Regular old savings or do guys have a more interesting idea?

I am paid at a different (higher) split for my own investments vs regular "retail" real Estate transactions with my brokerage.

I get regular inquiries for people who need a place for 3-6 months while they build.

Hard work pays off since it enabled many individuals to attain similar goals!

should I open it as a regular checking account or business? 

., turn-key properties (likely in other markets since the Seattle area really isn't a buyer's market at the moment) are most likely the best fit for me.I'm a partner of another business, and am looking to regular income from rental properties that do not require a lot of my time...I already have a full time job to manage!

Both are in the same general area I invest in regularly.

A good wholesaler can bring a lot to the table, but most good wholesalers have a small handful of regular buyers that they consistently use over and over again. 

For me, because I have the rental income and a "regular" job, I really need to continue to grow until I retire in order to offset that income.

So I will treat this operation as a regular Purchase of house with mortgage included, freeing myself from the building process.
