ysidro that are ripe for SB-9 developments, you'll attract savvy buyers and investors who are eager for strong returns.

@Craig Holland Land is often sold with owner financing, in part because buyers have a hard time financing it, and in part because buyers often only need a short time before they can build on the land and refinance out of the seller loan. 

You'll want to put together a personal financial statement (basically lists of all your assets and liabilities) and have your tax returns ready.
