Hey Christopher,
Your heads in the right place, mitigate risk! It's the reason why as a lender we rarely exceed 65% LTARV even throughout the housing boom this past year. While this protects the lender, it also protects our borrowers by only taking on strong projects with a lot of equity. Also, it's worth noting that during this time we still had borrowers find off market deals that were far below market value. Of course finding a hungry real estate agent is always a huge help as well. Few more pieces of advise...
Rule #1 for any investor in any market is "the money is made on the purchase". This will hold even more weight during down markets. Never plan on being able to push the market prices or saving money on rehab, see next rule.
Rule #2 rehab budgets will always end up being more than estimated. Whether that be due to cost of inflation, contractors underestimating the project, or surprises you find "behind the wall". Be prepared for this.
Rule #3 start small, don't over extend yourself by taking on too many projects at once. One bad deal early on in your investing career can be devastating. One bad deal later in your career is just a bump in the road.
Rule #4 Be patient. Say no a lot more than you say yes as deals will continue to present themselves especially as the market nears the bottom and starts to come back up.
Hope this helps. Happy Investing!
