You as a Realtor don't have an equivalent of "upload a W2 and some paystubs," so it would just be your sense for their motivation level as someone who has been around a while.

Through automation we are able to make our operations more cost effective and with the rise of folksonomy and the sharing economy, smaller scale operations are now able to compete on a marketing level with legacy name marks.

Therefore, the main thing to keep in mind is that even if a market crash happens on the same level as the 2008 financial crisis, in the long-term (5-10 years), you will still be in profit.

Generally I would say that we're very much at the highest point pending correction...prices have begun to level off, the correction that will take place will be nothing near a recession.

You can swap those points for rate at a ratio of about ~0.5 points for 0.125% to rate (depending on the whims of Wall Street on a given day, it might be 0.546 today and 0.416 tomorrow), which lenders typically do ahead of time when quoting a rate, since we know without asking that no one wants the rate that comes with $15,000 in lender/Fannie fees.Individual lenders can impose additional "loan level pricing adjustments," but typically only do so over FICO score issues, or when it's not a Fannie loan.

Not quite on your level yet, but still a decent clip away 538 miles!

I would factor in your personal finances into this.I'm not saying real estate investing isn't lucrative, but on a macro level in the next few years I expect to see a down turn.   

If I wanted to qualify for a bigger mortgage, I could work more or plan to take capital gains to achieve that income level. 

Unfortunately, the areas you're targeting are a bit beyond my expertise/comfort level.
