I would target areas like North Everett, Lake Stevens and Marysville.

Pay down all debt two months before applying and get a co-signor that has income.And/or do commercial financing so you can use the target property's income.

Therefore I suggest bookmarking a fe links to access resources like checking out these calculators , the file place, REI resources, and looking into getting some or all of the really awesome and necessary books offered here on Bigger Pockets.

Its so many resources for buying and holding I'm looking for strategies to buy and flip consistently and hold onto my house at the same time.

After you talk to a few reach out to other investors in your target market and ask them their opinions on your favorites.

I target my all-in costs to be as close to the 70% as possible.  

Or any thoughts on a good resource for how to lay out the terms for owner financing for something like this? 

@Christopher Phillips  An elderly list is a good target.

I have a few target sub-markets that I'd like to pursue. 

The lease terms must be over 30 years but less than 99.A master lease has some of these aspects, but does not have the advantages of NNN leases where you can get a mortgage on it as it's treated as real estate.I know an investor who does these deals in NY who targets owners owning properties for a long time, don't want to sell due to capital gains, too old to manage the properties.
