In my timber days I had a custom data base of every timber property from Oregon CA border to just south of Tacoma WA.. between the Coast range and the Cascade range.  10k plus property owners.80% of the time phone numbers were on the tax records in Or and WA.. and in the 90s we used the reverse directory.. it was a big reverse phone book you could buy..

Is there some way to do some sort of cascading payoff, where I take out equity, pay off one loan, move it to LLC then refi and take out equity to do the same for the others?

Cascade Locks is up in the Columbia river gorge..

I also rent very well in the winter due to being close to Cascade, a ski hill. 

Take for instance Hidden Valley Lake in southern Lake co.. its an Old Boise Cascade development one of 27 they built in CA in the 60s... you could buy a nice home there 20 years ago for 125k and under..

I could charge a very low entry fee, with cascading levels as people progress through the different stages. 

You can probably rule out cascading defaults as a potential risk:Supply vs DemandWe are way behind on homebuilding.

Seattle is a perfect example.. just hop over the cascades and live somewhere in the Wenatchee area or the WA wine country.

Churchill of Thompson & Churchill told The New York Times in 1929 that he was introducing the cascade of color to fight what he called “the monotony of flat surfaces†common in emerging modernist designs.In September 1929, news got out that the Metropolitan Life Insurance Company was considering a 100-story tower on the block just north of its distinctive campanile of 1909, at 24th and Madison.
