I'm currently building my "power team" right now, and a good contractor is a MUST.  

With an understanding of your goals and financial power, you can get what you want.  

No idea how much it costs to get it ready, paint the stripes and install the solar powered credit card machine.  

Also consider that because your 401k is tax advantaged the power of compounding will be significantly greater there.

I use those fake cameras that you can put a battery in so they light up at night and I put a smile your on camera sign visible from curbside.

Hand tools and power tools get buttoned up and brought back to the shop daily, which makes it super easy for my lead carpenter to keep a running inventory.

Problems start due to CA REI's:1 - Lack of MI Market knowledge2 - Lack of Power Team in MI3 - Distance4 - Management5 - ...and more.This is why I stopped going with the traditional Turn Key model with my CA (and other OoS) Partners.  

He has a video about 1.5 hours long (i believe its called the power of zero) on buying apartments with 100% owner financing.

But you can have a cosigner go on the loan to increase your purchasing power.

For this type of application, there is not much horse power required so it should be fine.
