Sure avoiding negative cashflows and bad long term loans (variable, balloon, hard money) are important, but an equally important factor in surviving RE crashes is where you buy. The 07-08 crash in the Bay Area played out as predicted, like a ripple effect emanating from the prime center. The very best locations- most of SF and prime towns/neighborhoods in Silicon Valley and San Mateo counties fell 10-20%. Other good areas of Silicon Valley and East Bay fell about 30%. Going outside of the Bay Area we're talking -40% and onwards.
And not surprisingly, the best areas are the first to jump back in values. In my case I invested in a gentrifying SF neighborhood (Mission district) and even I was surprised at the appraisals when I refinanced two condos last month. They actually came back higher then I expected. So now my properties are at least 10% over their 07 peak.
My experience in the Bay Area has shown me that prime areas are the last to fall, fall the least, and rebound the first. And that has a huge cumulative effect on appreciation.
Like many investors, the 07-08 crash was challenging. I got stuck with a gutted triplex and no loan options for renovations in 08. I was able to sell a unit to family for a discounted price, and used the cash from the sale to renovate the entire property. I sold them that unit for $350k, and later this year I will be finalzing condo conversion on that property and their condo unit will be worth $650k, so it turned out a sweet deal, and now my dad plans to give it to my sisters, so they have some security in their lives.
Another saving grace was that rents skyrocketed in SF from 2010-2012. Several of my rentals went up 30%, so having that wind to my back helped during that timeframe when the banks were barely lending (even to qualified people like me.)
With strong positive cash flow I basically treaded water since stabilizing that triplex in 2010, until earlier this year when I was able to refi and separate a former duplex to condos, as well as lock in 3.75% 30 year fixed rates, which is godsend. Now I am in the midst of refing the triplex, I plan to access some of my equity and pull $500k as I would like to buy 2-4 units in SF. With these low fixed rates it's a no brainer if I can even get close to break even. I normally buy properties that need some work and have upside, so I will be busy bringing it to higher and best use. Should be good times ahead!
