You can probably start the education process at 17, then apply for your license once you turn 18.

I was thinking of starting a rent increase for my 1 bedroom tenant voucher due it being low and well under fair market value(Based on  hud and zip code) but my tenant is in the process of having a caretaker for her disability and getting approved for a two bedroom voucher.

Building a trusted team is key, so starting that process as you actively search for your market will put you in a strong position moving forward.

Not sure why the process would be any difference for a voucher holder in a duplex or single family.

Quote from @Rene Hosman: @Austin Wolff recently went through this process of identifying markets to purchase in and he goes over his thought process in this episode on the Rookie podcast about how he used the MarketFinder here on BiggerPockets to find markets that met his criteria Podcast: https://www.biggerpockets.com/blog/rookie-473MarketFinder: https://www.biggerpockets.com/marketsI specifically only focused on 2 markets (Indianapolis and Fayetteville, AR) before I found a deal using the BP "deal finder."

You also will want to stick to on market properties at first because the purchase process and evaluation process (namely title and inspections) will be more defined.

My though process in undercutting the bank by 1 % was to possibly attract qualified buyers.

I've been reasonably happy with this so far, since it's made the process fairly passive. 

I did discuss with my accountant and he is unsure as he is not familiar with IRA rollover process. 

Also happy to answer any questions about the process if anyone's considering adding them to their marketing.
