Your problem will be them incurring capital gains taxes simply so you can get a commission.

@Daniel Tanasa $1905 per month (mortgage +interest) , taxes (around 3600 per year) and insurance (1500 per year) => so 2330$ is my PITI

As someone mentioned, the only thing passive about real estate investing is the tax treatment. 

Things in your tax filing need to be really off to do this.Being a REP/active participant and using cost seg to offset a spouses (or your own if that's all you do) W-2 wages is fairly common practice.

I agree with the others here that say you need to have some skin in the game, if you are going to live there yourself, get an FHA loan rather than owner financing, you can get a 3.5% down loan, personally I do not love these as they require  PMI which is an additional expense, and you also need  bring additional funds for closing at least for taxes, title, attorney and transfer fees . borrowing from anyone else for the down payment, to include a personal loan from the bank is not a good idea, those again will be higher int. rate.

So, in your considerations, I would park right there for a bit and determine how this would look for you.Since you have about 2.5 years to think about it before you would need to spring into action to take advantage of the rollover for tax advantages, maybe you try on a rental and see how it fits.

Maintain - includes taxes and insurance?

@Emily Gowen so as you pointed out you would not have to do a 1031 exchange on your current home to avoid the capital gains tax and coupled with what Dave Foster pointed out I think, speaking from experience you would have a high likelihood of success. 

I also suspect inflation will drive continued migration to lower cost of living / lower tax states.
