I do a lot of work on the side and feel my skills could be of use in the right situation.

If you don't want to stick with the day job you may want to consider researching a creative option that doesn't require you to qualify for a mortgage, like Subject-To.

Only a SFH qualifies for 100% financing. 2. 100% financing can't be used for investment properties. 3.

Though it would be essentially paying myself, I'm hoping that might be hands-off enough to qualify. 

I'm pretty skilled at building maintenance and improvements, and between my own experience and the property manager I've got the business of running the rental properties dialed in fairly well.    

Consult a mortgage broker to find out what you can qualify then go from there.

There’s a type of loan called an FHA loan where you could qualify for a low down payment.

If so, are there any requirements that need to be in place to qualify for the other address?  

But if you claim this on your tax returns, and your tax returns are used to qualify for future properties, then those depreciation items are added back to your qualifying income. 

I do not have any real estate specific skills, but I work in finance so I'm reasonably comfortable with numbers.
